Date Range picker in SwiftUI

Kyryl shows how to build a flexible date-range picker in SwiftUI that supports presets as week/month/year and also lets users pick a custom span.

Date Range picker in SwiftUI

When you work with various data and want to analyze or review it, you often face a problem: that certain periods of dates must be selected only. In mobile apps, this is a common functionality. Apple provided us with a great component, but, as usual, it’s not enough for many reasons.

Feature flags in Swift

Majid walks through how to use feature flags in Swift to conditionally enable or disable functionality depending on build configurations (Debug, TestFlight, App Store).

Feature flags in Swift

Almost every project I work on has at least three build configurations: Debug, TestFlight, and App Store. These configurations differ not only in build settings but also in functionality. This week, we’ll learn how to implement feature flags in Swift, which allow us to toggle on and off specific functionalities under certain conditions.

When should you use an actor?

Matt explores when actors are the right tool in Swift, explaining their unique isolation domain capabilities, why this protection mechanism matters for concurrent programming and outlining the specific conditions that make them the optimal choice.

When should you use an actor?

I enjoy technical conversations that happen across different blogs. One in particular that I revisited recently was a very thought-provoking exchange on enum vs struct. The whole thing is worth your time!

We all love how sturdy, precise and satisfying the MacBook hinge is, so you might wonder why anyone would want to make it sound like a creaky old door!
But here’s the fascinating part: there’s actually a sensor that tracks the exact angle of your screen hinge that developer Sam Henri Gold managed to use.

He then decided to turn the MacBook into a playable theremin!
It’s a perfect example of how a simple sensor can become unexpectedly entertaining when creative developers get their hands on it!
Just be careful not to break your MacBook!
