Control Flow and Loop in Swift : Swift tutorial

Example to use  if and switch to make conditionals, and use for-in, for, while, and do-while to make loops

let scores = [50 , 70, 80, 40,54, 44, 88]

var count = 0

for score in scores {

    if score < 50 {

        ++count

    }

}

print("You failed in \(count) subject")

Switch case:

let constand = "am swift"

switch constand {

case "objective c" :

    let result = "Am objecive C"

case let x where x.hasSuffix("swift"):

    let result = "ss\(x)ss"

default :

    let result = "Am not in this family."

}
