title: Can't run Flutter app on iOS without usb-cable connected
body: <p>I have a Flutter project which shows a map with a user's location.</p>
  <p>This app runs fine on physical Android and iOS devices when connected via USB.</p>
  <p>Without having the USB cable connected on iOS, the app crashes immediately when started. On Android this not an issue.</p>
  <p>Other apps I've made in Ionic/Angular did not have this problem. Could it be that there is some debugger in XCode to which my app tries to connect? Or maybe another setting I've missed?</p>
