Overview
The iOS & iPadOS 14 SDK provides support to develop apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 14. The SDK comes bundled with Xcode 12 beta, available from the Mac App Store.

General
Known Issues
- Important: Updating to iOS & iPadOS 14 beta from previous versions of iOS & iPadOS might take significantly longer than expected. Data loss could occur if the update is interrupted. (59101197)
- macOS Big Sur 11 beta or Xcode 12 beta might be required to sync or update devices running iOS & iPadOS 14 beta.
Known Issues
- Apps using JSONKit might quit unexpectedly on launch. Some forks of JSONKit hardcode private pointer representation details which are subject to change. (60290929)
Workaround: Use NSJSONSerialization instead. - fstab has been removed. Filesystem contents outside of an app’s sandbox can no longer be used for validation. (61098152)
- Apps using the NativeScript framework might quit unexpectedly on launch. NativeScript performs an unsafe operation to determine if an arbitrary pointer is an Objective-C object pointer. You can temporarily work around this issue by using object_getClass(_
instead of reading the isa directly; however, this code should be updated to avoid checking if arbitrary pointers are Objective-C object pointers. (62913064)
Known Issues
- You might not be able to activate Siri or trigger the Accessibility Shortcut using Full Keyboard Access. (59607413)
- Non-hearing aid devices might unexpectedly appear in the Hearing Devices setting. (64213426)
New Features
- SKOverlay enables downloading an app without having to leave the current app. The overlay can also be tapped to view the app in the App Store. In an App Clip, SKOverlayenables users to download the corresponding full app from within the App Clip. (56886149)
- You can now manage subscriptions, test upgrades, downgrades, and cancellations, as well as reset the introductory offer eligibility for a test account, simply by tapping on your sandbox account in Settings. (57248908)
- Avoid calling the presentCodeRedemptionSheet() API until you’re able to create supported codes. (59351258)

Known Issues
- Replaying an ARKit ARSession using the new ARGeoTrackingConfiguration isn’t currently supported. (63249747)
New Features

- AVAssetDownloadTask options, AVAssetDownloadTaskMinimumRequiredPresentationSizeKey, and AVAssetDownloadTaskAllowHighDynamicRangeKeyare currently unavailable. (64000708)
