Post published:June 21, 2022 Post category:Swift Post author:Lee Kah Seng The some and any keywords are not new in Swift. The some keyword was introduced in Swift 5.1 whereas the any keyword was introduced in Swift 5.6. In Swift 5.7, Apple makes another great improvement on both of these keywords. We can now use both of these keywords in the function’s parameter position! func doSomething(with a:
Some keyword in Swift: Opaque types explained with code examples
The some keyword in Swift declares opaque types, and Swift 5.1 introduced it with support for opaque result types. Many engineers experience working with opaque types for the first time when writing a body of a SwiftUI view. Though, it’s often unclear what some keyword does and when to use them in other places. With the introduction of Opaque Parameter Declarations in SE-0341, there are many more
Unit testing Combine-based Swift code | Swift by Sundell
Articles, podcasts and news about Swift development, by John Sundell. Testing asynchronous code is often particularly tricky, and code written using Apple’s Combine framework is no exception. Since each XCTest-based unit test executes in a purely synchronous fashion, we have to find ways to tell the test runner to await the output of the various asynchronous calls that we’re looking to test — othe
Phantom types in Swift
Phantom types in Swift 18 Feb 2021 Not every language with a static type system has so strong type-safety like Swift. Swift features like phantom types, generic type extensions, enums with associated types create an excellent foundation. This week we will learn how to use phantom types to build type-safe APIs. Enhancing the Xcode Simulators. Compare designs, show rulers, add a grid, quick actions
Swift(5.3) の Generic を学ぼう - iOSエンジニアのつぶやき
今回は、Swift における Generic Programming について理解を含めようということで、Swift の公式ドキュメントを眺めがらメモした内容をまとめていきます。 docs.swift.org 目次 Why generics? Generic Functions Type Parameters Generic Type Type Constraints Associated Types Generic Where Generic Subscripts Why Generics？ Generic Code を使用すると、定義した用件に応じて、任意の型で機能する柔軟で再利用可能な関数と型を記述できます。そのため、重複を避け、その意図を明確で抽象化された方法で表現するコードを書くことができます。 タイプセーフ コードの重複 ライブラリの柔軟性 Generics は Swift の
