But Swift exceeds the ability to catch software bugs. Some core concepts in Swift are the same as in Objective-C, such as dynamic dispatch, extensible programming, and late binding. It works for iOS, macOS, tvOS, and watchOS. Swift was released back in 2014, and developers are still getting used to it. Swift is a newer programming language developed by Apple. There are a lot of established good case practices or coding rules that you need to follow while writing code in Objective-C - for example, using camel case notation while writing commands.

If you haven’t used Objective-C before but are familiar with some object-oriented languages like C# or Java, then it would be relatively easy for you to learn. Being familiar with Xcode is a prerequisite to using Objective-C since it is the Integrated Development Environment (IDE) you’ll be building in. Using Objective-C means that you’ll get language-level support for your object-graph management and object literals.

Objects are at the core of building any IOS or OS X application. It is older than Swift and offers dynamic runtime and object-oriented functionalities.

Objective-C was introduced in 1984 and used to be the main programming language for iOS and Apple OS X.
