I'm developing an app in Flutter. I tried to build the app, but I get the following error and can't run the app.

xcodebuild[80270:554507]  DVTAssertions: Warning in

I currently face the same issue. I can't run my Flutter app from IntelliJ on an iPhone 13 simulator. However, I'm able to run the app directly from XCode.

I tried to run flutter clean, but that didn't help.

@Olle Kyrychenko suggested the following steps in this post in case the Flutter app can't run on a simulator.

  1. rm ios/Podfile

Upgrade your packages:

  • pub upgrade
  • pub run

And update your podfile:

  • cd ios
  • pod update

Then clean and run:

  • flutter clean
  • flutter run

I haven't tested the above because I have some packages that can not be upgraded at the moment, but it might be the solution to the issue.

If I'll find something, I'll update my post.
