Swift Do While With Code Examples

The answer to Swift Do While can be demonstrated utilizing examples on this article.

var x = 0; 
whereas x < 10 { 
    print "(x)" //prints x till x < 10 evaluates to false
    x = x + 1
}

The actual drawback Swift Do While might be fastened by using another approach, which is printed within the subsequent part together with some code samples for reference.

var counter = 0

whereas true {
    print("Counter is now (counter)")
    counter += 1

    if counter == 556 {
        break
    }
}
whereas (situation){
  // physique of loop
}

As we’ve seen, a variety of examples had been used to handle the Swift Do While drawback.
