How to install apps on Xcode 6 iOS Simulator
The most common way to install an app in the iOS Simulator is to use Xcode to build and install it. If you have a simulator app bundle which was built by someone else (or archived), you can install it using simctl:
xcrun simctl install booted /path/to/your.appKeep in mind, of course, that these apps need to be iOS Simulator apps, not iOS Device apps.
The iOS simulator is a different compiled binary than the app that gets published on the app store.
If you don't have access to the project's source code or simulator binaries, you can't install it on your own simulator.
In Xcode 8.2, you can now drag an app onto a iOS Simulator window. See this blog: https://medium.com/@hollanderbart/new-features-in-xcode-8-2-simulator-fc64a4014a5f
