Swift Closure Functions Programs

In Swift programming language, a closure is a special type of function that does not have any function name. Like other function declarations, while declaring a closure function we don't use the func keyword. In other words, we can say that a closure is a self-contained block of the statements that can be passed around and be used in the program.

Syntax to declare a closure function:

{ (parameters) -> returnType in
   // statements

Where in is optional which is used to separate parameters or return types from the closure function statements.

This section contains solved Swift closure functions programs, practice these programs to learn the concept of closure, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Swift closure functions programs.
