Find number of spaces in a string in Swift

Question

What method do I call to find the number of spaces in a string in Swift? I want to loop through that number, something like this:

@IBOutlet weak var stack: U         


        

Answer 1

Another way could be the implementation of the following function :

func nbSpacesIn(_ word: String) -> Int {
return String(word.unicodeScalars.filter({$0.value == 32})).count}

Answer 2

let title = "A sample string to test with."
let count = title.componentsSeparatedByString(" ").count - 1
print(count) // 5

Answer 3

Swift 5 or later

In Swift 5 we can use the new Character properties isWhitespace and isNewline

let str = "Hello, playground. Hello, playground !!!"
let spaceCount = str.reduce(0) { $1.isWhitespace && !$1.isNewline ? $0 + 1 : $0 }
print(spaceCount) // 4

---

If your intent is to count " " only

let spaceCount = str.reduce(0) { $1 == " " ? $0 + 1 : $0 }
