Undefined symbol _FSEventStream* in FileWatcher

[Texot]

I imported the HotReloading target in my project and it complains about these symbols' missing for both simulator and real device.

Undefined symbols for architecture x86_64:
  "_FSEventStreamScheduleWithRunLoop", referenced from:
      HotReloading.FileWatcher.init(root: Swift.String, callback: (__C.NSArray, Swift.String) -> ()) -> HotReloading.FileWatcher in HotReloading.o
  "_FSEventStreamCreate", referenced from:
      HotReloading.FileWatcher.init(root: Swift.String, callback: (__C.NSArray, Swift.String) -> ()) -> HotReloading.FileWatcher in HotReloading.o
  "_FSEventStreamStart", referenced from:
      HotReloading.FileWatcher.init(root: Swift.String, callback: (__C.NSArray, Swift.String) -> ()) -> HotReloading.FileWatcher in HotReloading.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

My project has some objc code, so I added the following to other linker flags. It worked

-Xlinker -undefined -Xlinker dynamic_lookup

if this is not an issue, please close this.

Hi, Good fix! What version of Xcode was this?

[Texot]

xcode 13.3 (13E113)

[John Holdsworth]

And it's working OK. Strange you got the error and were able to fix it. This "standalone" injection is quite new.

I found the fix from your advice here. Not sure if the same cause

[John Holdsworth]

-Xlinker -undefined -Xlinker dynamic_lookup is always a good fallback even if it gives you a warning. Thanks for reporting this, closing now.

[John Holdsworth]

I've updated the project README with your fix. Thanks!

Thank you for your help and this great tool
