Swift AI
The Swift machine learning library
Swift AI is a high-performance deep learning library written entirely in Swift. We currently offer support for all Apple platforms, with Linux support coming soon. Swift AI includes a collection of common tools used for artificial intelligence and scientific applications. A flexible, fully-connected neural network with support for deep learning. Optimized specifically for Apple hardware, using advanced parallel processing techniques. We've created some example projects to demonstrate the usage of Swift AI. Each resides in their own repository and can be built with little or no configuration. Each module now contains its own documentation. We recommend that you read the docs carefully for detailed instructions on using the various components of Swift AI. The example projects are another great resource for seeing real-world usage of these tools. Swift AI currently depends on Apple's Accelerate framework for vector/matrix calculations and digital signal processing. -

SwiftChart
Line and area chart library for iOS
Line and area chart library for iOS. The chart can be initialized from the Interface Builder. Drag a normal View into a View Controller and assign to it the Chart Custom Class from the Identity Inspector. As you can see, as default the values on the x-axis are the progressive indexes of the passed array. You can customize those values by passing an array of (x: Double, y: Double) tuples to the series initializer. Use the chart.xLabels property to make the x-axis showing more labels than those inferred from the actual data. To make the chart respond to touch events, implement the ChartDelegate protocol in your class, e.g. a View Controller, and then set the chart’s delegate property. -

SwiftOCR
Fast and simple OCR library written in Swift
SwiftOCR is a fast and simple OCR library written in Swift. It uses a neural network for image recognition. As of now, SwiftOCR is optimized for recognizing short, one-line long alphanumeric codes (e.g. DI4C9CM). We currently support iOS and OS X. If you want to recognize normal text like a poem or a news article, go with Tesseract, but if you want to recognize short, alphanumeric codes (e.g. gift cards), I would advise you to choose SwiftOCR because that's where it exceeds. Tesseract is written in C++ and over 30 years old. To use it you first have to write a Objective-C++ wrapper for it. The main issue that's slowing down Tesseract is the way memory is managed. Too many memory allocations and releases slow it down. -

SwiftUI Drawer
A SwiftUI bottom-up controller, like in the Maps app
SwiftUI Drawer is a UI component that implements a draggable bottom sheet interface similar to those found in modern mobile apps like Apple Maps, enabling users to expand or collapse content panels interactively. It is built entirely using SwiftUI, leveraging declarative patterns to define layout behavior and interactions in a concise and flexible way. The component allows developers to specify multiple resting heights, giving the drawer different states that users can snap to when dragging. It integrates seamlessly into existing layouts using a ZStack structure, where the drawer sits above other content and responds to gestures naturally. The library includes support for animations and haptic feedback, enhancing the tactile feel of interactions and improving user experience. It also provides customization options such as alignment, width, and responsive layout adjustments depending on device orientation or screen size. -

TKSubmitTransition
Animated UIButton of Loading Animation and Transition Animation
Animated UIButton of loading animation and transition animation. As you can see in the GIF animation demo, you can find the “sign in” button rolling and after that, the next UIViewController will fade in. -

Time
Type-safe time calculations in Swift
Type-safe time calculations in Swift. Time is not just a bunch of Double conversion functions. The main advantage of it is that all time units are strongly-typed. Starting with Xcode 11, Time is officially available only via Swift Package Manager. Of course, you always have an option of just copying-and-pasting the code - Time is just two files, so feel free. -

Tokamak
Framework for building browser apps with WebAssembly
Tokamak is an open source framework that aims to replicate a large portion of Apple’s SwiftUI API in order to enable developers to build user interfaces that can run in the browser through WebAssembly as well as on native platforms. It provides a declarative programming model similar to SwiftUI, allowing developers to define views, state, and layout logic using familiar patterns while targeting environments beyond Apple’s ecosystem. The project includes a DOM renderer capable of handling a subset of SwiftUI views and modifiers, alongside additional constructs such as custom HTML rendering for greater flexibility when interacting with web technologies. Tokamak also introduces features like dynamic HTML elements with event listeners and direct DOM manipulation capabilities, which bridge the gap between Swift abstractions and browser-level control. Its architecture draws inspiration from modern UI frameworks. -

TweenKit
Animation library for iOS in Swift
TweenKit is a powerful animation library that allows you to animate (or 'tween') anything. TweenKit's animations are also scrubbable, perfect for building awesome onboarding experiences! By adding conformance to the Tweenable protocol, anything can be animated. You decide what it means to 'tween' your object, making this a flexible approach. -

XCoordinator
Powerful navigation library for iOS based on the coordinator pattern
Powerful navigation library for iOS based on the coordinator pattern. Create an enum with all of the navigation paths for a particular flow, i.e. a group of closely connected scenes. (It is up to you when to create a Route/Coordinator. As our rule of thumb, create a new Route/Coordinator whenever a new root view controller, e.g. a new navigation controller or a tab bar controller, is needed.). Whereas the Route describes which routes can be triggered in a flow, the Coordinator is responsible for the preparation of transitions based on routes being triggered. We could, therefore, prepare multiple coordinators for the same route, which differ in which transitions are executed for each route. -

XcodeProj
Read, update and write your Xcode projects
XcodeProj is a library written in Swift for parsing and working with Xcode projects. It's heavily inspired by CocoaPods XcodeProj and xcode. Using swift-sh you can automate project-tasks using scripts, for example, we can make a script that keeps a project’s version key in sync with the current git tag that represents the project’s version. Future adaption could easily include determining the version and bumping it automatically. If so, we recommend using a library that provides a Version object. Want to start using XcodeProj? Start by digging into our documentation which will help you get familiar with the API and get to know more about the Xcode projects structure. -

iOS Interview Questions
iOS interview questions
This repository collects a broad, categorized list of interview questions (with expected answers) that are commonly asked in iOS or Swift engineering interviews. Topics range from language fundamentals (memory management, ARC, value vs. reference types), to UIKit/SwiftUI, concurrency, Grand Central Dispatch, background execution, networking, design patterns, system frameworks, and architecture decisions. Each question is usually backed by sample explanations or code snippets, helping candidates understand not just what to answer but why it matters and how to reason about tradeoffs. Because the repo is maintained, it evolves to reflect changes in the iOS ecosystem: for example, newer Swift concurrency, Combine, SwiftUI, structured concurrency, or recent platform APIs. Many interviewers and candidates use it as a structured prep tool: reviewing categories, doing mock answers, or drilling tricky concepts.
