Coding SwiftUI course material in Xcode. Program is quitting and producing the message: Can’t open the application “SwiftfulSeries.app” because this application is not supported on this Mac." Any suggestions on how to solve this problem?
Where did you get SwiftfulSeries.app ?
Found solution - coding problem. Incorrectly trying to add background color to iPhone screen using background(Color.green). Changed code to Color(.green) and app runs. Very confusing error message.
