Language Swift Version License Platform Swift Package Manager compatible

SwiftySweetness is a list of extensions that provides extra functionality and syntactic sugar.

Version 2 Changes

As of version 2.0.0 all UIKit and AppKit extensions have been removed. They have been moved to HotCocoa. This was done as this framework is meant to be a pure swift framework that should work cross platform without need for the Objective-C runtime.


Int & Double

Power operator **:

let power = 2 ** 4 // 16

Or assign the result to one of the variable arguments:

var num = 3
num **= 3 // 27

isNegative Bool property indicating whether or not the given number is negative:

if num.isNegative {


hasValue property to quickly check if the optional is nil or not:

var myOptional: Int? = nil
myOptional.hasValue // false


Use subscripts to get character at a given index:

let str = "Hello world!"
str[2] // 'l'

Or pass a range to get a substring:

str[2..<7] // "llo w"
str[2...7] // "llo wo"

trimmed returns a trimmed version of the string without leading or trailing whitespaces and newlines.

let str = "      \n\nMy String\n\n    \n"
str.trimmed // "My String"

splitCamelCase() splits a camel cased string.

let str = "thisIsACamelCasedString"
str.splitCamelCase() // "this Is A Camel Cased String"

initials() returns the first letter of each word in the string.

let str = "Hello World"
str.initials() // "HW"

Encodable & Decodable

Swift 4 makes encoding and decoding JSON easy with the Encodable and Decodable protocols:

let json = JSONEncoder().encode(myStruct)
let decodedStruct = JSONDecoder().decode(MyStruct.self, from: json)

But SwiftySweetness makes this even easier:

let json = myStruct.encode(to: .json)
let decodedStruct = MyStruct.decode(from: json, ofType: .json)


The PropertyRepresentable allows any conforming type to generate an array containing all its properties.

struct Person: PropertyRepresentable {
    var name: String
    var age: Int

let person = Person(name: "John Doe", age: "20")
person.properties() // [(label: "name", value: "John Doe"), (label: "age", value: 20)]
person.propertyLabels() // ["name", "age"]
person.propertyValues() // ["John Doe", 20]
person.propertiesDictionary() // ["name": "John Doe", "age": 20]


SwiftySweetness offers multiple pipe operators. Piping is supported for all unary, binary, and ternary functions. |> is the standard pipe operator. It will pipe the input on the left to the function on the right.

func add(_ x: Int, _ y: Int) -> Int {
    return x + y

let num = 4
num |> (add, -10) |> abs // 6

The |>? operator takes an optional and either pipes it to the given function if it has a value or returns nil if the value is nil. Note that the value returned is an optional.

let optional1: Int? = 4
optional1 |>? (add, 6) // 10 NOTE: This is of type Int?

let optional2: Int? = nil
optional2 |>? (add, 6) // nil

The |>! operator force-unwraps an optional and then pipes it to the given function. This should only be used when you are certain the value is not nil!

let optional1: Int? = 4
optional1 |>! (add, 6) // 10 NOTE: This is of type Int since the value was unwrapped

let optional2: Int? = nil
optional2 |>! (add, 6) // fatal error: unexpectedly found nil while unwrapping an Optional value

And much more!
