You can add @objc to Swift properties or methods to make them accessibile from Objective-C code. What does this exactly mean? I just want a one liner for this question.

The @objc attribute makes your Swift code available in Objective-C and the Objective-C runtime.

Explaination:

In some cases, you need finer grained control over how your Swift API is exposed to Objective-C. In that case, You can use the @objc(name) attribute to change the name of a class, property, method, enumeration type, or enumeration case declaration in your interface as it’s exposed to Objective-C code.

Check this: when to use @objc in swift code?

Most of the time it happens when you are sub classing a Swift class of Objective-C base class.The @objc attribute makes your Swift code available in Objective-C and the Objective-C runtime.
