Issue #1 - Turn Me Loose

Welcome to the first issue of the bi-weekly newsletter "Open Source Updates for Swift Projects". Learn about new projects and innovations of popular projects that help you as a Swift / iOS developer.

I'd love to receive your input and suggestions to include in this newsletter. Please share them with me via email.

Swift Structured Concurrency in Nuke 11

Swift Structured Concurrency was THE hot topic in last year's WWDC. It is not an easy undergoing to update projects. Happy to see that Nuke, a popular Image Loading System, embraces Swift Structured Concurrency with full feature parity with legacy completion-based APIs in its latest version 11.0

There are no major source-breaking changes in this release. Instead, it adds dozens of API refinements to make the framework more ergonomic.

Work with the App Store Connect API 2.0

Bagbutik 2.0 already supports many new endpoints of the App Store Connect API 2.0.

Soon the open-source SDK from Antoine v.d. SwiftLee will follow. If you want a preview, check out his 2.0 Beta version.

Generate man pages with Swift Argument Parser

ArgumentParser 1.1.3 includes a SwiftPM plugin for generating man  pages. It is suggested that you can explore the functionality and configuration by running swift package plugin experimental-generate-manual --help from your package root.

But hold your horses! Due to an accident, the plugin is only visible within ArgumentParser. A pending PR just waits to get merged to fix the issue.

ArgumentParser 1.1.3 includes a SwiftPM plugin for generating man pages. However, this plugin is not visible to packages that declare ArgumentParser as a package dependency. Defining a product of type plugin in the package manifest will solve that.

You might ask: "What is the advantage of man pages over the generated help option?" ⬇️

Code Formatting With Swift Package Plugins

With Swift 5.6 it is possible to write either command (or build tool) Swift Package plugins. Xcode 14 integrates command plugins and allows them to operate on Xcode projects. No wonder developers have started to implement plugins. A widespread use case is to format source code.

A few days earlier, I created a less opinionated plugin that uses and works on projects in Xcode 14.

How to find Swift Package Plugins?

You can search for plugins on Swift Package Index :)

With Swift 5.6, Xcode and the Swift Package Manager gained a new product type, plugins, and we’re delighted to announce we now have support for filtering search results by whether or not they include a plugin.

Tuist & XcodeGen supports new product types

Xcode 14 introduced a few new frameworks and associated extension product types:

The new extensions have a new product type

If you use tools like and to avoid messing with .xcodeproj files manually, then you are probably happy to hear that those new product types are supported in their latest releases.

Add .extensionKitExtension as the new PBXProductType

Added support for new target type extensionkit-extension in Xcode 14 #1228 @aleksproger


Another shameless plug: I created a lightweight, dependency-free Swift Package to backport the new URL APIs from iOS 16.
