Repeat loop in Swift
Dec 24, 2023
As we know we having for loop and while loop in swift for writing loops but also we have repeat loop.
In repeat loop the loop block will be execute at least once even condition get fails.
repeat {
print("block executed")
} while number > 0
/* Output will be
block executed
*/
In above example even condition is false but still block will be execute once because condition will be execute at the end of the repeat loop code.
Let’s have one more example
var number = 1
repeat {
print(number)
number += 1
} while number < 5
/* Output will be
1
2
3
4
*/
