Working on a WatchOS app written in Swift, I recently got the following warning in Xcode:
Could not create compact unwind for [symbol]: stack subl instruction is too different from dwarf stack size
How can I fix or silence it?

Thanks to this discussion, I found the suggestion of setting the following linker flag:
LDFLAGS="-Wl,-no_compact_unwind"
Where does this go in Xcode? Select the target where you're getting the warning, and search for "linker" so that you can set Other Linker Flags to -Wl,-no_compact_unwind:
(This corresponds to the OTHER_LDFLAGS settings in the .pbxproj file.)
This silenced the warning for me. If anyone knows of a better way to fix or address the underlying issue, I'd love to hear it!
