How do I use @dynamicMemberLookup and @dynamicCallable in Swift?

The Swift programming language provides powerful features like @dynamicMemberLookup and @dynamicCallable that allow for more flexible and dynamic usage of types. Using these features, you can create types that respond dynamically to member and callable functionalities.

// Example of @dynamicMemberLookup @dynamicMemberLookup struct DynamicMemberLookupExample { subscript(dynamicMember member: String) -> String { return "You accessed: \(member)" } } let example = DynamicMemberLookupExample() print(example.someDynamicProperty) // Output: You accessed: someDynamicProperty // Example of @dynamicCallable @dynamicCallable struct DynamicCallableExample { func dynamicallyCall(withArguments args: [String]) -> String { return "Called with arguments: \(args.joined(separator: ", "))" } } let callableExample = DynamicCallableExample() print(callableExample("arg1", "arg2")) // Output: Called with arguments: arg1, arg2
