MacOS Sequoia and Xcode 16 Errors

[Ben Cohen]

Hi All

I have upgraded my Mac to Sequoia and I am having issues compiling my ArchiCAD 27 addon.  (The 28 project is fine)

This is in Xcode 16, because older versions will not run on 15.3.

I thought maybe the 27.6003 DevKit upgrade may have had a fix but alas, no.

The error I am getting is this

“No member named 'GS_realloc' in namespace 'std'; did you mean simply 'GS_realloc’?”

I get this error on my project and also any example project

I have tried opening projects in Xcode 15 via terminal and it crashes

I have tried setting the deployment target to 10.5

Nothing is working.

If anyone can help, it would be greatly appreciated… 🙏
