I can't reproduce this and from the message about the stale precompiled header it doesn't seem like a gomobile issue. Can you build and run Objective-C apps from Xcode?

FWIW, https://stackoverflow.com/questions/19391768/file-has-been-modified-since-the-precompiled-header-was-built suggests cleaning the precompiled header cache.

Yes.

Removing that directory didn't solve this problem...

Ah, it looks like removing /var/folders/7t/qw3np69559591s1v0mk5_p1m0000gn/C/org.llvm.clang.hajimehoshi/ModuleCache solved this problem. gomobile bind succeeded after that. Thank you!
