Firstly, I believe this is not possible in iOS 16. This API introduced is only available for iOS 17 or later. Secondly, the custom color can be set the Info.plist. Do the following: <dict> ..... <key>CFBundleIcons</key> <dict> <key>CFBundlePrimaryIcon</key> <dict> <key>NSAppIconActionTintColorName</key> <string>ShortcutsForeground</string> <key>NSAppIconComplementingColorNames</key> <array> <string>ShortcutsBackground1</string> <string>ShortcutsBackground2</string> </array> </dict> </dict> </dict> Reference: https://developer.apple.com/forums/thread/732747

Did you fix it? Seeing the same error with Xcode 13

If that doesnt work, add the entitlement file from the demo project or something and I guess, you will be able to integrate shareplay and use it in RC. PS: Currently I am working on shareplay feature in Xcode 13 RC

They excluded it in iOS 15. Install iOS 15.1 beta in order to see that

No! As far as I tested, it is required to test it on an actual device!
