Swift Concurrency is the most powerful paradigm in the language. Consequently, it’s also really bloody hard to learn. Not only are there dozens of keywords and APIs to learn; there are also some weird behaviours that can throw you off big-time. These unintuitive behaviours introduce footguns and WTFs-per-minute which act like Lego on the carpet of your barefoot learning journey. There are logical design decisions behind the unintuitive behaviour. Understanding these decisions builds up your own mental model. Your mental model codifies the obscure and brings enlightenment: an intuition for the unintuitive. Today we'll be going over: * Actor context inheritance in Tasks (and how it works under the hood) * Task hierarchy & the cascading cancellation misconception * Actor re-entrancy & interleaving, plus a very controversial question * Swift 6.2 Approachable Concurrency™ turning everything on its head again If you really want to cement your understanding of the gotchas, the best thing you can do is play with some code, add breakpoints, and inspect the thread debugger to see what’s physically happening. Fortunately for you, I also added a comprehensive open-source demo project to demonstrates each of these gotchas. I wrote about the most context inheritance, cascading cancellation, interleaving, and Swift 6.2 in Swift Concurrency's Biggest Unintuitive Gotchas 👽 blog.jacobstechtavern.com/p/swift-concur…

SwiftUI Agent Skill 3.0.0 just released! It can now parse xctrace data from Time Profiler, hangs, animation hitches, and SwiftUI traces, correlate issues with main-thread samples, and turn the whole firehose into JSON + Markdown an agent can actually reason about. Huge credit to @polpielladev for shipping the parser 🙌 Ready to make your SwiftUI app faster?

`withTaskGroup` and `withThrowingTaskGroup` are probably the most powerful tools in Swift Concurrency, unlocking massive parallelism in your code. Task Groups allow us to spin off any number of async functions in parallel and collect the results together, provided they return the same type.

Add -com.apple.CoreData.SQLDebug 1 as a launch argument and you can watch exactly what SwiftData is doing under the hood. Tip: don't delete it when you're done, just uncheck the box so it's ready when you need it again 🔍 hackingwithswift.com/quick-start/sw…

Many folks avoid actors due to a proliferation of “awaits” that can introduce subtle race conditions as multiple threads can interleave and access the actor’s data. But did you know you can squash many “awaits” down to a single one, eliminating race conditions in the process?

Tasks in Swift Concurrency are very similar to NSThreads! Both help manage processes, but live at different levels of abstraction. NSThread is an operating-system-level entity managed by the kernel. Each thread is a 512kB behemoth with its own call stack, making it expensive to context-switch between threads. The OS has to pause a thread, store its call stack somewhere safe, and resume it later. This overhead adds up in concurrent applications. Tasks are Swift Concurrency’s lightweight “unit of execution”. They are managed by the Swift Runtime and are scheduled on the Cooperative Thread Pool, which itself aims to maintain 1 thread per core. Asynchronous work on tasks store context in continuations, a.k.a. async frames, and they are designed to yield execution to avoid deadlock and blocking.

🚨 BREAKING Spanish Prime Minister Pedro Sánchez has officially announced the recognition of the State of Palestine, with East Jerusalem as its capital.

Whenever you consider creating a scrollable screen in SwiftUI, you think of using a List. It’s not always the best choice. Lists are great for displaying uniform data. For anything else, a ScrollView with a lazy stack is almost always the best option. swiftwithmajid.com/2026/04/06/bui…

SwiftUI provides several mechanisms for passing data between views. If it seems complicated to decide which data flow mechanism fits your particular situation, that’s because such decisions cannot be made in isolation. However, when you keep an app’s architecture in mind, it becomes easier to make the correct choice. Read how here: matteomanferdini.com/swiftui-data-f…
