I’m having this same issue. I have a C++ project, and when I try to build with arm64 support, the app crashes on launch on an iPhone 7 Plus and an .
When I try to Launch the game on an iPhone 7 Plus, I get this error for dozens of libraries:
“file was built for archive which is not the architecture being linked”
LogPlayLevel: UnrealBuildTool:

I need this to work. I can’t move back to a Blueprint only project, I have code that needs to be in C++.
Will building the engine from source fix this issue? (I’d rather use the binary version of the Engine, but if compiling from source works, then I can do that)
