Simulator in use

Xcode the Simulator can ' t be launched because it's already in use.

Today, using the simulator, when testing, suddenly, the simulator does not come up.

The first few times must restart the machine, then really can not stand, on the big God's answer!

Tip info: The Simulator can ' t be launched because it's already in use.

It probably means:

When using Simulatorrun project a sometimes prompted, usually another project B with simulator, and then you command+q back simulator,

However, it can sometimes cause project B to crash directly and put the project in the ' Debug ' state.

This time in item B menu product Stop project, other projects can use simulator.

But I had a project at the time. No other project has been opened.

Check the following, the solution is as follows:

1, exit the simulator;

2, forced to quit Xcode; (the key is this step)

3, restart Xcode;

Try it and you can use it.

Record, continue to work ...
