Note: The flutter iOS SDK only runs on 64-bit devices. If you build your app with 32-bit support, check the device's architecture before using this API. this affects most simulators but not devices in current usage
Close your XCode if your project is open and from the terminal, navigate to the iOS folder in the flutter project and run
If it wasn't present before, once done this will create a <Your Project>.xcworkspace open this in XCode .
That's it IOS is ready
To resolve this remove the line
In your project's (not target) as shown below
XCODE project's configuration.
That's it. iOS is done!
