Swift While (Real-Life Examples)
Swift While (Real-Life Examples)
Use loops to retry operations, poll statuses, or process queues carefully with exit conditions.
While Loop from 3 to 1
Count down from 3 to 1.
Example
var remaining = 3
while remaining > 0 {
print("Remaining: \(remaining)")
remaining -= 1
}Poll Until Success
Repeat an action with a cap on attempts until a condition is met.
Example
var attempts = 0
var success = false
while !success && attempts < 5 {
attempts += 1
print("Checking... #\(attempts)")
if attempts == 3 {
success = true
print("Success!")
}
}
