When you're satisfied that your app is ready, you can launch it in the Simulator to test it.
Let’s take a closer look at the Build tab options:
Build and Run: Launches the app in the Simulator.
iPhone X: The default Simulator. Clicking here will reveal a dropdown list with all available simulators.
Project: Reveals a dropdown list where you can open the project folder or product folder, or open the product with Xcode.
Install: Installs the application on a connected device.
Select a Simulator on which to build and test your app, and press the Build and Run button.
