If you upgraded to Xcode 16.3, be warned: there appears to be a simulator bug that causes network access to fail regularly. It doesn't affect devices, just the simulator. You can work around it by using URLSession(configuration: .ephemeral) rather than URLSession.shared.

In Swift, property wrappers let you encapsulate and reuse code for property storage and access. Rather than writing repetitive getter and setter logic, you define the behavior once in a property wrapper and apply it with a simple annotation.

Swift uses ARC for memory management, but handling strong, weak, and unowned references is key. Use weak for delegates and closures to prevent retain cycles, and unowned when the object outlives its reference. Master these practices to build efficient, reliable iOS apps. #Swift

Apple platform development has changed. Previously, we thought building an app’s core around UIKit and using SwiftUI for certain screens was good. This week, we’ll explore SwiftUI for app development and UIKit for scenarios where performance matters. buff.ly/VCspO7B

Swift uses type inference to determine variable types at compile time, reducing the need for explicit type annotations. The compiler infers types based on assigned values, making code more concise while maintaining type safety. #ios #swift

Closures in Swift are self-contained blocks of code that can be passed around and executed later. They capture and store references to variables from their surrounding context. Closures use {} and can be written in a concise form with shorthand argument names ($0, $1).

Swift’s optionals handle the absence of a value safely. An optional can either hold a value or be nil. Declare optionals using ? and safely unwrap them with if let, guard let, or ??. For forced unwrapping, use !, but be cautious as it may lead to runtime crashes.
