Swift - How to know when a loop has ended?

Question

Please, forgive me as i\'m very new to swift, and programming in general.

Believe me when I say I\'ve tried hard to understand this, but I simply ca

Here is the loop you tried to implement:

func loop() {
  for var i=0; i<5; i++ {
    println(i)
    println("loop has finished")
  }
}

The reason why "loop has finished" gets printed 5 times is because it is within the for-loop.

Anything in between your brackets will be run when the loop repeats (where I entered "enter code here)

for var i=0; i<5; i++ {
   enter code here
 }

The way that loops work is, it will repeat until the condition is completed: i.e. i<5. Your i variable starts at 0 as you stated in var i=0, and every time the loop repeats, this number increases by 1, as stated in i++

Once i is not less than 5 (i is equal to 5 or greater than 5), then the code following your for-loop will be run.

So if you put your println("loop has finished") right after the forloop, you know it will run when the loop is completed, like this:

func loop() {
  for var i=0; i<5; i++ {
    println(i)
  }
  println("loop has finished")
}
