2FAS Auth for iOS
Source code for 2FAS Auth iOS app
2FAS Auth for iOS is the official iPhone and iPad client for the 2FAS authentication platform, offering users a secure and privacy-focused mobile app to manage multi-factor authentication (MFA) tokens for their online accounts. The app generates time-based one-time passwords (TOTP) and counter-based one-time passwords (HOTP) that are widely required for logging into services with enhanced security, and it lets users scan QR codes or manually enter secret keys to register new accounts. Designed with native iOS conventions, it supports Face ID and Touch ID to quickly unlock the app while keeping authentication secrets encrypted locally on the device, so sensitive data never leaves the user’s control. The client is also structured to work offline, meaning you can generate codes without a network connection, and it integrates with companion browser extensions or other 2FAS sync tools so tokens can be backed up or restored across devices securely. -

Attabench
Microbenchmarking app for Swift with nice log-log plots
Attabench is a microbenchmarking app for macOS, designed to measure and visualize the performance of Swift code. This app is for microbenchmarking low-level algorithms with one degree of freedom (usually size). It works by repeatedly performing the same operation on random data of various sizes, while continuously charting the results in nice plots. Attabench's default log-log plots are ideal for seeing your algorithm's performance at a glance. Attabench was originally created to supply nice log-log charts for my dotSwift 2017 talk and Optimizing Collections book. At the time, it seemed easier to build a custom chart renderer from scratch using Core Graphics than to mess with a bunch of CSV files and pivot tables in Excel. (It has to be noted though that this opinion has been somewhat weakened during the implementation process.) -

Bagel
A little native network debugging tool for iOS
Bagel is a little native iOS network debugger. It's not a proxy debugger so you don't have to mess around with certificates, proxy settings etc. As long as your iOS devices and your Mac are in the same network, you can view the network traffic of your apps separated by the devices or simulators. Most basic usage is to start Bagel iOS before any network operation. Since Bagel exposes every request info to the public it would be better if you disable it for the store versions. By default, Bagel gets your project name and device information. The desktop client uses this information to separate projects and devices. You can configure these if you wish. Bagel framework communicates with the desktop client by using Bonjour protocol. You can also configure these Netservice parameters. -

Cluster
Easy Map Annotation Clustering
Cluster is an easy map annotation clustering library. This repository uses an efficient method (QuadTree) to aggregate pins into a cluster. Create an object that conforms to the MKAnnotation protocol, or extend an existing one. Next, add the annotation object to an instance of ClusterManager with add(annotation:). Implement the map view’s mapView(_:viewFor:) delegate method to configure the annotation view. Return an instance of MKAnnotationView to display as a visual representation of the annotations. The ClusterAnnotationView class exposes a countLabel property. You can subclass ClusterAnnotationView to provide custom behavior as needed. Here's an example of subclassing the ClusterAnnotationView and customizing the layer borderColor. -

Connectivity
Makes Internet connectivity detection more robust by detecting Wi-FI
Connectivity is a wrapper for Apple's Reachability providing a reliable measure of whether Internet connectivity is available where Reachability alone can only indicate whether an interface is available that might allow a connection. Connectivity's objective is to solve the captive portal problem whereby an iOS device is connected to a WiFi network lacking Internet connectivity. Such situations are commonplace and may occur for example when connecting to a public WiFi network which requires the user to register before use. Connectivity can detect such situations enabling you to react accordingly. -

GIOVANNI
A Gameboy Emulator for the Apple Watch
Games are loaded from your iPhone's documents directory. In iTunes, drop .gb or .gbc files into the Giovanni app documents folder, and they'll show up automatically on your Apple Watch. When you play a game for the first time, it'll download to your watch and get cached in the watch's documents directory. Subsequent loads are immediate. Emulator saving and loading is automatic and happen whenever the app gets closed/inactivated or opened/activated. In-game saving and loading is completely separate. If for some reason the emulator save gets corrupted, force-touching the screen will bring up the option to reset the emulator, allowing you to resume your in-game save. -

