Flutter: Projetc not building on iOS Simulator

Question

Flutter app build fails for iOS Simulator even though it compiles successfully for Android Emulator, iOS and Android physical devices also running from command line iOS build is successful.

This issue appeared after upgrading the Flutter version to 2.8.1 from 2.5.3.

Previously, it was working fine.

Any help would be really appreciated. Thanks.

working fine in Android Studio or Simulator not in xcode – Coranto

Only Simulator is problematic. I am running from Android studio. Also, opened the project in the Xcode as well but Simulator was not showing up on the list. – Handicraftsman

Check the certificate in the keychain access, sometimes the certificate corrupts it self when you upgrade/update flutter. Remove it from the keychain, and make Xcode create a new one. – Hardee

I think, if it was a certificate issue then I would not able to build for a real iOS device, right? – Handicraftsman

Answer 1

May be this is a solution:

See 「build settings」 on XCode and change 「Supported platforms: iphoneos」 to 「Supported platforms: iOS」.

Robey

This fixed the problem. I also had to run sudo gem uninstall cocoapods && sudo gem install cocoapods and restart the IDE. – Handicraftsman

i am facing the same issue, but there is not Supported Platform in this section of my Xcode project. there is Targeted Device Families.. – Befall

Answer 2

This worked for me.

• in Xcode, Go to Product > Scheme > Edit Scheme.
• In the scheme editor, select the Run tab on the left.
• Ensure the Build Configuration is set to Debug. Release and Profile configurations are not suitable for simulator builds.
