In this article we'll implement Dijkstra's algorithm in swift and we'll implement a simple priority queue that we'll use in the algorithm.

This is Part One of a two-part article that looks at how optionals in Swift can help us better model real-world domains, solve common programming problems and write more robust and expressive code. This part looks at why Swift has optionals, basic optional…

Human readable time diffs on lines of output when running e.g. build commands like fastlane - GitHub - agens-no/swiff: Human readable time diffs on lines of output when running e.g. build commands ...

I wrote a <code>UIAlertController</code> extension that allows you to perform validation of the text the user has entered while the alert is on screen. It’s nothing earth-shattering, but what I like about it is that the behavior is entirely encapsulated in…

Our topic this week is Hashable and its new related type, Hasher. Together, they comprise the functionality underlying two of Swift’s most beloved collection classes: Dictionary and Set

Hash values in Swift: more than just XOR.

MVC – The Past. MVVM with RxSwift or ReactiveCocoa, MVP – The Present. Functional Architectures – The Future.

I took the time to figure out how to read and write from HealthKit so you don’t have to!

Everything is connected nowadays. In a world where we share links as often as we do today, your app cannot be out of the loop. Deep linking…

Trigger custom errors and warnings during compile time and warn for TODOs in your codebase. Using #line and #file points you to the right file and method.

Binary search trees are one of the most fundamental data structures in computer science. We'll go over the theory and implement the binary search trees.
