Can you send us a bug report on this issue? This looks like a bug on the Unity side.

Please submit a bug report for this issue. It should not be happening.

Hello JoshPeterson,
Got the solution of the above issue.
If using .net 4.0 in Unity, append -DNET_4_0 to OTHER_CFLAGS

7

That is interesting. The generated Xcode project from Unity should already have that flag.

8

i got a Linker Command failed with exit code 1 (use -v to see invocation) error

9

Where can I find OTHER_CFLAGS?

EDIT: Got it. It’s within UnityConfig.xcconfig