Pulse
Logger and network inspector for Apple platforms
There is always this friction when it comes to debugging native apps: you can’t inspect anything that happens behind the scenes unless you use special tools, not even network requests. That’s not the case on the web with tools like Safari Web Inspector. I wanted to bring something similar to native apps. What is Pulse? It’s a persistent logger with a network inspector, but not just a tool. It’s also a framework. PulseCore.framework (iOS, macOS, watchOS, tvOS) provides a logger itself and a network proxy for automatically capturing network requests. PulseUI.framework (iOS, macOS, watchOS, tvOS) containing all the UI components you’ll see on the screenshots. Document-based Pulse apps (iOS, macOS) to view logs shared from other devices. As a developer, you integrate the frameworks into your app and configure them to capture logs and network traffic. You then add a way to display a Pulse console to view logs right on the device. -

Raivo OTP
A native, lightweight and secure one-time-password (OTP) client
Raivo OTP’s iOS application is a native, secure, and user-friendly two-factor authentication (2FA) client that generates time-based (TOTP) and counter-based (HOTP) one-time passwords to protect accounts, all built specifically for iOS devices using modern Swift. It helps users replace or supplement traditional SMS or email 2FA by securely storing OTP secrets and displaying rotating codes that can be synced via iCloud across Apple devices, reducing the risk of losing access when switching devices. Users can easily add new accounts by scanning QR codes or entering secrets manually, assign custom icons for better visual organization, and quickly search through stored tokens to find the one they need. The app includes optional biometric unlocking with Face ID or Touch ID so access to sensitive OTPs remains both fast and secure. It also supports encrypted backups and exports, letting users archive their data safely offline or transfer it between devices. -

Swift System
Low-level system calls and types for Swift
Swift System provides idiomatic Swift interfaces to low-level system calls and types, aiming to be the canonical home for these building blocks on all supported Swift platforms. It wraps platform details behind portable APIs while still allowing you to drop down to exact OS semantics when needed. The design follows Swift’s value semantics and protocol orientation to keep code predictable and testable. It’s distributed via SwiftPM with tagged releases, making it straightforward to pin versions in larger stacks. Over time, the library is intended to centralize foundational syscalls so other packages don’t reinvent thin wrappers. Escape hatches to exact platform behaviors when required. This consolidation improves consistency, documentation quality, and cross-platform behavior for systems programming in Swift. Portable, idiomatic wrappers for system calls and types. -
22
SwiftLog
A Logging API for Swift
swift-log is the official, vendor-neutral logging API for Swift, providing a small, performant core that libraries and applications adopt to avoid logger lock-in. It defines common logging semantics and levels, plus a lightweight façade that backends can implement—so the same application code can run with different logging engines (e.g., OSLog on Apple platforms or custom sinks on servers). The package embraces Swift Package Manager, offers a clean Logger API, and is widely used across the Swift on server and Apple-platform ecosystems. The repo’s release notes and ecosystem links show active maintenance, CI coverage for recent Swift versions, and community-supplied backends. By decoupling the API from any one implementation, swift-log simplifies composition: frameworks can log consistently without dictating the logging stack to end users. It’s a foundational building block for production Swift services, tools, and apps looking for consistent, structured telemetry. -

SwiftNIO
Network application framework for protocol servers and clients
SwiftNIO is a cross-platform asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Low-level protocol implementations are often a collection of ChannelHandlers that implement a protocol but still require the user to have a good understanding of SwiftNIO. Often, low-level protocol implementations will then be wrapped in high-level libraries with a nicer, more user-friendly API. High-level implementations are usually libraries that come with an API that doesn't expose SwiftNIO's ChannelPipeline and can therefore be used with very little (or no) SwiftNIO-specific knowledge. The implementations listed below do still do all of their I/O in SwiftNIO and integrate really well with the SwiftNIO ecosystem. SwiftNIO aims to support all of the platforms where Swift is supported. Currently, it is developed and tested on macOS and Linux. -
24
SwiftTreeSitter
Swift API for the tree-sitter incremental parsing system
Swift API for the tree-sitter incremental parsing system. The SwiftTreeSitter target is a close match to the C runtime API. It adds only a few additional types to help support querying. It is fairly low-level, and there will be significant work to use it in a real project. SwiftTreeSitterLayer is an abstraction built on top of SwiftTreeSitter. It supports documents with nested languages and transparent querying across those nestings. It also supports asynchronous language resolution. While still low-level, SwiftTreeSitterLayer is easier to work with while also supporting more features. -
