M1 Mac Xcode Build Done then Failed Flutter Project (apple silicon)

Question

I have been stuck on a problem that always occurs whenever I run any project from my M1 Mac. I have tried all the solutions from stack overflow and github. I am about to lose my. 4th project because of the hassle. First I thought it is because of flutter macOS desktop support. Disabled it, nothing changed. When I add some dependencies to my app and use it as a widget or function the project fails. It ruins my 4th day. I am sharing all the details and kindly waiting for your help.

Reproduced:

• Disabled macOS flutter desktop support
• delete podfile.lock and restart
• In Xcode Runner/Runner disabled for builds only
• Install cocoapods and ffi as it is (first answer) cocoapods_ffi
• Changed deployment target to 9 and 10

Solution

Add below code in the project pod file and run command pod install

post_install do |installer|
installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
    flutter_additional_ios_build_settings(target)
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
    config.build_settings["ONLY_ACTIVE_ARCH"] = "YES"
  end
end

end

It looks like the version of Flutter you're linking to is built for 'iOS Simulator-x86_64' and, of course, you're attempting to link that into an arm64 build. I have to admit to being ignorant as to whether Xcode can build iOS projects for the x86 simulator and launch them under Rosetta but it certainly can for macOS projects. Search your project settings for 'architectures' maybe?

[Muhtar]

I updated. Build arch doesnt contains x86_64 at all. I could not find what to do ? Do you have any idea because I am really stuck for decades

[Tommy]

If you can set the simulator build architecture to x86_64 then that might resolve the problem; apologies – I'm typing this from my work computer so can't check Xcode myself.

[Muhtar]

Where can I set it ?

[Tommy]

I'll see whether I can figure that out when I'm back at my personal machine. In the meantime, maybe try opening Xcode under Rosetta so that the whole suite is running as if on x86? beebom.com/force-apps-to-run-with-rosetta-m1-mac describes how.

[Muhtar]

Didnt help unfortunately

[L.Keysoft]

Facing the same issue, did you find a solution?

[Muhtar]

No solution for it unfortunatelly
