How To Be A Great iOS Developer in 2021

By

 An iOS developer creates, tests, and improves applications for Apple's iOS operating system that are in line with their company's or client's goals and standards. They must have a thorough understanding of iOS and how it interacts with various Apple devices such as the iPhone, iPad, Apple Watch, and Apple TV, as well as the ability to customize their apps to their firm's or client's needs.

While Android has a larger global market share, Apple today has 1 billion iPhones in use. All of these run on iOS. As a result, the demand for iOS developers who can design apps for these devices and sell them on the Apple App Store has skyrocketed in recent years.

Learn the following programming languages

Swift and Objective-C are the most common programming languages used by iOS developers.
Apple released Swift, a general-purpose compiled coding language, in 2014. It outperforms Objective-C in terms of type safety, security, and performance. Apps for iOS, macOS, watchOS, tvOS, and Linux can be created by Swift.
Swift is compatible with Objective-C, a general-purpose, object-oriented programming language based on C that incorporates OOP paradigms via object messaging. Prior to the introduction of Swift, Apple's primary programming language for iOS was Objective-C.
Swift is fast displacing Objective-C as the most popular programming language on Apple's platforms for app development.

Skills required

  • Networking
  • Spatial reasoning
  • Core Data
  • Design Guidelines
  • Grand Central Dispatch
  • Git and GitHub

There are several ways to become an iOS developer, and the skills or degrees required vary depending on the position.

Swift and Objective-C are two programming languages that must be learned. You'll need a Mac, and if you're working on an iOS, watchOS, or tvOS app, you'll also need one of those devices, according to Bohon. You can download and install Xcode, which will then install the Objective-C and Swift compiler (LLVM) on your Mac. When you open Xcode, you'll see options for starting projects in Swift or Objective-C.
