Testing your iOS apps on Simulators

Simulator is great for rapid development of your iOS app allowing you to see the results of changes quickly, debug errors, and run tests. It is also important to test your app on physical devices as there are hardware and API differences between a simulated device and a physical one. Simulator is an app running on a Mac and has access to the computer’s resources. These resources are likely to be different on a real mobile device.

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.
