A+ programming moments

Xcode 26.4 brought nice new usage possibility in the Package manifest.

Say I have ParentDataSource which holds a strong reference to ChildDataSource, which has a callback method that ParentDataSource implements: final class ChildDataSource: NSObject { var dataRefreshed: () -> Void = {} } final class ParentDataSource: NSObj…

If you go with the solution 1 to the previously discussed issue, I strongly suggest you embed variable fonts inside your app.

Today I encountered frustrating issue while working on custom font styling in an iOS app.

Building a complex iOS project with the Release scheme would hang indefinitely - no errors, no messages, just stuck.

Ever since ChatGPT and its gen-AI ilk arrived, I have been very vocal and adamant that these are bullshit generators: they try to guess what you want and will continually hallucinate things until you say it’s OK.

After upgrading all my active projects to Swift 6 language mode, I was bound to encounter some head-scratching edge cases.

Apple has great API for this purpose: URLSessionUploadTask.

I don’t think I wrote many apps in the last 10 years that did not involve Core Data.

Swift Package Manager dependency resolution mostly work logically: ① First you specify the dependency in any number of ways, here’s the most usual one: dependencies: [ .package( url: "https://github.com/radianttap/Alley", from: "3.0.0" ), ② Then you

While I knew about and even tried various very early attempts to run macOS on non-Apple hardware, it wasn’t until early 2020 that I’ve built my first proper one.

Let’s say you are writing an iOS client for Spotify’s API, specifically the search endpoint.

Imagine a simple sports app model: League entity, with some id, name and displayOrder properties.

When designing Core Data object graph, I spend copious amount of time thinking through each entity’s attributes and relationships.

UILabel has ability to render rather complex text through .attributtedText but is not user-interactive by default.

Last several weeks, we (Radiant Tap) are working on a major app redesign for one of our clients.

OptionSet is great tool of the Swift language.

Leonardo Maia Pugliese recently published a blog post that picked my interest: Coordinators and Tab Bars: A Love Story.

Two years ago I lamented the gaping hole in the Apple’s desktop Mac lineup.

I wrote about my Essentials snippers 4 years ago.
