iOS Development


iOS is Apple’s mobile OS that runs on an iPhone, iPad, iPod Touch hardware. Apple provides tools and resources for creating iOS apps and accessories for these devices. As an iOS developer, you can program in native languages such as Swift or Objective-C or build cross-platform native applications using React Native (JavaScript) or Xamarin (C# & F#).

Developer Requirements


To develop iOS apps, you need a Mac computer running the latest version of Xcode. Xcode is Apple’s IDE (Integrated Development Environment) for both Mac and iOS apps. Xcode is the graphical interface you’ll use to write iOS apps. Xcode includes the iOS SDK, tools, compilers, and frameworks you need specifically to design, develop, write code, and debug an app for iOS. For native mobile app development on iOS, Apple suggests using the modern Swift programming language.

It is important to note that Xcode only runs on Mac OS X and the only supported way to develop iOS apps.

iOS Software Development Kit (SDK)


Explore the tools, technologies, capabilities, and languages included in the iOS SDK that make app development possible. Some iOS SDK essentials are the Cocoa Touch frameworks that include the UIKit, GameKit, PushKit, Foundation Kit, and MapKit. These frameworks and others allow you manipulate the iPhone or iPad camera, add voice interaction using SiriKit, explore music with MusicKit, expand viewing and listening via AirPlay 2, and even add iMessage Business Chat to your application. iOS 11 added the power of machine learning with Core ML and augmented reality (AR) experiences with ARKit.

Prepare your development environment


  1. Download Xcode
  2. Launch Xcode and create a New Project
  3. Get familiar with Xcode
  4. Build and run your app using the built-in iOS Simulator app that’s included in Xcode. The iOS Simulator is a great way to see what your app will look like and you can interact with it as if you were on a real device. You can simulate your app on a variety of hardware types and iOS versions.
