Introduction

This is an exciting time in the mobile development technology space.  Recently, Apple released the details for the next version of their mobile computing platform, iOS 8.  With over 4,000 new APIs and core features, this platform update is the largest since Apple introduced iOS 2.0 and their heralded App Store.  Regardless of your application focus, this new release will change how you design, build, and deploy consumer, enterprise, gaming, and utility oriented mobile applications.

This blog post will focus on providing a summary (and a relative smattering) of iOS 8’s new features and the importance they will have on your current and future development projects.

What’s New For All Developers

While iOS 8 has over 4,000 new APIs, this section will just focus on the top five truly innovative and roadmap altering features that any Apple-focused mobile development team should start looking into.

1. Swift Programming Language.  Since the dawn of iOS, Objective-C has been Apple’s only available native language.  To be brutally honest, Objective-C is one tough language to get your arms around, let alone master (Objective-C is a relict from Apple’s 1996 acquisition of NeXT). But that has all changed.  Apple developers now have a new native language to build iOS and Mac OSX applications…Swift.Swift is an innovative new programming language for Cocoa (OSX) and Cocoa Touch (iOS).  Developing in Swift is an interactive and liberating experience from Objective-C.  The syntax is concise yet expressive, and apps run lightning-fast.  Writing Swift code within an Xcode 6 playground (which is something else that is new) shows instant results, while finished apps are compiled into high-performance native machine code.  Swift modules can be seamlessly incorporated into existing Objective-C applications and when compiled they will run on iOS 7 and iOS 8 mobile devices.  Given that Swift is a new language, development teams should start the process of educating themselves.  DSI is updating our Mobile Development Best Practices to include Swift-based development.
2. Extensions. This is perhaps the most requested feature by developers within the iOS ecosystem. Now with iOS 8, developers will be able to create extensions that allow applications to securely communicate, share data, and share processes directly with one another. Using this new API set effectively extends an app’s sandbox security wall to include a short-lived tunnel to another application. Once the tunnel is created, the third-party application can share data, processes, and even inject user experience components (via remote views) within the host application. During this interaction, the host app’s data and settings are never exposed to the third-party application. Also, the device’s user is in complete control to either allow or deny the connection as they see fit. The extension tunnel executes out-of-process with the host app and is always sandboxed, meaning any unexpected issues are contained and not exposed to the rest of the mobile device. This feature will fundamentally change the Apple iOS app landscape from a pallet of walled app-based silos to a collaborative canvas, where vendors can provide discrete services and features to any number usage scenarios.
3. Universal Storyboard. Since the inception of storyboards, Apple has advocated modeling and managing the user experience using this powerful and intuitive design tool. Given that different screen sizes and device orientations demand a different user experience, developers and designers often created multiple storyboards to manage the user various experience options. This meant that additional time and resources were needed to design, implement, and support these options. Development teams often had to weigh the urgency to support multiple orientations or platforms with other central application features.With Xcode 6, designers and developers now have access to a universal storyboard, on which all UX orientations and platforms can be modeled using a single set of Interface Builder views and components. Using new “Sizing Classes” and adaptive UI constraints, a single storyboard can be used to manage, design, and consolidate the UX for any number of screen sizes and orientations. Additionally, the Xcode 6 storyboard preview assistant allows the UI to be viewed as if it was being rendered on a specific device and orientation. This new toolset will allow development teams to fully embrace and support the complete range of current UX options, as well as any new UX choices (such as the rumored forthcoming iOS side-by-side multi-tasking model) or hardware changes (such as the rumored larger screen iPhone 6 or the rumored larger iPad Pro tablet). Regardless of what future features or devices become available, Xcode 6 universal storyboards will reduce UX resource and delivery times on your current projects.
4. Notification Center Widgets / Interactive Notifications. Another feature often requested was the ability to provide custom functionality and features to the iOS notification center, as well as provide interactive prompts/actions to the iOS alerts. With iOS 8 both capabilities will be available.The new iOS 8 capability to add widgets will allow apps to provide simple and helpful utilities to the notification center panel. Users will be allowed to control which widgets are displayed, as well as access a set of vendor provided settings to control their interaction with the widget. The likely usage scenario for the widgets will be to provide timely and convenient access to your app’s most central and user critical data and processes. However, widgets could also be used to provide supplemental information or provide the ability to quick launch into the application.The new interactive notifications API will allow the user to be presented with and process custom actions within the notification area and on the lock screen. This will allow the user to provide instant and secure interaction with an app’s workflow without having to switch the user’s context to the target app. Scenarios where users can reply to a message, accept an application prompt, act on an event, or even provide customized user input will now be possible.
5. CloudKit. It seems that cloud presence and features are everywhere within IT. For mobile applications, the cloud is more than a buzzword. It is a central component for providing off-device features and data. With iOS 8, Apple is releasing CloudKit, a SDK and service combination will allow any iOS application to seamlessly maintain a cloud presence. With CloudKit, Apple will provide server-based services and interfaces, as well as, provide the app-side interface logic components. CloudKit apps can quickly have a free, fully managed and hosted online presence that supports:
   • Cloud-based SQL databases (up 10 terabyte in size)
   • Asset libraries (up to 1 petabyte in size)
   • Full user subscription service with alerts
   • Comprehensive developer portal for management and analytics

