I am not able to run my flutter app on iOS Simulator. It is giving me this error :

Launching lib/main.dart on iPhone XR in debug mode... Starting Xcode build... Xcode build done. 7.9s Failed to build iOS app Error output from Xcode build: ↳ ** BUILD FAILED **

Xcode's output: ↳ === BUILD TARGET url_launcher OF PROJECT Pods WITH CONFIGURATION Debug === /Users/snehal/.pub-cache/hosted/pub.dartlang.org/simple_permissions-0.1.9/ios/Classes/SwiftSimplePermissionsPlugin.swift:51:38: error: 'UIApplicationOpenSettingsURLString' has been renamed to 'UIApplication.openSettingsURLString' if let url = URL(string: UIApplicationOpenSettingsURLString) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ UIApplication.openSettingsURLString UIKit.UIApplicationOpenSettingsURLString:3:12: note: 'UIApplicationOpenSettingsURLString' was obsoleted in Swift 4.2 public let UIApplicationOpenSettingsURLString: String ^

Could not build the application for the simulator. Error launching application on iPhone XR.

Please Help. Thanks in advance :)

Open POD file in ios folder. Search 'SWIFT_VERSION' and change it to 4.2 ...like this

config.build_settings['SWIFT_VERSION'] = '4.2'

then do flutter run

Did you check flutter channel ?

Firstly, you should check after run flutter channel command in terminal.

then , you should change flutter channel as master with flutter channel master command.

Finally, restart IOS Simulator and run flutter in your application.

I hope that will be useful.
