Swift – Infinite While Loop
To make a while loop run infinitely, the while loop condition has to be always true
. So, if we provide a boolean value of true
as condition, or a condition like 1 == 1
, that always evaluates to true, then while loop runs indefinitely.
Examples
In the following example, we take a while loop and give true
as condition.
main.swift
while true { print("Hello World") }
Output
Hello World Hello World Hello World Hello World Hello World Hello World Hello World ...
Now, in the following example, we take a condition that always evaluates to true in while loop, and make the loop run indefinitely.
main.swift
while 1 == 1 { print("Hello World") }
Output
Hello World Hello World Hello World Hello World Hello World Hello World Hello World ...