   Apple is aware that developers have access to other cloud platforms, and they fully support communication and interaction with these platforms within iOS. However, CloudKit will provide developers with another cloud-based solution to leverage with perhaps the lowest cost (free – unless your needs are unusually large) and the easiest integration footprint (build into iOS and OSX).

6. Xcode 6. I know this section was to highlight five new iOS platform features, but there is another that should be emphasized – so consider this a bonus! Apple’s Xcode development tools suite has been updated to coincide with the introduction of iOS 8 and OSX Yosemite. Hundreds of new features and redesigned components can be found in Xcode 6. A few of these new features have been mentioned in this blog post (e.g. Swift language support, playgrounds, universal storyboards) and it would be impossible to highlight, or to do justice, to all of the other changes. However, a few of the other new features that any mobile development team should look to leverage include:
   • Universal document find and replace (even in Interface Builder)
   • New localization support leveraging XLIFF
   • Real-time rendering if custom controls in Interface Builder
   • New debugging options (view debugging, queue debugging, new debug gauges)
   • New testing options (asynchronous testing, performance testing, profile guided optimization, updated Xcode Bots)
   • Structured beta testing through the App Store using TestFlight
   • Redesigned and optimized Instruments application
   • New SpriteKit and SceneKit design tools
   • Generation of all iOS launch images (at all supported resolutions)
   • New asset catalog support

What’s new For Enterprise-Focused Developers

Quietly, but steadily, Apple’s iOS platform has become the premiere mobile platform for enterprises. 98% of the Fortune 500 actively deploy iOS products within their mobile infrastructures. This trend has been no accident. Apple has continuously added robust and advanced enterprise support into the iOS platform. Comprehensive MDM support, enterprise single sign on, world-class internal and third-party data protection/encryption, and per-app VPN support are just several of Apple’s often-heralded enterprise features. Apple’s iOS 8 will help extend their enterprise lead. The platform will now include:

• Passcode-protection of all the major data types (Calendar, Contacts, Mail, Messages, Notes, Reminders) and third-party apps
• S/MIME controls per message
• VIP Threads to allow a user to subscribe to important email threads and get notifications on their lock screen, without having to designate the sender(s) as “VIPs”
• Optimized and enhanced email and calendar navigation and handling
• Easier access to corporate documents
• Enhanced MDM support.

However, this blog post is meant to have a development focus, so we have included a few of the new API’s that enterprise developers will love.

