Same here. I've tried even with a blank boiler plate project and it still has the same issue. I'm on Version 15.0 beta 6 (15A5219j)

I had TMS-90683: Missing Purpose String in Info.plist - Your app's code references one or more APIs that access sensitive user data. The app's Info.plist file should contain a NSHealthShareUsageDescription key ITMS-90683: Missing Purpose String in Info.plist - Your app's code references one or more APIs that access sensitive user data. The app's Info.plist file should contain a NSHealthUpdateUsageDescription key ITMS-90683: Missing Purpose String in Info.plist - Your app's code references one or more APIs that access sensitive user data. The app's Info.plist file should contain a NSLocationWhenInUseUsageDescription key For me how I fixed it was I thought if each of the key's were necessary including these but I had more for things health and location related. Turns out I didn't need a key that was Privacy - Location Always Usage Description, I found any code related to requesting always access to it and deleted it. I resubmitted my app without changing anything regarding the above except for deleting the Location Always Usage Description key. So I'm not convinced that the error had to do with what it said it did.

I found a work around. When looking at a color you'd like to change to a custom color much like Color(literal). They've added a feature on the sidebar, it should be under color. I believe this is new and their solution.

What model did you buy?
