I'm an Android developer that is now migrating over to Flutter. My first app is good to go. Bought a Mac mini, paid my £70+ enrollment fee. And now... in the throws of the release process I get the message... Failed to create provisioning profile. There are no devices registered in your account on the developer website. Select a device run destination to have Xcode register it. Do I really need to go and fork out for an IPhone as well now??
