@wanyangye @ImagineBoom I haven't had macOS 14.0 yet but I found this answer that you can try ti see if it works.

If it doesn't work, please confirm:

• Does the issue happen on a newly created Flutter project (counter app)?
• Please upgrade your Flutter SDK to the latest stable or master channel and retry to see if the result is different.

flutter channel master
flutter upgrade

• Please provide the entire output of flutter run -v on the reproducible sample code.

Thanks!

@wanyangye I notice this is indeed permission error on your output log (at flutterInfo.log) at #135199 (comment). I don't see the initial warning (at buildinfo.log) there, though.

@ImagineBoom I can see the same Warning on your output log (at flutterInfo2.log), the build is succeeded however.

Regarding the initial warning, I will label this for other's input.

I've retitled this to be about the error, since it was reported as a build error, and hidden the screenshot of the unrelated and harmless warning.

@ImagineBoom Please file a new issue about the warning you are seeing, since that's not related to the error.

[cbracken]

I ran across this in a couple Xcode/Sonoma betas. It disappeared for one developer beta (maybe the 6th beta), then reappeared in a later one. I can repro on last week's release candidates.

The warning reads as though part of the issue is a bug with Xcode incremental builds but I suspect it's likely that our build wiring is out-of-the-ordinary enough that we might be hitting some unusual edge-case.

In testing with a non-Flutter (AppKit/Swift) app, the same warning is emitted during commandline builds via xcodebuild build as well. Looks like there's a new Xcode release candidate a couple days ago; will try again with that and if I'm still seeing this, will file the bug with Apple, and see what's needed on our end to workaround (or suppress) the warning.

[cbracken]

After testing with Xcode Version 15.0 (15A240d), I'm still seeing this error both in Flutter and non-Flutter app builds that are built from the command-line.

its not work。I've followed the advice, and it's not working. I have just upgraded to MacOS14 Xcode15 to run the flutter project when this prompt appears, before the latest version of MacOS13 and the latest version of Xcode14, there is no problem.

[wanyangye]

I uninstalled Xcode 15 and used XCode 14.3 and now the flutter project is built properly.

Is flutter only supported up to 10.14? I need to be compatible with 10.13, is that OK?

OK, I have filed this issue #135277

Thanks!

@wanyangye the error you're experiencing is unrelated to the warning here

It's due to this error:

error: DT_TOOLCHAIN_DIR cannot be used to evaluate LD_RUNPATH_SEARCH_PATHS, use TOOLCHAIN_DIR instead (in target 'Runner' from project 'Runner')
error: DT_TOOLCHAIN_DIR cannot be used to evaluate LD_RUNPATH_SEARCH_PATHS, use TOOLCHAIN_DIR instead (in target 'Flutter Assemble' from project 'Runner')

error: DT_TOOLCHAIN_DIR cannot be used to evaluate LD_RUNPATH_SEARCH_PATHS, use TOOLCHAIN_DIR instead (in target 'Pods-Runner' from project 'Pods')

which was filed in: #132755
and was fixed in: #132803

This is caused by an issue in CocoaPods, which was fixed in: CocoaPods/CocoaPods#12009

However, as far as I'm aware, they haven't yet published a new release that includes their fix, so you'll need to rely on our workaround.

Please make sure you've got the latest Flutter version installed. You may need to switch master branch, but I believe this has been cherry-picked to stable (though not sure if we've published that stable version yet).

Closing as a duplicate of #132755.

[cbracken]

Is flutter only supported up to 10.14? I need to be compatible with 10.13, is that OK?

This is off-topic for this bug; however, you can see our Supported deployment platforms page for details. Short answer: 10.14 (Mojave) is the minimum required version today. This is because Flutter requires Metal support. If you need support for older versions of macOS, you'll need to use an older version of Flutter (and possibly older version of Xcode).
