simulator hangs after running it for 2-3 times and when clicks on textfield.

I observed that simulator hangs when I clicks on textfiled after running the project on simulator 2-3 times. Then when I again run the project I am not able to perform any action. So I have to force quit the simulator and then it works. I am facing this issue after migrating to XCode 11. Please try to resolve the same ASAP.
