Hello!
Since Unreal Engine 5.7, after updating XCode and the IOS SDK, I can’t pack for IOS at all anymore.
Our team is using a Mac mini M4 (ARM64).
I was able to launch applications for IOS 18 in UE5.6.
The project DOES work, compile, build and run for Windows and Mac. The only failure is on IOS specifically.
The myriad of CPP compilation errors range from inculpating GENERATED_BODY to claiming there are missing .h files and missing modules, as if the engine forgot itself.
I have tried, after a full reset of the Mac, to use modern and legacy XCode in Unreal Engine, with and without Rosetta, installing the Metal toolchain, and every time I had the exact same amount of errors, no improvements or more mistakes.
Compiling from the IOS workspace yielded the exact same errors as well, around 380 of them.
Also seems like the IOS detection system in Unreal Engine 5.7 only works if launched with Rosetta.
Is there a known fix? A new workflow? Is this a compatibility issue that’ll be looked into as time passes?
