objc-class-ref in ViewController.o

-[ViewController viewDidLoad] in ViewController.o

collect2: ld returned 1 exit status
I added corelocation.framework into frameworks folder of my project, the project is success on cleaning but failed and give the same three errors on building

Answer 1

You need to import Framework Which you have already done also add the following to your .h file where you are using the CLLocation class such as
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#interface UntitledViewController : UIViewController <CLLocationManagerDelegate> {
CLLocationManager* locationManager;
CLLocation* locationObject;
}
#end
Hope it helps!!

Answer 2

Removing and adding the framework back, is the correct solution.
Thank for the answer, it saved me a lot work.

Answer 3

Try adding this to your class
#import <CoreLocation/CoreLocation.h>

Answer 4

I was facing the same problem in my unit test project.
Problem was that I added CoreLocation.framework to my project but forget to add in unit test project.
