You can use the iOS simulator to run apps directly from your macOS kernel and replicate the experience of your end-level users to a great extent. With the first stable version released in late 2003, Xcode Simulator helps you develop apps for the entire iOS ecosystem, including iOS, macOS, iPadOS, tvOS, and watchOS. Simply put, Simulator lets you mimic the user interface of a device for which you are developing an app. Keeping definitions in mind, you may ask how Xcode Simulator can help in your app development.

The Xcode Simulator app is an integral part of the Xcode environment. Writing, compiling, and debugging functionalities work seamlessly in the Xcode IDE. Xcode brings together every tool and functionality you need for app development - a build system, text editor, and compiler.

In the simplest analogy, you can use Xcode similar to a pen and paper to design, write, and develop apps for the iOS system. The IDE lets you use Command Line Tools (CLT), similar to a UNIX-style app development environment.
