DUPLICATE: 33664759

Summary: 
When using any MKMapView-related API, it is unusable slow on the iOS 11 Simulator while it is working fine on iOS 10.x Simulators. 

Steps to Reproduce: 
1. Create a new blank project
2. Add an MKMapView to your initial VC via storyboard or code

Expected Results:
The map-view is rendered correctly, user-interaction is possible as it used to be.

Actual Results:
The map-view is rendered after 10-20 seconds, user-interaction is not possible until then. It looks like the UI-thread is blocked completely.

Version/Build:
Version 9.0 (9A235)

Configuration:
iOS 11 Simulator
Xcode 9
macOS 10.13
