问题
I'm trying to reset it. In Xcode 8 we went to "Simulator -> Reset Content and Settings". I don't see that in Xcode 9 and need to wipe my simulator.
回答1:
I found it. It is now under "Hardware -> Erase All Content and Settings"
回答2:
Xcode 9.4
You need to click on Simulator first. Hardware > Erase All Content and Settings. This will reset the simulator. Wait for a minute for the Simulator to rebuild.
