exp bi and submitted that to the app store. Now when I run it via testflight, the app crashes on launch. How can I debug this?
My app works fine within Expo. I’ve run
I experience the same problem at the moment using exp build:ios. I had a working app at test flight made some minor changes and it started to crash when resubmitting the ipa. I have tried to go back to the version that worked but that file is failing now.
Has the introduction of expo 28 changed anything with the build process?
An advice to make the test procedure a little faster is to transfer the ipa file to your connected Iphone by dragging the file to the “On My Device” sidebar.
I have the same issue since yesterday, I tried everything it still crash also I undo all my work and build it again still getting crashes.
Any suggestions ?
Im experiencing the same thing atm, Im trying to debug app from TestFlight, and see the log in Device Manager in Xcode
I also tried to run the application in the simulator to debug the error and here is what i got
Jun 14 17:50:47 — ExpoKitApp: assertion failed: 16G29 15C107: libxpc.dylib + 72226 [EE650BC3-0539-32F0-9205-ECF6755E856F]: 0x7d

post a build id or a link to a build page for one of the builds where this happens

My app is also crashing on launch in the simulator after I run ‘exp build:ios -t simulator’.
I’ve been trying to figure out what is causing it, but it’s pretty frustrating. I’ve been trying to zero on in on something for like 5 hours. I did check the logs and get this:

How do I debug this what’s going on?
It looks like the first problem I had was due to my .babelrc. I had these presets:
"babel-preset-expo", "es2015", "es2017", "react", "stage-2", "flow" ]
looks like I can replace them all with just
Now I’m getting farther, and getting an error screen that says:
Unhandle JS Exception: Module AppRegistry is not a registered callable module
Which I’m told is a totally generic error
