There used to be iOS simulators for Android, but they are no longer working.
While some of them are also available for Mac, and for online use. At the time of the writing, the emulators are largely available for Windows. This is to see whether or not the person who is willing to shift to iOS is comfortable enough with the iOS environment for not. The wonderful world of software has multitudes of iOS emulators that you can use to experience how iOS is. The good news is that you can somewhat experience how iOS works using an emulator.
