I’m working on a Flutter project, and I’m encountering a Swift Compiler Error when trying to run my app on the iOS simulator. Here’s the error message I’m getting:
Swift Compiler Error (Xcode): Method does not override any method from its superclass
/Users/User/.pub-cache/hosted/pub.dev/flutter_inappwebview-5.8.0/ios/Classes/InAppWebView/InAppWebView.swift:1225:25
I am able to run other projects so the problem is not with configurations.
My pubspec.yaml Includes:
dependencies:
url_launcher: ^6.2.5
youtube_player_flutter: ^8.1.2
url_launcher_ios: ^6.2.4
What I've Tried:
- Updating youtube_player_flutter and url_launcher_ios to their latest versions.
- Cleaning and rebuilding the project using:
flutter pub upgrade --major-versions
- Checking if flutter_inappwebview is directly listed in my pubspec.yaml. It’s not there, but it seems to be included as a transitive dependency.
my Xcode version is Version 16.1 (16B40)
in my pub get outdated
