We have a game that it has a iOS and Mac version, currently it is on UE 4.27 and on every update from Mac OS or Xcode… is a headache to be able to build it again.
So there is any plans to be able to update the branch to the new version?

According to apple (Submit your iOS apps to the App Store - Apple Developer) they will allow iOS 17 updates until April 2025.
I don’t suspect any 4.27+ modifications a lot earlier than that. So the best you can do is to stick to iOS 17 for now. Just check the 4.27+ branch on github every now and then. Sometime next year it is pretty likely that a change will appear there that enables iOS 18 builds with Xcode 16 
but my problem is that I updated the MACOS version so I cannot build anymore because Xcode 15 is not supported
Anyone else ran in to this issue? Have also updated the MacOS version, which means I can’t drop back down to xCode 15 but 4.27+ doesn’t seem to build against it.
Hi, is it working now, I am planning to try this today (Feb 11, 2025)
Is it working for you with Xcode 16? Or are you also facing crashes due to failed VectorIntrinsics in the UnrealMathTest?

Hello,
I’m also stuck on the VectorIntrinsics error in the UnrealMathTest with Xcode 16.
Have you found a solution to this problem?
Any insights would be greatly appreciated.

Finally, I found this discussion on UDN, which mentions a fix introduced in UE5 (CL 17679918).
The solution is to modify UnrealMathSSE.h and UnrealMathNeon.h, specifically the VectorSinConstant values:
static const float a = 7.58946609f; // 16 * sqrtf(p)
static const float b = 1.63384342f; // (1 - p) / sqrtf(p)
After applying this change, my Cook process is now working fine.
Hope this helps!
