When developing for iOS devices, most developers use the official Xcode tool. The problem is that image design and development managers are not necessarily familiar with xcode operations, when Ios-sim is a solution.
Once a friend of iOS development, I believe that it will be very troublesome if you want to compile the program to iOS and distribute it to other people on the computer without the App Store. Ios-sim is an open source software that executes on Mac OS X to allow non-developers, such as graphic designers and managers, to execute programs that were originally compiled for iOS and placed on iOS emulators. Ios-sim is a program that executes on a terminal, specifying the iOS application as a parameter when executing ios-sim. When finished, the program is automatically installed on the iOS emulator and is ready to be used. The version of the SDK can also be specified when executing Ios-sim, or it can be specified only on Iphone/ipad. The ability to quickly identify the SDK version is also useful for developers.
