Announcing SwiftNIO IMAP

As part of expanding the Swift on Server ecosystem, we’re thrilled to announce the release of a new IMAPv4 parser and encoder, SwiftNIO IMAP. This package implements: Parsing IMAPv4 wire-format to type-safe Swift data structures Encoding these Swift data structures to the IMAPv4 wire format Extensive support for common IMAP extensions High performance Integration with SwiftNIO Motivation Email has been a indispensable part of the internet for over 40 years and is a ubiquitous part of many products and services today. Internet Message Access Protocol (IMAP) is the most widely used open standard to retrieve email messages. It has been…

Swift Extension For Visual Studio Code

As Swift is deployed across more platforms, it is important that Swift can be developed on more platforms as well. The Swift Extension for Visual Studio Code provides a cross-platform solution for Swift development supporting macOS, Linux, and Windows. Motivation Swift is held back from extending outside the Apple ecosystem by the lack of a first-class, integrated development environment on non-Apple platforms. There is no Xcode if you are developing on Linux or Windows. Until this point there have been individual components to make up that development environment like Apple’s SourceKit-LSP project and support for the Swift version of LLDB when using the CodeLLDB extension, but…

Swift Language Announcements From WWDC22

Swift has evolved significantly during the past year, and we’ve seen two large updates to the language. Swift 5.6 was released in March 2022 and introduced major improvements to the type system, concurrency model and Swift ecosystem. It laid the groundwork for further updates in Swift 5.7, which is included in beta versions of Xcode 14 and available on the Swift.org downloads page. Many Swift updates were rightfully celebrated during WWDC22, with sessions focusing on language changes, tooling improvements, additions to Swift packages and more. The What’s new in Swift video provides a great overview of Swift news for the past year. In this post we would like…

Exploring Swift: Property Wrappers In The Wild

Property wrappers were introduced in Swift 5.1 as a way to make it easier to reuse common programming patterns, but since then they have grown to work with local context, function and closure parameters, and more. We’re lucky enough to have lots of creators in our community creating apps with property wrappers then writing about their experiences, and we’d like to share a few of our favorites with you here. In her talk on property wrappers from dotSwift 2020, Erica Sadun teaches us why property wrappers help us specify behavior contracts at the point of declaration rather than the point of use. Erica has been one…

Apple Provides Developers With Even More Powerful Technologies To Push The App Experience Forward

Apple today unveiled new tools, technologies, and APIs designed to help developers create even richer experiences for their users. Widgets on the Lock Screen enable developers to surface key information from their apps in a new way, while other new APIs across Apple’s platforms help them build more unique features. WeatherKit gives developers the ability to integrate Apple Weather forecast data directly into their apps, and Xcode Cloud — Apple’s continuous integration and delivery service built into Xcode — is now available to every Apple Developer Program member to help them create higher-quality apps, faster. Metal 3 enables gaming…

Introducing Swift Async Algorithms

As part of Swift’s move toward safe, simple, and performant asynchronous programming, we are pleased to introduce a new package of algorithms for AsyncSequence. It is called Swift Async Algorithms and it is available now on GitHub. This package has three main goals: First-class integration with async/await Provide a home for time-based algorithms Be cross-platform and open source Motivation AsyncAlgorithms is a package for algorithms that work with values over time. That includes those primarily about time, like debounce and throttle, but also algorithms about order like combineLatest and merge. Operations that work with multiple inputs (like zip does on Sequence) can be surprisingly complex to implement, with subtle behaviors and many edge cases to consider. A shared…

Why is the Swift Language Gaining Popularity? Is it Tailored Swift?

What is the Swift Language? Swift is a powerful and intuitive programming language developed by Apple Inc for iOS iPadOS, macOS, tvOS, watchOS, and Linux application development. Swift combines decades of experience in building Apple platforms with the latest research in programming languages. Swift APIs are even easier to read and maintain because named parameters are expressed in a clean syntax. Better yet, you don’t need to type semi-colons. Swift is a general-purpose, functional, imperative, and block-structured language for iOS development. Swift adopts the best of C and Objective-C, without the constraints of C compatibility. Swift is an object-oriented language…

Introducing Swift Collections

I’m thrilled to announce Swift Collections, a new open-source package focused on extending the set of available Swift data structures. Like the Swift Algorithms and Swift Numerics packages before it, we’re releasing Swift Collections to help incubate new functionality for the Swift Standard Library. The Swift Standard Library currently implements the three most essential general-purpose data structures: Array, Set and Dictionary. These are the right tool for a wide variety of use cases, and they are particularly well-suited for use as currency types. But sometimes, in order to efficiently solve a problem or to maintain an invariant, Swift programmers would…

Celebrating Black History Month

Black History Month is a time to learn about, reflect on, and celebrate the impact and accomplishments of the Black community. In honor of Black History Month, we have curated a handful of outstanding contributions from the Black Swift community to acknowledge and celebrate their impact on the Swift ecosystem. Creating educational resources There are many Black developers in the Swift community creating educational resources to help people develop their Swift skills. Kyle Lee (aka Kilo Loco) has created a wealth of hands-on tutorials for Swift — including language fundamentals, UI programming, open source frameworks, and more — always…

Introducing SwiftNIO SSH

I am delighted to introduce a new open source project for the Swift Server ecosystem, SwiftNIO SSH. Distributed as a Swift package, SwiftNIO SSH is designed to enable Swift developers to interact with the SSH network protocol. What is SwiftNIO SSH? SwiftNIO SSH is a programmatic implementation of SSH: that is, it is a collection of APIs that allow programmers to implement SSH-speaking endpoints. Critically, this means it is more like libssh2 than openssh. SwiftNIO SSH does not ship production-ready SSH clients and servers, but instead provides the building blocks for building this kind of client and server. There are…
