Any idea why I may be now getting an error building (it says failed with errors actually).

It’s not project specific as I opened another project I’ve not worked on for a while and it’s the same message. I do know Xcode updated itself, and downloaded iOS18.4 since I last opened Fire the other day.

I’ve tried older builds and just tried the latest from firehose, all the same.

It looks like the longer crashes. fun.

What version of Xcode is this, the new 16.3? reproduced :(.

Apple Feedback **FB17105391** “Linker in Xcode 16.3 fails with assertion on Static Library that was handled fine previously.”

It seems any code that has Extension Classes (Categories, in Objective-C speak) fails to link; and theres a couple in libToffee.

Only workaround for now: keep using Xcode 16.2 or lower, while we investigate. ☹

Ok, thanks marc, at least you are aware of the issue. I can probably wait though at least I can revert should I need to.

Yeah, thanx! I’d probably have noticed myself, tomorrow ;).

A reminder that I should do more testing against beta builds of Xcode, aside from just importing the new SDKs. Apple often sneak in major changes in a .x release…

FWIW, this should be fixed for vNext, tomorrow.
