"No such module 'Flutter'" Xcode error

Help
1

I encounter this error when opening AppDelegate in Xcode. It occurs in both newly created projects and the existing project I am working on, affecting Flutter versions 3.27 and 3.29.

I am using Xcode 16.2.

Strangely, I can build and run the app on a device, but editing AppDelegate is frustrating because of this error. Xcode displays only this error and does not analyze the rest of the code for other errors or warnings.

Additionally, if I remove import Flutter, Xcode starts analyzing the code properly and displays all errors caused by the removal of the Flutter import.

Iā€™ve tried to use this solution After updating to Xcode 16, I'm encountering a 'No such module 'Flutter'' error when trying to build for iOS Ā· Issue #155873 Ā· flutter/flutter Ā· GitHub, but it didnā€™t help.

Actually Iā€™ve managed to find solution: How to fix the ā€œmodule Flutter not foundā€ compiler error in Xcode | by Ademola (Fadumo) Babs-Samuel | Medium.

Flutter.xcframework should be manually added to Frameworks, Libraries, and Embedded Content and Xcode will start to recognize Flutter import.

I have no idea why newly created Flutter projects also has this problem.

I found one solution.
add header search paths for flutter, so that xcode can find the flutter module.

${PODS_ROOT}/Flutter
$(FLUTTER_ROOT)/.ios/Flutter
${PODS_ROOT}/../Flutter
