Debug a real device doesn't work, boots the app and freezes iOS 12.3

See original GitHub issue

Boot to a real device in debug mode doesn’t work, app freezes iOS 12.3

I have also tested this on a fresh install of react native and the issue still happens. When you build in Xcode 10.2.1 with the scheme set to the following (default)

Build Configuration: Debug Debug executable: ticked

The app will boot on to the device but not connect to the metro bundler. Then Metro bundler is there and boots up don’t change from this

When the app is installed on the device the splash screen shows and freezes. After about 3 / 5mins it will show you the first screen of the app it’s then frozen again. Finally, it crashes the app.

I have also built the app in Release and this is fine. Not really sure where to go from here?
