My swift solution :

func passwordValidator(password: String) -> String {
    ((password.reduce(true) { $0 == true && ($1.isLetter || $1.isNumber) }) &&
        3..<20 ~= password.count &&
        (password.contains { $0.isLetter }) &&
        (password.contains { $0.isNumber })) ? "VALID" : "INVALID"
}

passwordValidator(password:"Username123!") // INVALID
passwordValidator(password:"123") // INVALID
passwordValidator(password:"Username123") // VALID
