Imagine that you’re a developer in a large company working to solve a high-profile architectural problem in an app. Your team has compiled all of the company’s use-cases within that particular problem and developed a framework that solves not only all of those use-cases but also some additional ones that you’re expecting developers will need […]

SwiftUI’s various stacks are some of the framework’s most fundamental layout tools, and enable us to define groups of views that are aligned either horizontally, vertically, or stacked in terms of depth. When it comes to the horizontal and vertical variants (HStack and VStack), we might sometimes end up in a situation where we want […]
I had to leave my gaming computer behind when I moved to another country and have ever since felt an empty spot in my life. I watched many interesting games get released as the years went by, but I didn’t feel it was enough justification to buy a gigantic gaming desktop again as I don’t […]
I have been feeling that Reddit is well on its way to taking away from 4chan the title of internet hate machine, because even when a subreddit is themed around happiness it takes little to no effort to find extremely hostile comment chains with complete strangers arguing about the most pointless things. I was curious […]
117: “Swift 5.7, generics, and the road to Swift 6”, with special guest Ben Cohen | Swift by Sundell
Ben Cohen, manager of the Swift team at Apple, joins John on this WWDC22 special to discuss Swift 5.7, how generics have been made more powerful and easy to use, and how the language is expected to evolve towards Swift 6.

Combining Swift’s flexible generics system with protocol-oriented programming can often lead to some really powerful implementations, all while minimizing code duplication and enabling us to establish clearly defined levels of abstraction across our code bases. However, when writing that sort of code before Swift 5.7, it’s been very common to run into the following compiler […]
Swift 5.7 introduces a new, more concise way to unwrap optional values using if let and guard let statements. Before, we always had to explicitly name each unwrapped value, for example like this: class AnimationController { var animation: Animation? func update() { if let animation = animation { … } } } But now, we […]
