The GamePlay is very slow and laggy when running the build through any device in Xcode simulator
How to reproduce:
1. Download and open the attached project "LWRP_TEST.zip"
2. In "Player Settings" make sure that the "Target SDK" is set to "Simulator SDK"
3. Build the project with iOS platform
4. Run the project through Xcode and select any simulator device (i.e. iPhone Xr)
Expected result: Gameplay is running smoothly without lag (expected.mp4)
Actual result: the gameplay lags and is extremely slow (actual.mp4)
Reproducible with: 2018.4.2f1, 2019.1.8f1, 2019.2.0b6, 2019.3.0a6
