How do I handle platform-specific differences with @available and #if?

In Swift, platform-specific differences can be effectively managed using the `@available` attribute and conditional compilation directives such as `#if`. The `@available` attribute allows you to specify the minimum platform version for which a function or feature is available, while `#if` can be used to conditionally include or exclude code based on compilation conditions.

Here's a simple example demonstrating both `@available` and `#if`:

// Example of using @available and #if in Swift import Foundation // Check for platform availability @available(iOS 14.0, *) func newFeature() { print("This is a new feature available in iOS 14 and later.") } #if os(iOS) func platformSpecificFeature() { print("This is specific to iOS.") } #elseif os(macOS) func platformSpecificFeature() { print("This is specific to macOS.") } #else func platformSpecificFeature() { print("This platform is not supported.") } #endif // Usage if #available(iOS 14.0, *) { newFeature() } else { print("You are using an older version of iOS.") } platformSpecificFeature()
