README
__.swift
Now, _.swift is version 0.2.0! With the chain of methods, _.swift became more flexible and extensible.
Documentation: http://lotz84.github.io/__.swift/v0.1/ (Updates coming soon..)
_.swift aims to be an utility belt for a new programming language by Apple Inc., Swift. And we decided _.swift to be a clone of Underscore.js, which is an utility belt for JavaScript.
__.swift is a type-safe library because it uses type inference and generics. Therefore, you can write a program without most of the downcasting such as "as" or "as?".
Philosophy
- Type safe
- Flexible and Extensible
- Do not reinvent the wheel
- A port of Underscore.js to Swift
Installation
If you use __
from swift file, copy __.swift
folder into your project. That's all.
Examples
__.map([11,22,33]) { x in x * x }
// [121, 484, 1089]
__.reduce(["H", "e", "l", "l", "o", " ", "S", "w", "i", "f", "t", " ", "!", "!"], "", + )
// Hello Swift !!
func isPrime(n: Int) -> Bool {
if n < 2 { return false }
let max = Int(sqrt(Double(n)))
for i in 2...max {
if n % i == 0 { return false }
}
return true
}
__.find([1,33,173,46], isPrime)
// 173
__.filter(Array(2..100) , isPrime)
// [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]
let data = [
["plan": "walking", "time": "8 a.m."],
["plan": "work", "time": "10 a.m."],
["plan": "lunch", "time": "12 a.m."]
]
__.pluck(data, "plan")
// [walking, work, lunch]
let data2: Array<Dictionary<String, String>> = [
["species": "spider", "legs": "8"],
["species": "ant", "legs": "6"],
["species": "cat", "legs": "4"]
]
// Chain Example
__.chain(data).pluck("legs")?.map({(s:String) -> Int in s.toInt()! })?.sortBy(__.identity)?.value()
// [4, 6, 8]
