The builder pattern allows you to create objects with varying configurations without the need to have multiple constructors with different parameter combinations.
Choose Codable for well-defined JSON structures, JSONSerialization for simple parsing tasks or legacy codebases, and SwiftyJSON for dynamic or exploratory parsing needs.
While KVO and KVC are related and both are part of Cocoa's observation mechanism, they serve different purposes and operate at different levels of abstraction.
In DI, dependencies are provided to it from an external source, typically through constructor injection, property injection, or method injection instead of a class creating itself.
Swift offers a few ways to handle multiple asynchronous tasks, depending on whether you need them to run concurrently or wait for their results.
In Swift, private provides the strictest level of access control. You should only use fileprivate when you have a specific reason to allow access from other parts of the same file.
Swift 5.10 accomplishes full data isolation in the concurrency language model. This important milestone has taken years of active development over many releases.
Method compactMap removes nil results from optional value sequences during transformation, and flatMap flattens nested sequences into a single level sequence.
Variadic parameters are useful when you want to create a function that can take any number of arguments of a specific type without specifying them individually.
Both computed properties and methods can provide dynamic behavior, allowing you to calculate values or perform actions based on the current state of an instance.
