When I open up an IOS simulator to launch my flutter apps, it fails. Before it used to work fine. I get the following error:
Xcode build done. 122.2s

I have the same issue, and I've fixed it by running two command.
Please try, hope it help.
flutter channel dev
flutter upgrade
Good luck!

Hi I have the following error trying to debug an ios simulator with flutter. I used the flutter doctor command and also flutter doctor -v but it tells me there is no error. I also tried doing a flutter clean and then flutter run but the error persists. Has someone else happened to? Beforehand thank you very much!

I've been going through an online tutorial where when I get to the point I integrate Firebase my iOS emulator stops working. It does before, but not after. Additionally, there are no problems in my project according to flutter doctor and it even shows the iOS emulator as a connected device.
Things I have tried:
put GoogleService-Info.plist where it belongs
flutter clean
flutter update
pod init
pod update
I've recreated the project several times to this point and still can't get past this point

My only thought is maybe if I use a different emulator, but it works up until emulator. I don't know.
If needed, I can try to restart the project again from scratch. Thanks!
please re-check your info.plist and your integration
if you checked everything is setup properly copy your lip and re integration your project and try again .. i think you misleading something
don't forget also check your packages versions
and try to rm your profile and re install
rm ios/Podfile

After wasting so many times, I found only following command in terminal under Project directory folder is worked for me
rm ios/Podfile && flutter build ios
When I run the command
flutter run

What could be the possible reason behind this and how one can solve this issue ?
Clean your build and rebuild the app that should solve the issue.
flutter clean
I'm trying to build the Flutter sample project on VS code, but got this messages... The sample is building and running fine on Android device, and I also tried running the sample with Android Studio on iOS simulator which is also fine. It just doesn't work on VS Code. Has anyone meet the same issue?

This is a new security measure in the Xcode build system.
You can go into details here : https://stackoverflow.com/a/39667628/6622328
For a quick fix, just clean the app before rebuilding it (flutter clean).
I suspect you don't have XCode installed, or have enabled your Runner project for your developer ID.
