Static class in Swift

Question

I'v implemented a static TimeMonitor class in Java that look like this:

    public class SomeClass {
        private static ArrayList<String> _myList = new ArrayList<>();

        public static void add(String str) {
            _myList.add(str);
        }

        public static int getCount() {
            return _myList.length;
        }
    }

and I'm using it like this:

SomeClass.add("my string")

so when I'll call

int count = SomeClass.getCount()

The value of count will be 1

I do I implement the equivalent code in Swift 3?

I've found this question: How can I create a static class in Swift?, but I can't find a reference to an example that shows not only static methods but also saving static data as demonstrated in the Java example

Immediately off the top of my head, maybe something like...

public class SomeClass {
    internal static var myList: [String] = []

    public static var count: Int {
        return myList.count
    }

    public static func add(_ str: String) {
        myList.append(str)
    }
}

Then you could use it something like..

SomeClass.add("Hello")
let count = SomeClass.count

Equally, you could use a struct, since you can't really override anything, for example...

public struct SomeClass {
    internal static var myList: [String] = []

    public static var count: Int {
        return myList.count
    }

    public static func add(_ str: String) {
        myList.append(str)
    }
}
