I'm getting this error dyld: Symbol not found: _OBJC_CLASS_$_CLKFullColorImageProvider in watchOS 4 but not in watchOS 5, I believe it's related to my complication code below but can't figure out why...as far as I can tell the compiler shouldn't be looking for CLKFullColorImageProvider as I've blocked that off with if #available(watchOSApplicationExtension 5.0, *)

You and I encountered this issue at the same time. From this page:

Add ClockKit.framework as optional in the Link Binary With Libraries phase of your watch extension. This took care of my issue right away.
