Cant launch app in xcode

Hello, I am new to Xcode. When I try to run my app (just want to test something), I get this error message: Failed to install the requested application, The bundle identifier of the application could not be determined. I have the bundle id blank because I don't know what to put. Can someone please help, thanks in advance.

Blank? I'd expect Xcode to volunteer to do that for you...


What version Xcode? Auto or manual codesigning? Paid & active Developer Program account or Xcode's free provisioning?


BundleID docs are here, BTW: https://developer.apple.com/documentation/appstoreconnectapi/bundle_ids

In my case it was caused by missing files (missing files was red on list in xcode's file explorer).
