They cannot be directly used with the Appetize service, as that requires Intel executables. If the app you want to run on the Appetize service is not open source, and you have not developed it yourself (or otherwise obtained the rights for the source code) - you cannot use this method.ģ) The apps you download from the App Store are meant for execution on ARM CPUs. This requires you to have the source code for the app. However it does so not by emulating the ARM CPU of an iOS device, but instead works by running the Intel version of said apps natively on an Intel CPU - while providing a 'simulated' operating system that maps onto the browser.Ģ) The app bundle you need for the Appetize service is usually obtained by building the app for the Xcode Simulator. It allows you to run native mobile apps in the browser in order to provide apps demos, training, testing, etc. 1) The Appetize service is not an emulator.
