Your Xcode version may be too old for your iOS version

Question

I have updated my phone\'s OS version to iOS 14 and spent today updating Xcode to version 12, yet when I try to build my Flutter app on my iPhone 11 - iOS 14 through Android Stu

Answer 1

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/

2. ReOpen Xcode.
