Mirror is quite simple. You create a Mirror to reflect any instance you want to inspect. Consider the following code: struct User { let name: String let age: Int } let michael = User(name: "Michael Scott", age: 44) // Create the mirror let mirror = Mirror(reflecting: michael) Once you have the mirror object…

…read-only data segment of the binary. These are initialized once at runtime in a thread-safe way and embedded into the binary alongside string literals and global constants. On the other hand, static var is stored in a global data section that supports write operations. Each static…

…original method with that of the new method, effectively redirecting the dispatch. extension UIViewController { @objc func track_viewDidLoad() { print("View Did Load: \(String(describing: type(of: self)))") self.track_viewDidLoad() } static func swizzleViewDidLoad() { let originalSelector = #selector(viewDidLoad) let swizzledSelector = #selector(track_viewDidLoad) guard let originalMethod = class_getInstanceMethod(self, originalSelector), let swizzledMethod…

…components: a path, an HTTP method, an optional request body, and a specific response type you expect to receive. Something like: enum HTTPMethod: String { case post case get } protocol APIRequest { associatedtype RequestBody: Encodable associatedtype Response: Decodable var path: String { get } var method: HTTPMethod { get } } Here, the RequestBody represents the encodable…

…created with a higher priority while the parent awaits their result. Consider the following example of an implicit child: struct UserProfile { var name: String var handle: String } struct ActivityItem { var description: String } func fetchProfile() async throws -> UserProfile { print("Child 1 (Profile): Fetching...") try await Task.sleep(for: .seconds(1)) // Simulate…

…specifically a directory with a known structure. It bundles the Library (the code) together with the Module (the interface) and Resources (images, storyboards, localization strings, and so on). Apple operating system utilize frameworks because they provide a single, portable, self-contained unit that includes everything a user needs…

…bounds” error instead of silently corrupting memory. Strict Type Safety: Swift is a strongly typed language. This helps prevent assigning an Int to a String type. Features like these make Swift a safe and productive language to work with. They eliminate many low-level issues that can cause problems…
