Secure, URL-friendly, flexible and unique string ID generator for Swift. Swift realization of Nano ID. This specific project is a rework of the original project by @antiflasher in order to be compatible with SwiftPM and usable in server contexts. All credit for the original work goes to @antiflasher.
Installation
Add the following to your Package.swift dependencies, along with the appropriate name in your project’s target:
// Nano ID with default alphabet (0-9a-zA-Z_~) and length (21 chars)
let id = NanoID.new() // -> dtY0D_lLeJJjM~pogpcY9
// Nano ID with default alphabet and given length
let id = NanoID.new(12) // -> _xw7Sou69dSQ
// Nano ID with given alphabet and length
let id = NanoID.new(alphabet: .uppercasedLatinLetters, size: 15) // -> BFIXOAMLMKVSTYS
// Nano ID with preset custom parameters
let nanoID = NanoID(alphabet: .lowercasedLatinLetters,.numbers, size:10)
let idFirst = nanoID.new() // -> b08eochgzf
let idSecond = nanoID.new() // -> 80q1uxyf2p
Performance
Generation of 100,000 IDs of 0-9a-zA-Z_~ alphabet with length of 21 characters was tested.
On iPhone 5, iOS 10.3.3
Total time: 23.474965 secs (0.00023 sec per one ID)
On iPhone X, iOS 11.4
Total time: 1.631867 secs (0.00002 sec per one ID)
Variety
Among all 100,000 generated IDs the least used character occered 30,795 times. The most used character occured 31,650 times (2.7% bias)
