Starter is stuck on the splash screen

[hlandao]

Trying to run the starter from a clean state but it is not passing the splash screen.
Did anyone run into a similar issue?

@hlandao hey there! I have just cloned the starter and run it on simulator, everything works. And XCode logs don't seem to have any crucial errors 🤔 Could you share more information about the changes you've done to the code? Do you run it on a simulator or real device?
One issue that happens to me on the very first launch is that It shows error that it is not connected to Metro Bundle server but it goes after refreshing app by pressing R or just opening it again.

@kanzitelli thanks for the quick response. I was trying both on a simulator and a real device. I will try again and update quickly.

@kanzitelli Strangely cleaning derived data made the difference.
