How do you stop a while loop in Swift?

The loop will first execute the body, then check the condition, and, while it’s truthy, execute it again and again. For example: let i = 0; do { alert( i ); i++; } while (i < 3); This form of syntax should only be used when you want the body of the loop to execute at least once regardless of the condition being truthy.

Swift – Break Statement

Swift while loop is used to run a specific code until a certain condition is met . The syntax of while loop is: while (condition){ // body of loop } Here, A while loop evaluates condition inside the parenthesis () . If condition evaluates to true , the code inside the while loop is executed.

The repeat-while loop will execute the statements at least once even if the defined condition fails (FALSE) because it will execute the statements first then it will perform condition check but in while statements execution will perform only when the defined condition is TRUE.
