MKMapRectMake in Swift causes linker error when compiling

Question

Using MKMapRectMake to create MKMapRect causes compiling error as below:

This is my code:

    var lat = 37.33072
    var lon = -122.029674
    var loc = CLLocationCoordinate2D(latitude: lat, longitude: lon)
    var point = MKMapPointForCoordinate(loc)

    var flyTo = MKMapRectMake(point.x, point.y, 0, 0);

and this is the error from the compiler:

Undefined symbols for architecture i386:
  "_MKMapPointMake", referenced from:
      _MKMapRectMake in ViewController.o
  "_MKMapSizeMake", referenced from:
      _MKMapRectMake in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

My work-around for this is create MKMapRect using the origin and size parameters. Note that I have added MKMapKit to the linked libraries in Build Phases

Is there anyone encounter the same issue and how you fix this?

Answer 1

Work around it with a utility function:

func myMKMapRect(x: Double, y:Double, w:Double, h:Double) -> MKMapRect {
    return MKMapRect(origin:MKMapPoint(x:x, y:y), size:MKMapSize(width:w, height:h))
}

And file a bug report with Apple, of course.
