An iOS developer is a software developer who specializes in creating mobile apps powered explicitly by iOS.
iOS, of course, is the mobile operating system (OS) developed by Apple, Inc. to run on its hardware exclusively. It powers all Apple mobile devices, such as the iPhone and iPad Touch. It used to power the iPad before the device shifted to iPadOS in 2019.
An iOS developer is responsible for the design and code of the base app. Part of his or her task is to ensure the app maintains its quality throughout use. As such, he or she may need to fix bugs that may affect the app’s performance via updates.

An iOS developer should be proficient in two programming languages commonly used in iOS development—Swift or Objective-C and Cocoa Touch.
Swift is Apple’s primary iOS development language, which is a combination of C and Objective-C.
Additionally, an iOS developer must be familiar with various frameworks, including Core Animation and Core Data. Hiring managers also look for experience in threading and performance tuning.
