Answer 1

func isValidPassword() -> Bool {
    // least one uppercase,
    // least one digit
    // least one lowercase
    // least one symbol
    //  min 8 characters total
    let password = self.trimmingCharacters(in: CharacterSet.whitespaces)
    let passwordRegx = "^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&<>*~:`-]).{8,}$"
    let passwordCheck = NSPredicate(format: "SELF MATCHES %@",passwordRegx)
    return passwordCheck.evaluate(with: password)
