A while loop accepts a condition and keeps executing its body code while the provided condition is true. If the condition is never false, the loop will keep running and the program will get stuck in an infinite loop

for \_ in 1...3 {
  print("Ole")
}
// print: Ole
// print: Ole
// print: Ole

for char in "supercalifragilistic" {
if char == "c" {
    break
  }
  print(char)
}
// print: s
// print: u
// print: p
// print: e
// print: r

for num in 0...5 {
  if num % 2 == 0 {
    continue
  }
  print(num)
}
// print: 1
// print: 3
// print: 5

The continue keyword will force the loop to continue for the next iteration

for char in "hehe" {
  print(char)
}
// print: h
// print: e
// print: h
// print: e

for oddNum in stride(from: 1, to: 5, by: 2) {
  print(oddNum)
}
// print: 1
// print: 3

let zeroToThree = 0...3
//zeroToThree: 0, 1, 2, 3
