SF Symbols ship with thousands of icons, and most apps use them as plain tinted images. That leaves a lot on the table. Each symbol is built from layers, comes in several shapes and weights, can show a value, and can move. This article …

Sooner or later one object needs to tell others that something happened. A music player starts a new track, a download finishes, the network drops. Swift gives us many ways to send that message, and picking the right one depends mostly on …

Besides coming up with a good idea and building the app, there are many other things you can do to boost your app’s visibility. I first wrote these notes as a Twitter thread in April 2021, based on Apple’s promote your app …

Apple’s App Review Guidelines are long and hard to read. This article covers the parts that matter most, in plain words.
When you break a rule, one of three things happens:

An AI agent is really just a loop. Your code sends a conversation to a language model, the model asks to run a tool, your code runs it and sends the result back, and this repeats until the model has enough to answer. The code around that …
Issue #1067
SwiftNIO is Apple’s networking framework for building servers and clients that move a lot of data without blocking threads. It powers Vapor, the AWS SDK for Swift, and gRPC Swift, and you can also reach for it directly when you need …
Issue #1066
The Model Context Protocol gives an AI assistant a standard way to discover and call tools outside the model itself. If you already have Swift code worth exposing, the official swift-sdk handles the JSON-RPC framing and the handshake for …
Issue #1065
Swipe actions used to require List. Even when a ScrollView and LazyVStack were the better fit for layout and performance, a swipeable row meant falling back to List just to get that one interaction.
SwiftUI now lets you attach …
Issue #1064
SwiftUI now ships a built-in way to let people drag items around in a list, stack, or grid, without writing gesture code or tracking drag offsets by hand.
Reordering splits into two responsibilities. The ForEach …
Issue #1063
Adding AI to an app used to mean calling a cloud API and accepting the latency, cost, and privacy trade-offs that come with it. The Foundation Models framework, introduced in iOS 26, removes that trade-off by giving you direct Swift …
Issue #1062
iPhone Duo is Apple’s first multi-display iPhone: a wide inner display split by a hinge, an outer display with its own aspect ratio, and support for split view multitasking and multiple scenes like iPad. If your app assumes a single …
Issue #1061
Starting with iOS 26, scroll views automatically blur their content where it slides behind a toolbar, tab bar, or any other pinned control. This is the scroll edge effect, and it’s part of the new Liquid Glass design language. Apple …
Issue #1060
Imagine a single IAM role that lives outside your stack, created once and reused by many deployments. Maybe it belongs to a partner service, a shared gateway, or a piece of platform infrastructure that several teams call into. Your CDK …
Issue #1059
Amazon Bedrock AgentCore Gateway turns existing APIs into MCP tools. Its built-in API Gateway target only works with public, REGIONAL or EDGE API Gateways, because it relies on API Gateway’s export-to-OpenAPI capability, which does …
Issue #1058
When you set endpointConfiguration.types to PRIVATE on a REST API, API Gateway still hands you a default URL, something like https://q6t71pmdq7.execute-api.eu-north-1.amazonaws.com/prod. That URL just will not resolve anywhere outside …
Issue #1057
Markdown is everywhere. Documentation, chat messages, AI responses, README files, most text-heavy apps eventually need to render it. SwiftUI has no built-in markdown view, so you have to build one. This article walks through the tools …
Issue #1056
Most HTTP requests are short-lived: send a request, wait for a complete response, close the connection. Server-Sent Events (SSE) breaks that pattern. The server sends a continuous stream of data over a single persistent connection, …
Issue #1055
Most HTTP requests follow a simple pattern: send a request, wait for a response, close the connection. WebSocket breaks that pattern. The connection stays open after the handshake, and both sides can push messages at any time without …
Issue #1054
Open almost any Kotlin project and you find two files: settings.gradle.kts and build.gradle.kts. It is rarely obvious which one does what. To clear that up, we will build a tiny Kotlin app, add an external dependency on http4k, then split …
Issue #1053
Plenty of Mac apps still run on an NSApplicationDelegate. The lifecycle works, the windows are wired up, and rewriting everything into the SwiftUI App protocol just to gain one settings window is hard to justify. The friction shows up the …
