I am adding a watch capability to an existing fairly complex Objective-C iOS application (that I have inherited), but am getting an unexpected build error right from the start.
ld: warning: directory not found for option '-L/Users/mac/Documents/raceQs-iOS/ios/raceqs_pod/Library' ld: warning: directory not found for option '-L/Users/mac/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Release-iphoneos' ld: warning: directory not found for option '-L/Users/mac/Documents/raceQs-iOS/ios/raceqs_pod/Pods/build/Debug-iphoneos' Undefined symbols for architecture arm64: "_OBJC_CLASS_$_WCSession", referenced from: objc-class-ref in MainClass.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
The error is generated when I add the following code to my Main class:
#import <WatchConnectivity/WatchConnectivity.h>
@interface MainClass ()<WCSessionDelegate>
@end
and
if ([WCSession isSupported]){
// WCSession *session = [WCSession defaultSession];
// session.delegate = self;
// [session activateSession];
}
I have researched the issue, and I think it's a problem with my build settings Library Search Paths which are:
Any suggestions would be gratefully received.
Fixed
Added WatchConnectivity.framework to Build Settings/Link Binary With Libraries
