While Loop - Swift Programming

A while loop repeats while its condition remains true.

Repeat while true

while_loop.swift

let limit = 
var value = 1
var total = 0

while value <= limit {
    total = total + value
    value = value + 1
}

print("limit=\(limit)")
print("total=\(total)")

let limit = 
var value = 1
var total = 0

while value <= limit {
    total = total + value
    value = value + 1
}

print("limit=\(limit)")
print("total=\(total)")

let limit = 
var value = 1
var total = 0

while value <= limit {
    total = total + value
    value = value + 1
}

print("limit=\(limit)")
print("total=\(total)")

while Use a `while` loop when the number of repetitions is controlled by changing state rather than by directly iterating over a collection.
