About Simulator

Simulator allows you to rapidly prototype and test builds of your app during the development process. Installed as part of the Xcode tools, Simulator runs on your Mac and behaves like a standard Mac app while simulating an iPhone, iPad, or Apple Watch environment. Think of the simulator as a preliminary testing tool to use before testing your app on an actual device.

Simulator enables you to simulate multiple iOS and watchOS devices running current and some legacy operating systems. Each combination of a simulated device and software version is considered its own simulation environment, independent of the others, with its own settings and files. These settings and files exist on every device you test within a simulation environment.
