Swift Break Statement

In Swift, the break statement is used to immediately exit a loop, switch, or labeled statement. When executed, the break statement will terminate the nearest enclosing loop, switch, or labeled statement and continue executing the program from the next statement.

Syntax

The basic syntax of the break statement in Swift is as follows:

break

Example

Here is an example of using the break statement in a loop:

for i in 1...5 {
    if i == 3 {
        break
    }
    print(i)
}

// Output: 1 2

Output

In the above example, the loop executes five times, but when the value of i is 3, the break statement is executed, causing the loop to terminate. The output of the program is 1 2, which are the values of i before the loop was terminated.

Explanation

The break statement causes the nearest enclosing loop to terminate immediately. In the above example, the loop is terminated when the value of i is 3, and the program jumps to the next statement after the loop.

Use

The break statement is useful when you want to terminate a loop early, based on some condition. It can also be used to exit a switch statement or a labeled statement. The break statement can be used in conjunction with control statements like if, while, repeat-while, and switch.

Important Points

• The break statement is used to immediately exit a loop, switch, or labeled statement.
• When executed, the break statement will terminate the nearest enclosing loop, switch, or labeled statement.
• The break statement can be used in conjunction with control statements like if, while, repeat-while, and switch.

Summary

The break statement is an important control flow statement in Swift that allows you to immediately exit a loop, switch, or labeled statement. It can be used in conjunction with other control statements to provide powerful and flexible control flow in your programs.
