Crash on press 'Start Unity' button
I am getting a crash on the press 'Start Unity' button.
2019-10-17 12:46:08.652612+0530 SwiftTuto[572:45459] *** Terminating app due to uncaught exception 'NSObjectNotAvailableException', reason: 'UIAlertView is deprecated and unavailable for UIScene based applications, please use UIAlertController!'
Does anyone have a solution for this?

The error is right there: 'UIAlertView is deprecated and unavailable for UIScene based applications, please use UIAlertController!'
If your Swift project uses 'UIAlertView', you need to change it for 'UIAlertController'. If your Unity project have a dependency that uses UIAlertView, maybe you need to contact the developer/support of that dependency.
