One: Simulator error

When I used Xcode7 to do the real machine test, I did not succeed for some time, found that when the simulator was chosen, there were a lot of strange character combinations in the back of the simulator.

Although not affect the operation, but the feeling is always uncomfortable, so found a very simple way to solve the problem, of course, you can also use the mouth of the silly way to uninstall Xcode reinstall, or there are other ways, but personally feel this method is simple

Here is the workaround:

Troubleshoot emulator problems

• 1. Open Xcode and run a project at random
• 2. Terminal input sudo killall-9 com.apple.CoreSimulator.CoreSimulatorService enter your computer password
• 3. Terminal input RM-RF ~/library/developer/coresimulator/devices
• 4: Completely exit Xcode, then open, and you'll find that it's been perfectly solved
