SKAdNetwork

New Features

• Devices can now send install-validation postbacks to multiple ad networks that sign their ads using SKAdNetwork version 3.0. One ad network receives a postback with a did-win parameter value of true for the ad impression that wins the ad attribution.

Software Update

• You can now directly update your iOS or iPadOS device to the latest Release Candidate without removing the beta profile. After updating to the Release Candidate, you can choose to update to the next available beta or uninstall the profile to remove your device from the beta program. (66256273)

Xcode

Deprecations

• Don’t use the iOS MinimumOSVersion information property list key to declare the minimum release of macOS in which your app runs. Use LSMinimumSystemVersion instead. (73890473)
  • Future releases of macOS ignore the MinimumOSVersion key in Mac apps, including apps built with Mac Catalyst.
  • Future releases of macOS use the LSMinimumSystemVersion key in iOS apps built with Xcode 12.5 or later. If an iOS app doesn’t include an LSMinimumSystemVersion key, future releases of macOS compare the app’s MinimumOSVersion with the version of its Mac Catalyst runtime to determine compatibility.
