Testing your iOS apps on Simulators

The Apple iOS Simulator, which ships as part of Xcode, is a tool for developing and prototyping your mobile app. While the iOS Simulator can be used to test your app's basic behaviour, it is severely limited as a testing platform. In order to effectively test your app across real world scenarios, it is essential to use real mobile devices.

Real iOS Devices vs Simulator comparison

Use the differences between Simulator and physical devices to help you determine what features and functionality to test in Simulator and what to test on physical devices.
