My problem is that I don't get the option to download in the first place!

I have the same problem with a minimal HLS download SwiftUI test app on an M1 iMac, it's just the basic code from the "Media Programming Guide". The call to: let downloadSession = AVAssetDownloadURLSession(configuration: configuration, assetDownloadDelegate: self, delegateQueue: OperationQueue.main) is causing the following messages to appear in the console window: Background URLSession adopters are required to have com.apple.application-identifier entitlement. The same code in a command line app gives the following message: Background URLSession adopters are required to have a bundle identifier. If you are developing a daemon, please enable CREATE_INFOPLIST_SECTION_IN_BINARY build setting. There is a bundle identifier for the console app's project.
