Are there access modifiers in Swift? (public, private, internal)

Hello everyone! I just started learning Swift, coming from Java and C++, and I have one question bothering me. In Java, I'm used to explicitly specifying `public`, `private`, `protected` before every class, method, or field. But in Swift, I see that in code examples they often don't write anything before the declaration, and it still works. For example: ```swift class MyClass { var name = "John" func sayHello() { print("Hello") } } ``` And I can access this class and its methods from another file in the same project. Does this mean that by default everything is `public`? Or is there some other default modifier? And how do I make something completely hidden inside a file or inside a class? I've heard about `fileprivate` and `open`, but I don't understand when to use them. Please explain what access modifiers exist in Swift, what their default is, and how they differ from Java.