1. Local Authentication. Although this feature will be of interest to most mobile development teams that produces an app that includes user sign on, DSI expects that enterprise developers will quickly adopt this. On capable hardware – such as the iPhone 5s, iPhone 6 (rumored), iPad Air 2 (rumored), and the iPad Mini Retina 2 (rumored) – developers can now have access to Touch ID biometric fingerprint authentication from within apps. iOS 8 exposes a simple API that tells the host application whether the authentication succeeded or not. At no time does the host app have access to the user’s biometric information. In fact, Apple’s own applications cannot even access it. The user’s biometric information stays locked away in the processor’s secure enclave. Allowing Touch ID access will provide a greater level of security to third-party apps and allow for new authentication-based workflows to be created (including action sign off and approval scenarios).
2. Extensions / Notification Center Widgets / Interactive Notifications. These new features were covered above, but for enterprise developers we think they deserve to be called-out again. These three features will allow enterprise developers to create app and functionality suites that previously have only been available on desktop or web-based solutions. Each will allow strategic and secure access of critical line-of-business data and processes between applications, as well as lower the interface footprint for enterprise users that often have to focus on multiple tasks at a time. Additionally, all of these new extension points and notification actions can be configured and managed through the MDM interfaces.
3. Document Providers. Apple iOS does not have an exposed file system at the user-level. Although lamented by some, this sandboxed, security-focused limitation has made iOS very resistant against malware and other related breaches. Starting with iOS 8, Apple will allow applications to leverage third-party document providers. This new API will allow applications to access document-based assets (including JSON, Binary/BLOB, XML, or vendor formatted data) that reside on off-device services. The third-party document service providers – which will initially include Apple iCloud, Microsoft OneDrive, Box.net, WebDav, and Drop Box (rumored, but highly expected) – will register themselves directly with iOS. At runtime, iOS will dynamically extend your app’s sandbox security wall to include any selected document accessed from one of these services. When the document is no longer needed, the sandbox will automatically be constricted to no longer include the resource. All of the settings and permissions related to the document providers will be managed by the user at the iOS level. This new feature will allow enterprise apps (and consumer ones too) to securely and consistently source and share information through established document service providers with very little application overhead or management. This will open the door for new types of application workflows that allow mobile users to seamlessly access document-based data within iOS.

What’s new For Gaming And Media-Focused Developers

Not be left out, gaming and media-focused developed will find a plethora new features and APIs available in iOS 8. Like with the discussion of Xcode 6 above, it would impossible to do justice to all of the new options available (and it would be also be a bit out-of-focus with the rest of this blog post). However, for those interested, here is a quick rundown of the major new features iOS 8 provides for gaming and media-focused development teams:

• Metal API – This will provide low-level access to the device GPU that bypasses the normal application and driver stack often yielding 5-10x frame rendering speed improvements.
• Many new SpriteKit enhancements.
• New SceneKit SDK that will bring 3D rendering in a similar fashion as SpriteKit.
• New SpriteKit and SceneKit design and debugging tools.
• New non-destructive photo/video editing extensions.
• Manual control of camera settings (e.g. focus, white-balance, ISO, shutter speed).
• Full access to photo/video library regardless of device or iCloud source location.

Conclusion

DSI is excited about Apple’s iOS 8 feature and platform announcements. For over 20 years, DSI has been a pioneer in building mobile solutions for both the enterprise and consumer marketplaces. We have already started reworking our own Mobile Development Best Practices and our related technical skillsets to include iOS 8, Swift, and Xcode 6. If you have a mobile development team or a mobile-focused project, we would welcome the opportunity to talk to you and explore how Apple’s iOS 8 mobile platform can be leveraged and mastered.

Now, I could fill up this blog entry by rehashing Microsoft’s latest TechEd offerings, or I could just quote from a terrific summary…which is what I will do!  The following is an excerpt from Brett Howse’s blog post on AnandTech.com that highlights some of Microsoft’s TechEd NA 2014 themes and day-one content (full blog post here):

 

On Monday Microsoft kicked off TechEd North America 2014 in Houston. TechEd is the technology conference geared towards IT Professionals and Enterprise developers, and focuses on the tools, software, and services that many enterprises rely on for storage, databases, communication, and device management. Microsoft has a new slogan – Mobile First, Cloud First – and it showed in the keynote.

 

The opening keynote address was delivered by Brad Anderson, Corporate VP, Windows Server and System Center Program Management.

 

Microsoft has been building out its cloud platforms over the last several years, basically replicating almost all of their major on premise services with a hosted version as a service with Azure as the platform to power these services. The key message from TechEd 2014 is that the public cloud and private cloud hybrid model is no longer the forefront of IT, but the new center. Not a single on premise product announcement was made this year.

 

While the growth in hosted services has been huge over the last several years, not all services are replicated, and not all enterprises can or will embrace this model, but clearly Microsoft is hoping to move the conversation to a point where it’s difficult to not at least consider the cloud as an option, if not for core services, then at least for DR, single sign on, testing environments, and possibly special projects.

