String Split in Swift in Swift

In Swift, you can split a string into an array of substrings using split(separator:). It takes a character as the delimiter:

s.split(separator: delimiter)   // splits using a delimiter character

Here are some examples:

let sentence = "hello world foo"
let words = sentence.split(separator: " ")
// words == ["hello", "world", "foo"]

let csv = "a,b,c"
let parts = csv.split(separator: ",")
// parts == ["a", "b", "c"]

You can loop through the resulting array:

for w in words {
    print(w)
}
