Discussion on: Daily Challenge #3 - Vowel Counter

[kesprit]

This is my solution in Swift (with an extension 😊) :

extension String {
    func numberOfVowels() -> Int {
        var count = 0
        let vowels: [Character] = ["a","e","i","o", "u", "y"]

        self.lowercased().forEach { char in
            if vowels.contains(char) {
                count += 1
            }
        }

        return count
    }
}
