Flutter app, cannot build the app in simulator

Question

First time posting on stackoverflow. I feel like I'm entering into the "club" lol.

So I'm trying to launch this flutter app on iOS (app already on Google Play). But somehow, I can't run my app on my iOS Simulator, idk why.

• the first review of apple was about a crash happening when they try to do a selfie (as required in the app).
• flutter doctor is all OK

Here is what I obtain when I do flutter run output in my terminal:

Could not build the application for the simulator. Error launching application on iPhone 13.

Thanks for your help

Solution

1. Remove ios/Flutter/Flutter.podspec: rm ios/Flutter/Flutter.podspec
2. Run flutter clean
3. Run your app again.

If this doesnt solve the issue, try some solutions available here

Does this answer your question? error: 'Flutter/Flutter.h' file not found when flutter run on iOS

Thanks for the reply. I deleted the file, did flutter clean and ran the app, but unfortunately it didn't work. Same issue, same output + it regenerated the flutter.podspec file...
