accessibilityInputLabels() lets Voice Control users activate UI controls with custom spoken commands. Without it, they'd have to recite the entire text of a view just to tap a button - imagine doing that when a stock price changes every second. www.hackingwithswift.com/articles/261...

I screwed up one key accessibility behavior, and now I'm on a mission to do better

Accessibility labels, hints, and grouping are great, but don’t forget to think about Voice Control too.

For HWS+ subscribers: StaticString is a string type that can only be created at compile time, which means no string interpolation and no surprises. It's perfect for cleaning up failable initializers when you know the value is always correct. www.hackingwithswift.com/plus/inside-...

StaticString – Hacking with Swift+

Sometimes less is more, and Swift's StaticString is a great example of how adding restrictions actually adds usefulness.

One-to-many is the most common SwiftData relationship type - one array on one side, an optional on the other. I'd still recommend making the inverse explicit though. www.hackingwithswift.com/quick-start/...

Dictionaries with non-String, non-Int keys couldn't encode cleanly into keyed containers. The new CodingKeyRepresentable protocol bridges that gap, letting custom key types participate in Codable properly. www.hackingwithswift.com/swift/5.6/co...

For HWS+ subscribers: Swift Argument Parser makes it easy to build useful macOS command-line tools, and a JSON tidier is a great first project. This one can prettify, compress, sort keys, and write output to a file, all in surprisingly little code. www.hackingwithswift.com/plus/command...

JSON Tidy – Hacking with Swift+

JSON is one of the most common file formats we deal with, so we can write a little macOS utility to make it nicer to work with – compressing the data, formatting the data, and even sorting the key nam...

Use @Attribute(.externalStorage) to hint to SwiftData that large data like images should live outside the main store. It handles everything transparently, just don't try using those properties in predicates. www.hackingwithswift.com/quick-start/...

Wow, I totally missed that over 400 apps are now using Kickstart Exchange! 🤯 It's a completely free advertising network for indie app developers, making it an incredibly effective way to find new users. exchange.kickstart.tools

Kickstart Exchange: free advertising for indie app developers

Your app shows ads for other indie apps, and every two shown earn one view of yours. Free, with no user tracking.

SwiftUI's Text view can format arrays, measurements, and currencies directly using the format parameter - no custom formatter needed. www.hackingwithswift.com/quick-start/...

What if you could build websites the same way you build SwiftUI apps, declaratively in pure Swift with no HTML required? That's the idea behind Ignite, and it works surprisingly well. 🔥 www.hackingwithswift.com/articles/266...

For HWS+ subscribers: Downloading data gets all the attention, but uploading Codable data cleanly is just as important. This walks through wrapping URLSession uploads with generics and Result for a much nicer API. www.hackingwithswift.com/plus/network...

Uploading Codable data – Hacking with Swift+

In a previous article we already looked at a great way to download data using Combine, but in this article we’re going to examine the other side of the problem: uploading Codable data. Apple’s API her...

I'm pleased to announce a new service for indie developers: Kickstart Signal, a feature request service you can embed in your app to track user requests, votes, comments, and more. Completely free, works on every Apple platform, and available today ✨ signal.kickstart.tools

Mark a SwiftData property with @Transient and it stays in memory only, never written to disk. Two rules: it needs a default value, and you can't use it in predicates. 💾 www.hackingwithswift.com/quick-start/...

Everything is in place for a nice new launch tomorrow 😎

Combining opaque types with primary associated types, you can write any Sequence<String> to express "any sequence of strings" - a constrained existential. The generics story in Swift keeps getting better. www.hackingwithswift.com/swift/5.7/co...

Somewhere out there is the GOAT who designed the classic iOS 6 Passbook shredding animation. I hope they are having a great day. ✨

safeAreaInset() lets you place content outside the safe area while automatically adjusting other views so nothing gets hidden. It works beautifully with ScrollView, List, and Form. www.hackingwithswift.com/quick-start/...

Every polished demo you've ever watched was built multiple times behind the scenes. Making mistakes isn't a sign you're failing - it's how learning actually works. www.hackingwithswift.com/articles/271...

Codable structs and enums work as SwiftData properties, but collections like [String] get stored as binary data and can't be used in predicates. Tread *carefully*. www.hackingwithswift.com/quick-start/...

Long, complex type annotations got a bit more manageable. Write _ for the parts you want Swift to infer, and spell out only what matters. A small addition, but surprisingly handy when working with deeply nested generic types. 🧩 www.hackingwithswift.com/swift/5.6/ty...
