How Swift Achieved Dynamic Linking Where Rust Couldn't - Faultlore
How Swift Achieved Dynamic Linking Where Rust Couldn't For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5. The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language without much compromise. So

This page describes the overall organization of documentation for the Swift toolchain. It is divided into the following sections: Tutorials gently guide you towards achieving introductory tasks, while assuming minimal background knowledge. How-To Guides help you complete specific tasks in a step-by-step fashion. Explanations discuss key subsystems and concepts, at a high level. They also provide b

How Do I Declare a Closure in Swift?
As a parameter to another function:funcName(parameter: (ParameterTypes) -> ReturnType) Note: if the passed-in closure is going to outlive the scope of the method, e.g. if you are saving it to a property, it needs to be annotated with @escaping. As a function parameter:array.sorted(by: { (item1: Int, item2: Int) -> Bool in return item1 < item2 }) As a function parameter with implied types:array.sor
Swift is a lot like Scala
A new programming language called Swift was announced at WWDC'14. Here's a source-to-source comparison of Swift and Scala using the examples given in "The Swift Programming Language" book published by Apple in the iTunes Store. I suspect the two are related ;-) Syntacticly, it's fair to say that Swift is a dialect of Scala. Swift inherits from Scala most of the "banner" features listed by Apple: T

5 Reasons Why Rubyist Will Love Swift | Littlelines
At Littlelines, we are very excited by Apple’s announcment last week of their brand new programming language for building iOS and Mac apps called Swift. As developers, we get very curious when new languages are announced and this was no exception. For the past week, I’ve been buried in books, articles, and screencasts on all things Swift. Along the way, I’ve recognized a few things about Swift tha

Is there a reason that Swift array assignment is inconsistent (neither a reference nor a deep copy)?
I'm reading the documentation and I am constantly shaking my head at some of the design decisions of the language. But the thing that really got me puzzled is how arrays are handled. I rushed to the playground and tried these out. You can try them too. So the first example: var a = [1, 2, 3] var b = a a[1] = 42 a b Here a and b are both [1, 42, 3], which I can accept. Arrays are referenced - OK! N

Typeclass encoding in Swift
In Swift, if we want to sum the elements of an array, we might write a function like this: func sumVecInt(xs: Array<Int>) -> Int { return xs.reduce(0) { $0 + $1 } } This works fine for Int, but what about when we want to sum an Array of Int8, Int32, or other number types? The + operator can only work on a fixed type, so using any other type will give us a type error. We would be forced to re-defin
