Hi l am having a problem implementing google maps for iOS I have put all the relevant frameworks and added the -ObjC under Project NOt target and I am getting this error:

CoreData: warning: Unable to load class named 'GMSCacheProperty' for entity 'GMSCacheProperty'.  Class not found, using default NSManagedObject instead.
2015-02-09 22:48:01.326 AlertPoint[8038:957015] CoreData: warning: Unable to load class named 'GMSCachedObject' for entity 'GMSCachedObject'.  Class not found, using default NSManagedObject instead.

I have set the key and matched it to the bundle identifier as required and followed all the step, its been 3 days and No Luck. Please help.

You should add the @objc add to your NSManagedObject-class which you save in the CoreData:

@objc(GMSCacheProperty)
class GMSCacheProperty { 

}
