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)
 }
}
</code></pre>

I would do this way:

Example:

<pre><code> NSMutableString *stringts = [NSMutableString stringWithString:self.ts.text];
 [stringts insertString:@"(" atIndex:0];
 [stringts insertString:@")" atIndex:4];
 [stringts insertString:@"-" atIndex:5];
 [stringts insertString:@"-" atIndex:9];
 self.ts.text = stringts;

Swift 4.2

Handles 10 and 11 digit phone numbers that may or may not already have formatting or non-digit characters in the string.

Will handle:

<li>1234567890, 12345678901, 123 456 7890, 123-456-7890, (123) 456-7890, 1-234-567-8901</li>
</ul>

Result: 

<ul>
<li>(999)-999-9999</li>
<li>1(999)-999-9999</li>
</ul>

Code:

<pre><code>extension String {

 /// Handles 10 or 11 digit phone numbers
 ///
 /// - Returns: formatted phone number or original value
 public func toPhoneNumber() -&gt; String {
 let digits = self.digitsOnly

 str.insert("(", at: 0)
 str.insert(")", at: 4)
 str.insert("-", at: 8)
 return str as String

to use 

<pre><code>let nsMutableString = NSMutableString(string: "3022513240")
let strModify = self.PhoneNumberFormate(str: nsMutableString)

In my app, I have a string like:

<blockquote>
 "3022513240"
</blockquote>

I want to convert this like:

<blockquote>
 (302)-251-3240
