[iOS] Frame rate caps at 30 if system time is moved backwards when application is running

Mobile

-

Reproduction steps:
1. Open the attached project.
2. Build and run it on an iOS device.
- Notice that application runs at ~60 FPS.
3. Minimize the application.
4. Go to "Settings > General > Date & Time".
5. Switch off "Set Automatically" if it's on.
6. Set time a few hours backward.
7. Maximize the application.

Actual behavior:
- FPS caps at 30.

Expected behavior:
- FPS caps at 60.

Notes:
- FPS moves back to 60 if the device screen is being touched.
- Not reproducible if time is changed prior to application launch.

Workaround:
1. Go to Classes/UnityAppController+Rendering.mm in trampoline (generated project).
2. Change the value of #define ENABLE_RUNLOOP_ACCEPT_INPUT from 1 to 0.
3. Build the XCode Project again.

Reproduced with:
iPhone 7+ iOS 11.1.1, iPad Mini 2 iOS 9.2.1, iPhone 6 iOS 10.3.3
2018.3.0a5, 2018.2.0f2, 2018.1.9f1, 2017.4.7f1
