Answer 1

Open Xcode .

In the menu bar, click Xcode -> Preferences .

Once in the Preferences screen, click the Components tab.

Now, Click the down arrow next to the desired Simulator.

You can also check the validity of having saved each simulator by checking the directory where your simulators save.

Additionally, check the box that says "Check for and Install updates automtically" to avoid more problems of this nature.
