iOS 9 Hidden Features

Apple just released iOS 9.0.2, the latest public release for consumers, but it also has a treat for developers. The company released iOS 9.1 beta 3 on Wednesday, which includes several changes.

In its release notes, Apple highlighted known issues related to Siri, Settings, UIKit, Podcasts and Restore, but said it also fixed some issues from earlier betas, like issues with two-factor authentication for iCloud logins. Otherwise, iOS 9.1 is the release that will deliver new Emoji and other features, like eventual support for Apple Pencil on the iPad Pro.

Developers should find the update in the Apple Developer portal now. Here’s a look at the release notes:

Introduction
iOS SDK 9.1 beta 3 provides support for developing iOS apps. It is packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.

With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 9. You can also test your apps using the included Simulator, which supports iOS 9. iOS SDK 9.1 requires a Mac computer running OS X v10.10.3 (Yosemite) or later.

This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.

Bug Reporting
For issues not mentioned in the Notes and Known Issues section, please file bugs through the Apple Developer website (https://developer.apple.com/bug-reporting/ios/). Additionally, you may discuss these issues and iOS SDK 9.1 in the Apple Developer Forums: https://forums.developer.apple.com/community/pre-release/ios-9-beta. To get more information about iCloud for Developers, go to http://developer.apple.com/icloud.

Autosubmission of Diagnostic and Usage Data
By default, the iOS 9.1 beta automatically sends anonymous diagnostic and usage data back to Apple. This includes information about crashes, freezes, kernel panics, and information about how you use Apple and third-party software, hardware, and services. This information is used to help Apple improve the quality and performance of its products and services. You can stop autosubmission of diagnostics and usage data by going to Settings > Privacy > Diagnostics and Usage > Don’t Send.

Notes and Known Issues
Apple ID
Known Issue
If you sign in with different Apple IDs for iCloud and iTunes during Setup Assistant, it may hang.

Workaround: Do not use different Apple IDs for iCloud and iTunes during Setup Assistant. After setup, sign in by going to Settings > App and iTunes Stores.

iCloud Keychain
Note
During the iOS 9.1 beta, iCloud Keychain accounts with two-factor authentication enabled will use beta servers. If you do not want your iCloud Keychain data stored on beta servers, do not use the beta software.

Fixed in Beta 3
If you disable two-factor authentication on your iCloud account, your iCloud Keychain may also get turned off.
Workaround: Confirm that iCloud Keychain is still on in Settings after disabling two-factor authentication.

When activating iCloud Keychain in Settings on iPad, you may be unable to complete the activation.
Known Issue
Sometimes while setting up iCloud Keychain, you receive a “Could Not Set Up iCloud Keychain” error.

Workaround: Reboot the device.

Metal
Note
For tvOS Metal development, it is required that you use the tvOS-specific feature set enum MTLFeatureSet_TVOS_GPUFamily1_v1.

PhotoKit
Known Issue
If your app gets the gesture recognizer from the PHLivePhotoView object (via playbackGestureRecognizer) to install it on a different view, subsequently setting a new value for livePhoto on the PHLivePhotoView object causes it to reinstall the gesture recognizer on itself.

Workaround: Your app can get the gesture recognizer and reinstall it on the appropriate view every time after setting a value for livePhoto.

Podcasts
Fixed in Beta 3
The sleep timer does not work in this beta.

Restore
Fixed in Beta 3
If you’ve set a region that doesn’t match your language, restores from iCloud Backup might not progress.

Workaround: During restore, change your region to match your language. You can change it back after the restore is over.

Known Issue
Sometimes while restoring from iCloud backup, you will not see your list of backups, if you have two-factor authentication enabled on your iCloud account.

Settings
Known Issue
Settings may become unresponsive after signing into an iMessage or FaceTime account.

Workaround: Quit Settings from the App Switcher.

Siri
Known Issue
When asking Siri to play music, Siri will return an error but will still play back the music requested.

UIKit
Note
On 3D Touch capable devices, touch pressure changes cause touchesMoved:withEvent: to be called for all apps running on iOS 9.0. When running iOS 9.1, the method is called only for apps linked with the iOS 9.0 (or later) SDK.

Apps should be prepared to receive touch move events with no change in the x/y coordinates.
