You could use <a href="https://github.com/rmaddy/RMPhoneFormat" rel="nofollow">RMPhoneFormat</a> library for formatting phone numbers.
The formatting should replicate what you would see in the Contacts app for the same phone number.

Here is a Swift extension that formats strings into phone numbers for 10 digit numbers.

<pre><code>extension String { 
 public func toPhoneNumber() -&gt; String {
 return stringByReplacingOccurrencesOfString("(\\d{3})(\\d{3})(\\d+)", withString: "($1) $2-$3", options: .RegularExpressionSearch, range: nil)
 }
}
</code></pre>

For example:

<pre><code>let number = "1234567890"
let phone = number.toPhoneNumber()
print(phone)
// (123) 456-7890
</code></pre>

Updated to Swift 3.0:

<pre><code>extension String {
 public func toPhoneNumber() -&gt; String {
 return self.replacingOccurrences(of: "(\\d{3})(\\d{3})(\\d+)", with: "($1) $2-$3", options: .regularExpression, range: nil)

}

I used the <a href="https://github.com/Serheo/SHSPhoneComponent" rel="nofollow"><code>SHSPhoneNumberFormatter</code></a> to do this so I don't have to change the type or subclass my <code>UITextField</code>

To set it up:

<pre><code>let phoneNumberFormatter = SHSPhoneNumberFormatter()
phoneNumberFormatter.setDefaultOutputPattern("(###) ###-####")
</code></pre>

Listen for the <code>UITextFieldTextDidChangeNotification</code> and run the following:

<pre><code>let phoneDict = phoneNumberFormatter.valuesForString(phoneTextField.text) 
phoneTextField.text = phoneDict["text"] as? String
