Thanks for the answer! As I understand, you are partially correct. playbackState is available for MacOS but also for CarPlay implementation. Only by using playbackState I got correct behaviour with CarPlay on simulator. I'm talking about synchronisation of playback state on CarPlay system and on a phone/pad. OK, if error caused by misalignment between provisioning profile and list of entitlements, could you/anyone tell me how to extend a profile to support additional entitlements?

While an implementing a CarPlay functionality I also faced with similar issue. Correct work for CarPlay requires an entitlement "com.apple.developer.playable-content". Without it an application doesn't show an icon in CarPlay and all corresponding functionality (NowPlayingInfo) became broken. Problem is also described here: https://blog.fethica.com/add-carplay-support-to-swiftradio/ And in an issue: https://github.com/analogcode/Swift-Radio-Pro/issues/104#issuecomment-433407949 Looks like need to: apply for CarPlay functionality at https://developer.apple.com/contact/carplay/ , but looks like this page isn't available for free and need to purchase Apple Developer Program. Really sad for a spending 99$ :(
