Game Center

Game Center Sandbox Update

At WWDC 2015 we announced that the Game Center development sandbox environment would be turned off to simplify game development and beta testing. Starting today, the sandbox will no longer be available and all versions of iOS and OS X will automatically switch over to the production environment for development testing.

To learn more, read Game Center: Life without a Sandbox or visit the developer forums.

App Slicing Currently Unavailable

App slicing is currently unavailable for iOS 9 apps due to an issue affecting iCloud backups created from iOS 9 where some apps from the App Store would only restore to the same model of iOS device.

When a customer downloads your iOS 9 app, they will get the Universal version of your app, rather than the variant specific for their device type. TestFlight will continue to deliver variants for your internal testers. App slicing will be reenabled with a future software update. No action is needed by you at this time.

Xcode 7

Validating Your Version of Xcode

We recently removed apps from the App Store that were built with a counterfeit version of Xcode which had the potential to cause harm to customers. You should always download Xcode directly from the Mac App Store, or from the Apple Developer website, and leave Gatekeeper enabled on all your systems to protect against tampered software.

When you download Xcode from the Mac App Store, OS X automatically checks the code signature for Xcode and validates that it is code signed by Apple. When you download Xcode from the Apple Developer website, the code signature is also automatically checked and validated by default as long as you have not disabled Gatekeeper.

Whether you downloaded Xcode from Apple or received Xcode from another source, such as a USB or Thunderbolt disk, or over a local network, you can easily verify the integrity of your copy of Xcode.

Preparing for On-Demand Resources

If you’re using on-demand resources in your iOS 9 app, please note the following as you prepare your app for submission.

Make sure your code checks for on-demand resource asset packs as part of your standard code path and uses NSBundleResourceRequest to manually download the content if it is not present. This is important as there is a known issue that may cause initial and pre-fetch on-demand content to not download automatically.

On-demand resource asset packs that are added or changed as part of an app update are currently inaccessible. Be sure to include new or updated asset packs in your application bundle during your app update submission.

These issues will be resolved in a future iOS update.


Introducing tvOS

With the new Apple TV, you can deliver highly immersive apps on the big screen using the tvOS SDK. The SDK includes many of the same frameworks and technologies as iOS, such as Metal, UIKit, CloudKit, and Game Center, so you can leverage your existing code to create rich games and apps that look amazing on the new Apple TV. Get started with the tvOS SDK.

Xcode 7

GM Seeds Now Available

The next release of watchOS, iOS, and OS X will soon be in the hands of hundreds of millions of customers around the world. Make sure your apps are optimized for the exciting new features now available for these platforms.

3D Touch

Get Your Apps Ready for 3D Touch

Learn more about 3D Touch.


Supporting IPv6 in iOS 9

At WWDC 2015 we announced that iOS 9 will support IPv6-only network services. All apps submitted to the App Store must support IPv6 starting in early 2016. To make sure your app is compatible, use the networking frameworks (e.g., “NSURLSession”), avoid use of IPv4-specific APIs, and avoid hard-coded IP addresses. Before submitting your app, test for compatibility.

To learn more, read Supporting IPv6 DNS64/NAT64 Networks and watch Your App and Next Generation Networks.

iOS 8

64-bit Requirement for App Updates

As a reminder, beginning June 1, 2015 app updates submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code. For more information, read the 64-Bit Transition Guide for Cocoa Touch.

The enhanced Organizer window makes it easy to triage your crashes, jump directly to the offending code, and mark a crash as resolved. Learn more by reading Crashes Organizer Help.

Mac Apps That Use Garbage Collection Must Move to ARC

Mac Apps That Use Garbage Collection Must Move to ARC

Beginning May 1, 2015, new Mac apps and app updates submitted to the Mac App Store may no longer use garbage collection, which was deprecated in OS X Mountain Lion. Instead, migrate your apps to Automatic Reference Counting, using the migration assistant in Xcode to help with this transition. Apps may continue to use retain/release for manual memory management. For more information, read the Transitioning to ARC Release Notes.

Now Accepting Larger Binaries

The size limit of an app package submitted through iTunes Connect has increased from 2 GB to 4 GB, so you can include more media in your submission and provide a more complete, rich user experience upon installation. Please keep in mind that this change does not affect the cellular network delivery size limit of 100 MB.

Update to the Apple Push Notification Service

The Apple Push Notification service will be updated and changes to your servers may be required to remain compatible.

In order to protect our users against a recently discovered security issue with SSL version 3.0 the Apple Push Notification server will remove support for SSL 3.0 on Wednesday, October 29. Providers using only SSL 3.0 will need to support TLS as soon as possible to ensure the Apple Push Notification service continues to perform as expected. Providers that support both TLS and SSL 3.0 will not be affected and require no changes.

To check for compatibility, we have already disabled SSL 3.0 on the Provider Communication interface in the development environment only. Developers can immediately test in this development environment to make sure push notifications can be sent to applications.
