  Phone number validation is kinda tricky thing, so I advise you to use some ready-to-use pod, like PhoneNumberKit instead of writing own ad-hoc validator.

Use this regular expression:

(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}

Code:

let phoneNumber = "+1 (123) 456-7890" //Replace it with the Phone number you want to validate

let range = NSRange(location: 0, length: phoneNumber.count)

let regex = try! NSRegularExpression(pattern: "(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}")

if regex.firstMatch(in: phoneNumber, options: , range: range) != nil{

    print("Phone number is valid")

}else{

    print("Phone number is not valid")

}

Use this regular expression

^[1{1}]\s\d{3}-\d{3}-\d{4}$

Use like this :

isValidMobile(testStr : "1 555-555-5555")

This will return true

isValidMobile(testStr : "1 555-555-55555")

This will return false

Function will be like this :

func isValidMobile(testStr:String) -> Bool {        

    let mobileRegEx = "^[1{1}]\s\d{3}-\d{3}-\d{4}$"

    let mobileTest = NSPredicate(format:"SELF MATCHES %@", mobileRegEx)

    return mobileTest.evaluate(with: testStr)

}

Use this regular expression

^[1{1}]\s\d{3}-\d{3}-\d{4}$

Use like this :

isValidMobile(testStr : "1 555-555-5555")

This will return true

isValidMobile(testStr : "1 555-555-55555")

This will return false

Function will be like this :

func isValidMobile(testStr:String) -> Bool {        

    let mobileRegEx = "^[1{1}]\s\d{3}-\d{3}-\d{4}$"

    let mobileTest = NSPredicate(format:"SELF MATCHES %@", mobileRegEx)

    return mobileTest.evaluate(with: testStr)

}
