Area:
Xcode

Summary:
Constraints on any MKMapView in a storyboard appear not to be saved, and the map view moves to the upper left corner of the view and resizes to 1000 x 1000. Resizing the view in the Utility pane to something other than 1000 x 1000 allows the user to restore the constraints in the view to what they were when the project was saved.

Steps to Reproduce:
1) Create sample Single View iOS app.
2) Add MapKit framework to project.
3) Add MKMapView to storyboard.
4) Add leading, trailing, top and aspect ratio constraints
5) Build and run. A map appears in the view as expected.
6) Save project and close Xcode.
7) Open project in Xcode. The map view has resized to 1000 x 1000 and has moved to the upper left corner of the view it is in.
8) Change the size of the map view in the Utility pane to 100 x 100.
9) You should now be able to revert back to the constraints set in step 4.

Expected Results:
Steps 8 and 9 above should not be necessary, I should be able to open my project with constraints set as they were when I closed it.
