Your Xcode version may be too old for your iOS version


xcode flutter dart ios14

This is what I did:

  1. Updated Xcode
  2. flutter clean on the terminal.
  3. flutter upgrade on the terminal.
  4. Open Xcode and run the application once.
  5. flutter clean again.
  6. flutter run.

It should work now.

This problem is somewhat confusing, I got the same error with Xcode 12.0.1 and iOS 14.2 beta.This solved for me

Download Device support files of iOS 14.0 from this link.

for iOS 14.2 beta there is a pull request that is not yet merged

  1. Unzip and Paste it in this location. /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/

hierarchy

  1. ReOpen Xcode.

This issued was raised a while back in August in the flutter repo. Currently, the issue has been fixed by the recent flutter update.

Run flutter upgrade to v1.20.4 to get the fix
