Is it possible to inherit a structure from multiple parents?

No. In Objective-C and Swift, structures do not support multiple inheritance.

Swift structures have significant capabilities, including protocols, extensions, methods, computed properties, stored properties, and initializers.

However, to achieve similar goals, Swift uses:

• Protocols: Define a set of requirements (methods, properties, initializers). A type (structure or class) can conform to one or more protocols, thereby acquiring their behavior.

// Protocol example
protocol Animal {
    var name: String { get }
    func makeSound()
}

// Structure conforming to protocol
struct Dog: Animal {
    let name: String

    func makeSound() {
        print("Woof!")
    }
}

• Extensions: Add new functions to existing types without modifying their original code.

// Example extension for String
extension String {
    func reversedWords() -> String {
        let words = self.split(separator: " ")
        return words.reversed().joined(separator: " ")
    }
}

// Usage of extension
let sentence = "Hello world"
print(sentence.reversedWords()) // Output: world Hello

Classes in Swift support single inheritance from one parent class but can implement multiple protocols.
