Summary:
This is a duplicate of radar #33505938

If you open Maps.app (or an app that uses Google Maps) on the iOS simulator, the simulator performance seems to be just a few frames per second (around 1 or 2 frames per second). This was not the case in Xcode 9 beta 3.


Steps to Reproduce:
1. Open the Xcode 9 beta 4 simulator
2. Launch Maps.app
3. Pan around

Expected Results:
You get somewhere between 30 and 60fps on your macOS machine

Actual Results:
You get about 1 or 2 fps.

Version:
iOS 11.0 beta 4

Notes:
- This is not a problem in Xcode 9 beta 3
- This is a huge problem for us because we can't use the simulator anymore to test our app.
