Operator Overloads

You can add, substract, multiply, divide other type variables without casting them:

let intNumber : Int = 10
let doubleNumber : Double = 5.5
let sum = intNumber + doubleNumber // sum value will be 15.5 Double

You are able to concatenate two array into first:

var array1 = [1, 2, 3]
let array2 = [4, 5, 6]
array1 += array2 // array1 value will be [1, 2, 3, 4, 5, 6]

Int and Int64 Extensions

Convert int to ascii character:

97.toCharacter // value will be Character("A")

Convert int to String:

123.toString // value will be String("123")

Double Float and CGFloat Extensions

Convert Double to String:

let d = 123.456789
d.toString = "123.456789"
d.toString() = "123.45"
d.toString(4) = "123.4567" // where 4 is the number of characters after point

Bool Extensions

Convert bool to String and Int

true.toString = "true"
false.toString = "false"
true.toInt = 1
false.toInt = 0

Character Extensions

Convert Character to Int (by ascii table):

Character("A").toInt = 97

String Extensions

Convert String to bool, Int, Double, CGFloat, HTTP URL, File Path etc...

("TRUE" | "True" | "true" | "YES" | "Yes" | "yes" | "1").toBool = true
("FALSE" | "False" | "false" | "NO" | "No" | "no" | "0").toBool = false
"123".toInt = 123
"123".toDouble = Double(123)
"123".toCGFloat = CGFloat(123)
"http://example.com/".toHttpURL = NSURL(sting: "http://example.com/")
"/path/to/file".toFileURL = NSURL(fileURLWithPath: "/path/to/file")

Get the length of the String:

"123456789".length = 9

Trim whitespace characters from String:

"   1 2 3 4   ".condenseWhiteSpace() = "1 2 3 4"

Substring To, From, From to To, Range:

"0123456789".substringTo(5) = "01234"
"0123456789".substringFrom(5) = "56789"
"0123456789".substring(4, to: 7) = "456"

Get the range of substring:

"0123456789".range("456") = NSRange(4, 3)

Append path component:

"/folder/subfolder".stringByAppendingPathComponent("subfolder2/file") = "/folder/subfolder/subfolder2/file"

Replace Characters with NSRange and return Value:

"0123456789".stringByReplacingCharactersInRange(NSMakeRange(4, 3), withString: "000") = "0123000789"

Replace Characters with NSRange:

var string = "0123456789"
string.replaceCharactersInRange(NSMakeRange(4, 3), withString: "000") // string value will be "0123000789"

Validate with regex:

"#hashtag".validate("#.*") = true
"#hashtag".validate("#.*")

Find regex matches:

do
{
let array = try "name1 name2 name3".matches("[a-zA-Z]{4}[0-9]{1}") // array value will be ["name1", "name2", "name3"]
}
catch
{
// handle an error here
}

Find ranges for values:

do
{
let array = try "name1 name2 name3".ranges("name") // array value will be [NSMakeRange(0, 4), NSMakeRange(6, 4), NSMakeRange(12, 4)]
}
catch
{
// handle an error here
}

Get Characters and substrings via subscripts:

"123"[1] = Character("2") // Character value
