Inheritance in Swift allows you to create a new class based on an existing class. When you inherit from a class, you can override methods to provide specific implementations for the subclass. It's important to use overriding safely to ensure that your code remains predictable and adaptable. Below are some best practices and examples for using inheritance and overriding methods in Swift.
class Animal {
func makeSound() {
print("Generic animal sound")
}
}
class Dog: Animal {
override func makeSound() {
print("Bark")
}
}
class Cat: Animal {
override func makeSound() {
print("Meow")
}
}
let dog = Dog()
dog.makeSound() // Output: Bark
let cat = Cat()
cat.makeSound() // Output: Meow
