Swift had iterator-style loops from the beginning. It also initially supported C-style "for (i = 0; i < j; i++)" loops, but they were removed very early on (because in practice, they're rarely used for anything except iteration, and iterator-style loops are much more readable and less error-prone).
- jmnicolas 7y agoI never looked at Swift, but for example how do you wright 10 times "hello world" on the command line if you don't have for loops ? You could do it with a while loop (if it exists in Swift) but I'm at a loss as to why you would remove a for loop from a programming language.
- NobodyNada 7y agoIterator-style loops are much clearer and more concise in almost all cases. In this case you can iterate over a range: for i in 0..<10 { print(i) }
