The issue is dub. Make sure you are using the dub built for ARM.
What Apple does is if any program in the same process group is x86
specific, then all the executed programs that are universal (including
the linker) will switch to that mode.
The linker thinks you are building on x86, even though the compiler is
doing ARM64. I ran into this early on too. Switching to the dub that
ships with ldc built for ARM solved it!

So hard ..
Yeah, that's a known issue:

Try building with `-b plain` to avoid the debug build
