this is the packaged app.

Answer 1

When running on a real device most probably setting a valid development team , development/production certificates and provisioning profile should fix these types of problems .

You can create a valid development team in your Apple Project Account and set it in Xcode->YourProjectTarget->Signing Capabilities .

NOTE: To debug why app crashes on a real device and not on simulator I would try to create an archive and validate it. You should get more info about the problem at the archive or validation process.
