How do you validate an Australian phone number in Swift?

Question

I have implemented this nice solution provided by @Vasily-Bodnarchuk here

I'd like to amend this so I can validate Australian numbers. The problem is that the RegEx validation in the code below appears to only validate US numbers. I have tried a few different values but none seem to work.

Any ideas?

extension String {

    enum RegularExpressions: String {
        case phone = "^\\s*(?:\\+?(\\d{1,3}))?([-. (]*(\\d{3})[-. )]*)?((\\d{3})[-. ]*(\\d{2,4})(?:[-.x ]*(\\d+))?)\\s*$"
    }

    func isValid(regex: RegularExpressions) -> Bool {
        return isValid(regex: regex.rawValue)
    }

    func isValid(regex: String) -> Bool {
        let matches = range(of: regex, options: .regularExpression)
        return matches != nil
    }

    func onlyDigits() -> String {
        let filtredUnicodeScalars = unicodeScalars.filter{CharacterSet.decimalDigits.contains($0)}
        return String(String.UnicodeScalarView(filtredUnicodeScalars))
    }

    func makeAColl() {
        if isValid(regex: .phone) {
            if let url = URL(string: "tel://\(self.onlyDigits())"), UIApplication.shared.canOpenURL(url) {
                if #available(iOS 10, *) {
                    UIApplication.shared.open(url)
                } else {
                    UIApplication.shared.openURL(url)
                }
            }
        }
    }
}

There are a few 3rd party libraries that validate and format phone numbers of any country. Try searching for one of those. — rmaddy, May 07 '18 at 06:10

To validate an Australian phone use this:

var phoneExpression = "/^\({0,1}((0|\+61)(2|4|3|7|8)){0,1}\){0,1}(\ |-){0,1}[0-9]{2}(\ |-){0,1}[0-9]{2}(\ |-){0,1}[0-9]{1}(\ |-){0,1}[0-9]{3}$/"

// Valid
var phoneNumber1 = "0411 234 567"
var phoneNumber2 = "(02) 3892 1111"
var phoneNumber3 = "38921111"
var phoneNumber4 = "0411234567"

// Invalid
var phoneNumber5 = "3892 11"
var phoneNumber6 = "diane 0411 234 567"
var phoneNumber7 = "bob"

thanks, but I am getting a 'Invalid escape sequence in literal' error at every '\' – Roggie May 07 '18 at 07:14
replace each \ with \\ – Abdelahad Darwish May 07 '18 at 07:15
ok that got rid of the errors, but the 'isValid(regex: .phone)' is returning false. So the regex expression is not working. – Roggie May 07 '18 at 07:19
the regex worked without the first and last '/' forward slash. thanks for your help. – Roggie May 07 '18 at 07:28
good @Roggie you are welcome – Abdelahad Darwish May 07 '18 at 07:31
