Visitor | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 31, 2023 The Visitor pattern is a pattern that allows developers to separate the algorithm from the object structure on which it operates. It allows developers to define a new operation without changing the classes of the objects on which it operates. The Visitor pattern involves two main components: the Vis
State | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 31, 2023 The behavioural design pattern for state, also known as the state pattern, is used to encapsulate an object’s behaviour based on its state. This pattern involves creating separate classes for each possible state of an object and delegating state transitions to these classes. The state classes are re
Strategy | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 31, 2023 The behavioural design pattern for strategy is used to encapsulate a family of algorithms or strategies and make them interchangeable. This pattern involves creating a set of classes that implement a common interface for performing a specific task. The context class, which uses the strategy classes,
Mediator | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 31, 2023 Behavioral design patterns are a set of design patterns that focus on improving the communication and interaction between objects in a software system. One such pattern is the Mediator pattern, which promotes loose coupling between objects by ensuring that they do not communicate directly with each
Memento | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 31, 2023 Behavioral design patterns are an essential aspect of software design that provide solutions to problems that arise in software development. One such pattern is the Memento pattern, which is used to capture and store an object’s state for later retrieval. The Memento pattern falls under the category
Chain of Responsibilities | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 23, 2023 Behavioral design patterns are essential for streamlining communication between objects in a software system. One such pattern, the Chain of Responsibilities, is particularly useful in organizing and managing how a request is handled by different components in a system. By decoupling the sender of t
Command | Swiftly Engineered iOS
Empowering Your iOS Development Journey, One Line of Code at a Time. Last updated on March 24, 2023 Behavioral design patterns are a set of design patterns that focus on the communication and interaction between objects. The Command pattern is one of the most commonly used behavioral patterns in software development. The Command pattern is a design pattern that encapsulates a request or command as
AttributedString in iOS 15 | Sarunw
AppLayouts: Extensive collection of resources to help you design and build your app for iOS and macOS in no time at all. Try for Free Introduction of AttributedString Over the years, Apple has made many improvements over old data types. We got an equivalent structural data type of reference types, e.g., String (NSString), Date (NSDate), Calendar (NSCalendar). In iOS 15, we got the new AttributedSt
Swift の「async let ...」と「TaskGroup」の使い分け早見表
/// `TaskGroup` を使って実装された `race(lhs:rhs:)` /// 本文中に実装を掲載しています let result = await race( lhs: { try? await Task.sleep(for: .seconds(100)) return 100 }, rhs: { try? await Task.sleep(for: .seconds(1)) return 1 } ) print(result) // 1 /// 同期的に `Int` が返ります（処理に0秒かかるとする、同期関数） func num0() -> Int { return 0 } /// 非同期的に `Int` が返ります（処理に1秒かかるとする、非同期関数） func num1() async -> Int { try! await Task.sleep(for: .seco
Swift 5.5から登場したActorについて
サンプルコード https://github.com/SatoTakeshiX/first-step-swift-concurrency/tree/main/try-concurrency.playground 対応するサンプルコードにはページ名を記載します。 検証環境 Xcode 13.2.1 Swift 5.5 データ競合 マルチスレッドプログラミングにおいて、重要な問題はデータ競合（data race)をいかに防ぐかです。複数のスレッドから一つのデータにアクセスした場合、あるスレッドがデータを更新するとデータが不整合を起こしてしまう可能性があります。デバックが非常に難しくやっかいなバグをになることが多いです。 データ競合がどういうものかをコードで解説します。 例えばゲームの点数を管理するScoreという型をクラスで定義します。 // Page: 3-1-data-race class