 

The first product announcement was ExpressRoute, which enables private connections between Azure datacenters and on premise servers, or at a co-location environment with one of the partners. Clearly network speed, latency, and security has always been a negative against hosted services, and this service is supposed to help bridge that gap. To enable ExpressRoute, Microsoft has partnered with several network and telecommunications companies – namely AT&T, British Telecoms, Equinix, Level 3, Telecity Group, and Verizon. Bandwidth at General Availability is 10 Mbps to 1 Gbps with connections to Network Service Providers, or 200 Mpbs to 10 Gbps if connected through an internet exchange provider. ExpressRoute can be used in conjunction with the newly announced compute intensive VMs offering up to 16 cores, 112 GB of RAM, and 40 Gbps networking.

 

The next service announced was Azure Files which is currently in preview. Azure Files is simply the ability to have a shared SMB connection as a service in Azure allowing sharing of a single file from multiple Virtual Machines and accessible with standard Windows APIs allowing applications expecting on premise servers to utilize Azure file storage without rewriting the application.

 

Azure also has a new Redis Cache Preview based on the open source Redis project as a key-value store, and also announced was a new API Management framework to allow a client facing experience to publish, document, and code sample APIs.

 

Antimalware software is now supported in Azure VMs, as well as additional security suites from Trend Micro and Symantec. Apparently this is one of the more popular requests, so Microsoft is taking the opportunity to check another box which may have prevented companies from migrating.

 

Azure Site Recovery is another new offering – Disaster Recovery as a service. Azure can now be a DR target for a company’s VMs. This is a huge offering for a couple of reasons. First – disaster recovery planning is difficult, and expensive. Keeping multiple datacenters open, with high speed links among them, and enough duplicate equipment running at both sites to handle the entire load if one site was to fail is costly in both manpower and equipment. Now, Azure can be the other site, reducing the requirements to have effective DR. Most enterprises reserve DR for mission critical applications, but having the unlimited compute power (well, only limited by budget) of a cloud platform will enable this for a greater array of applications. The second reason this is a big offering is that it allows enterprises to test the waters with Azure by configuring Site Recovery and doing a planned failover of some services easily. They can then evaluate the results of hosting that service in the cloud, and gracefully fail back if they deem it won’t work for their scenario, or they can leave it in Azure if it does.

 

Office 365 and specifically OneDrive for business now offers encrypted file storage. This is essential for many businesses to use any sort of cloud based file storage for regulatory or policy requirements.

 

Also discussed, SQL 2014 has a new online transaction processing engine called in-memory which offers 5 to 30 times performance increases over previous versions of SQL Server, without any application modification required. This is in addition to the AlwaysOn capability to have a duplicate SQL instance in the cloud as a backup copy to add to the existing failover capacity of private cloud SQL.

 

On the mobile front, Microsoft aptly discussed management of corporate data, Software as a Service, and Mobile Device Management (MDM) by using their recently announced Enterprise Mobility Suite which consists of three key pieces.

 

First up is authentication. Azure provides identity and access management with Azure Active Directory Premium. This can be used to grant users access to applications and data with single sign-on.

 

Second was data management. Though not a new feature, Azure Rights Management can be leveraged to embed the file capabilities into the file itself. It works with encryption to require the identity of the recipient of the file to be verified, and if found to be an authorized recipient, the file can be opened. The example given was if someone sent an email, but chose the wrong person to send it to. This protects the data inside the file.

 

Finally, the MDM is provided by Windows Intune, which will gain support for the Samsung KNOX platform. Intune will provide containers and wrappers for applications a corporation needs to protect.

 

Azure RemoteApp is also new. It’s a new version of the well-known Remote Desktop feature RemoteApp built to run on Azure. This allows LOB apps to be uploaded to Azure and deployed to clients from the cloud.

 

Microsoft is currently under pressure in the enterprise from many companies – Amazon with AWS, Google, Apple, Blackberry, Oracle, and VMware to name some of the larger ones. Today’s TechEd keynote is a response to that pressure with new ways to deal with existing infrastructure issues in the enterprise. Last year they announced they were migrating to a devices and services company away from the traditional software company they had been in the past. With the push of Azure as the basis of everything announced today, it’s clear they are working hard to fulfill the services side of that equation. Microsoft has the advantage in the push to public/private hybrid clouds by being the underlying provider of most of the services for many enterprises, and clearly that’s an advantage they are looking to exploit as the push to the cloud occurs.
