On the top left of xcode, next to the "play" and "stop" buttons there's a small drop down that allows you to select a device. This can be either a connected device, a "build only" device or a simulator. Select a simulator and hit the play button. You'll then have to wait a few minutes for the sim to start up after the build completes, it'll appear as a black screen with the apple icon on while it's starting up. Be patient with it! Once the simulator is running you can run and launch things much faster, but if you close the simulator you'll have to wait through the start up procedure again.
If your simulator is appearing massive or cut off you can change the size of the simulator by going to "window" > "scale" on the top menu.
