Ld: Warning: Has Malformed Lc_Dysymtab

Working on building a react-native wrapper for the WireGuardKit library, but I'm having trouble getting it to work in a swift app for testing purposes. The library compiles, the app compiles, but when the library is linked, it throws this error:

ld: warning: '/Users/zach/Library/Developer/Xcode/DerivedData/vpn-testing-2-bwlltvgctdybzvheohentkkatmte/Build/Products/Debug-iphonesimulator/libwg-go.a[arm64][2](go.o)' has malformed LC_DYSYMTAB, expected 67 undefined symbols to start at index 4740, found 79 undefined symbols starting at index 15

I've tried installing different versions of go and trying to mess with build settings. Every time throws that error.

I ended up figuring out the solution to my problem after a few days. It was entirely due to the fact I was using the simulator built into Xcode and not a native device.

If you encounter this issue, just plug in an iPhone or other iOS device, then go to Product -> Destination and select the iOS device.

Doesn't hurt to clean (Cmd + Shift + K) before rebuilding.
