For iOS development, Mac OS is necessary. To develop an iPhone or iPad app you require to first get a Mac with Intel-based processor running on Mac OS X version 10.8 or later. The cheapest option is to get the Mac Mini. The fundamental model of Mac mini has a 2.3GHz dual-core Intel Core i5 processor and 4GB memory. It is sufficient to work with the iOS development tool easily.

Xcode includes a built-in iPhone and iPad simulator. It allows you to quickly prototype and test builds of your app during the development procedure. It runs on your Mac and acts like a standard Mac app as simulating an iPhone, iPad, etc. It is a preliminary testing tool to use before testing your app on an actual device.
