Hmm, I have no idea what's going wrong there. It certainly is working on recent Macs (it is tested in CI).

To be honest this looks a lot like a bug in the SDK, or a version mismatch, but doesn't look like a bug in the Bluetooth package. From my experience the MacOS SDK often has weird problems like this. Perhaps you can try uninstalling the SDK and reinstalling it?

[ansoni-san]

What version of macOS are you on? And what version of Xcode?

[pronvis]

@ansoni-san

MacOS version: 13.4 xcode:

> xcode-select -v
xcode-select version 2397

@aykevl

"Perhaps you can try uninstalling the SDK and reinstalling it?" Did you mean reinstall xcode-select or Xcode itself? (or is it the same?)

[ansoni-san]

Try installing Xcode 13.4, and then use xcode-select to switch to that SDK.

That version of command line tools doesn't seem to match the build target correctly, or at least seems to misconfigure things.

[pronvis]

My Xcode is 14.3.1 version. I dont have another one. The path is:

> xcode-select -p
/Applications/Xcode.app/Contents/Developer

Which is the same as in Xcode:

[ansoni-san]

Yes the problem is your Xcode. It's too new and broken. You'll need a lower version I think 🤔

Or it may be fixed by changing your build to target the right minimum version of macOS based on whatever Apple has deprecated. In my experience this is usually caused by deprecations or API changes and your build targeting a particular minimum version of macOS.

These kinds of macros are usually controlled by macOS target version switches.

Honestly I would just install a lower version of Xcode that has good support everywhere, and be done with it. You should be able to install multiple versions side-by-side and switch between them as necessary (using xcode-select). 🙂

[pronvis]

Ohh... hate xcode :( Probably I will not continue with that process :)

[aykevl]

I don't have a lot of experience with macOS and Xcode, but using an older stable version seems like a reasonable things to try.

We will add support for XCode 14 only after GH actions adds support so we can test as part of our builds. Please see https://github.com/github/roadmap/issues/813
