错误：swift：15：28：条件绑定中的绑定值必须是可选类型

Error : swift:15:28: Bound value in a conditional binding must be of Optional type

推荐答案

是的，您的错误在xcode 6.1中如下

Yes your Error is below in xcode 6.1

由于 IF 有条件必须 Bool 返回类型，但在你的if条件中返回类型是 NSPredicate ，这样你得到错误 swift：条件绑定中的绑定值必须是可选类型，您可以解决如下。

This error is occurs because of IF conditional have to Bool return type, but in Your if condition Return type is NSPredicate , so that you got error swift: Bound value in a conditional binding must be of Optional type you can solve as below.

var phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
     if phoneTest.evaluateWithObject(value) {
              return (true, .NoError)
         }
             return (false, .PhoneNumber)
        }

Swift中的电子邮件验证。

func isValidEmail(testStr:String) -> Bool {
        print("validate emilId: \(testStr)")
        let emailRegEx = "^(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?(?:(?:(?:[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+(?:\\.[-A-Za-z0-9!#$%&’*+/=?^_'{|}~]+)*)|(?:\"(?:(?:(?:(?: )*(?:(?:[!#-Z^-~]|\\[|\\])|(?:\\\\(?:\\t|[ -~]))))+(?: )*)|(?: )+)\"))(?:@)(?:(?:(?:[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)(?:\\.[A-Za-z0-9](?:[-A-Za-z0-9]{0,61}[A-Za-z0-9])?)*)|(?:\\[(?:(?:(?:(?:(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))\\.){3}(?:[0-9]|(?:[1-9][0-9])|(?:1[0-9][0-9])|(?:2[0-4][0-9])|(?:25[0-5]))))|(?:(?:(?: )*[!-Z^-~])*(?: )*)|(?:[Vv][0-9A-Fa-f]+\\.[-A-Za-z0-9._~!$&'()*+,;=:]+))\\])))(?:(?:(?:(?: )*(?:(?:(?:\\t| )*\\r\\n)?(?:\\t| )+))+(?: )*)|(?: )+)?$"
        let emailTest = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
        let result = emailTest.evaluateWithObject(testStr)
        return result
    } 

使用电子邮件验证：

if isValidEmail("[e-mail]"){
        print("Validate EmailID")
    }
    else{
        print("invalide EmailID")
    }

Swift中的电话号码验证

func validate(value: String) -> Bool {
        let PHONE_REGEX = "^\\d{3}-\\d{3}-\\d{4}$"
        let phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
        let result =  phoneTest.evaluateWithObject(value)
        return result
    }
