Performant, sleek and elegant.
The author discusses challenges managing side projects, specifically updating SignalPath to Swift 6. They encountered errors related to multiple notification observations but resolved them by shifting to publishers, avoiding sendable closure issues. Although the new approach risks background thread notifications, the compiler is satisfied with the adjustments made to the code.
AnyClass is a protocol all classes conform to and it comes with a feature I was not aware of. But first, how to I ended up with using AnyClass. While working on code using CoreData, I needed a way to enumerate all the CoreData entities and call a static function on them. If that function [ ]
Xcode 16 introduces a new execution engine for Previews, enhancing project configuration support and improving performance by up to 30%. However, it wraps SwiftUI views in AnyView for debug builds, which can hinder optimization. Users can override this behavior with a custom build setting to maintain performance in debugging.
Swift s foundation library provides a sorted(by:) function for sorting arrays. The areInIncreasingOrder closure needs to return true if the closure s arguments are increasing, false otherwise. How to use the closure for sorting by multiple criteria? Let s take a look at an example of sorting an array of Player structs. As said before, the closure should [ ]
DateFormatter is used for converting string representation of date and time to a Date type and visa-versa. Something to be aware of is that the conversion loses microseconds precision. This is extremely important if we use these Date values for sorting and therefore ending up with incorrect order. Let s consider an iOS app which uses [ ]
It is not often when we need to wrap an async function with a completion handler. Typically, the reverse is what happens. This need can happen in codebases where the public interface can t change just right now, but internally it is moving towards async-await functions. Let s jump in and see how to wrap an async [ ]
After a couple of years, I tend to get tired of looking at the same colour scheme in Xcode. Then I spend quite a bit of time looking for a new theme and then coming back with empty hands. Material default has served me for a while, but it never felt like a perfect colour [ ]
Observation framework came out along with iOS 17 in 2023. Using this framework, we can make objects observable very easily. Please refer to @Observable macro in SwiftUI for quick recap if needed. It also has a function withObservationTracking(_:onChange:) what can be used for cases where we would want to manually get a callback when a tracked [ ]
It took a long time, I mean years, but it finally happened. I stumbled on a struct which had a property of the same type. At first, it is kind of interesting that the replies property compiles fine, although it is a collection of the same type. I guess it is so because array s storage [ ]
In addition to scroll related view modifiers covered in the previous blog post, there is another one for detecting scroll view phases aka the state of the scrolling. The new view modifier is called onScrollPhaseChange(_:) and has three arguments in the change closure: old phase, new phase and a context. ScrollPhase is an enum with [ ]
