Ifrit

Super lightweight lib for fuzzy searching.

Works on iOS / macOS / Linux / Android and more:

This repository is built upon the archived Fuse-Swift project by KRisk: https://github.com/krisk/fuse-swift

What is fuzzy Search?

A fuzzy search algorithm is designed to find approximate matches for a given search query.

Let's say you have a list of products, and a user is looking for a "Czy Swetr,". Exact match will return nothing, but the fuzzy search will find "Cozy Sweater.".

If you need exact match - you need to use standard function .filter { } instead of this library.

Difference: Ifrit VS Fuze-Swift?

- Fuze-Swift: Swift 5.1~
+ Ifrit: Swift 6.2 compatible
+ Fuze-Swift support Pods and Packages :)
Ifrit supports only Packages :(
Fuze-Swift is dead :(
+ 🔥🔥🔥 Ifrit is Fuse-Swift, reborn from the hells ashes! But more powerful and alive than ever! 🔥🔥🔥 :)
Fuse-Swift supports asynchronous functions with callbacks but lacks native async/await support. :(
+ Ifrit supports callbacks and async/await both :)
Fuze-Swift have async/multithreading issues. Crashes is possible :(
+ Ifrit is stable and crash-free!
Fuse-Swift's async functions return incorrect results - wrong indexes. :((((
+ Ifrit's async functions return correct indexes and are fully covered with tests :)
Fuze-Swift was written for Xcode 11 and now generates numerous warnings :(
+ Ifrit's code is updated to the latest Swift standards of 2026 year :) 
But Ifrit still have a few build warnings :(
+ Ifrit - extended coverage with automated tests :)
+ Ifrit features an additional search system using the Levenshtein distance algorithm. :)
+ Ifrit allows searching by multiple search templates
+ Ifrit's syntax has been slightly adjusted for improved flexibility
+ Ifrit's sync search is 2% faster than Fuse's (using M1 processor and standard settings).
+         Async search performance remains the same as Fuse's (standard settings).+ Ifrit was ported to Kotlin programming language: https://github.com/dfabulich/skip-ifrit
