I get this linker error when I attempt to build using xcode 7.3.1… do I need to update xcode? if so… what is the minimum version needed for Unity 5.6.x (i’m on 5.6.2p4)

invalid bitcode version 800.0.42.1_0

that is the producer version, the reader version was something like 703.xxxx

so… it seems that you can’t just “change” bitcode in xcode settings to NO, you have to use:

which seems odd… but now it is archiving.

WHY?
