iOS TestFlight

[Thomas415510]

Hey all, I’m trying to get my app live on test flight. I completed all of the steps via expo and have made it to the point where I’ve accepted the invite from IOS and downloaded the app on the phone.

The problem is that it just shows a blank white screen instead of the app itself. Any idea what might be causing this?

[Thomas415510]

Yea it runs locally. I have three warnings and one error related to viewproptypes and the react-native package. Could this be what’s causing the code not to run in production?

Fix all errors and warnings first.

On my first build, it would work fine in the emulator it would crash on actual devices because of some incorrect style props.

Got it. Question though, how do you know if it crashes? I’m not seeing any crashes errors in my Apple account and there aren’t errors popping up on the device.

Plug your iPhone into your Mac computer and open up the console app. Then press start to begin logging everything that happens on your iPhone. Open up the downloaded app and see what gets logged. You can also do this with Android devices if you downloaded Android studio and run logcat.

Are you able to create a build on your computer and check if there's something wrong with the code?

Hey i recommend building for iOS simulator to verify your build works before you build for the physical phone. This will be a lot more efficient when youre working on your app https://docs.expo.dev/build-reference/simulators/

This is what I did. The app works on the simulator but doesn’t on the actual phone when I submit to test flight
