iOS Simulator build fails – ffmpegkit.framework missing arm64-simulator slice (Xcode 26+)

[blacknight9]

Problem

Building Flutter app for iOS Simulator fails on Apple Silicon Macs.

Xcode error:
Building for 'iOS-simulator', but linking in dylib built for 'iOS'

ld: building for iOS Simulator, but linking in ffmpegkit.framework built for iOS device only

Cause

The ffmpegkit.framework only includes iphoneos architectures and does not include:

• arm64-simulator
• iphonesimulator slices

Xcode 26+ requires arm64 for simulator builds, so the framework cannot link.

Environment

• macOS: Apple Silicon (M-series)
• Xcode: 26+
• Flutter: latest
• Plugin version: 4.1.0
• Target: iOS Simulator

Expected

Plugin should ship:

• XCFramework OR
• universal framework including iphonesimulator arm64

Actual

Build fails for simulator.

Request

Please provide an XCFramework with arm64-simulator support or clarify if the project is no longer maintained.

I think this problem occurs afterpgrade Flutter to 3.41.0.

Try `flutter pub outdated` for more information.
The following plugin(s) are excluding the arm64 architecture, which is a requirement for Xcode 26+:
  - ffmpeg_kit_flutter_new_min_gpl
Consider installing the "Universal" Xcode or file an issue with the plugin(s) to support arm64.

Solution to this?

Builds work fine since Flutter 3.41.4 if you build for "universal" simulator and exclude arm64 config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" in Podfile

[PhantomRay]

Upgrade to 3.41.4 automatically fixed it.
