How do I declare a class level function in Swift?

Yes, you can create class functions like this:

class func someTypeMethod() {
    //body
}

Although in Swift, they are called Type methods.

You can define Type methods inside your class with:

class Foo {
    class func Bar() -> String {
        return "Bar"
    }
}

Then access them from the class Name, i.e:

Foo.Bar()

In Swift 2.0 you can use the static keyword which will prevent subclasses from overriding the method. class will allow subclasses to override.

UPDATED: Thanks to @Logan

With Xcode 6 beta 5 you should use static keyword for structs and class keyword for classes:

class Foo {
    class func Bar() -> String {
        return "Bar"
    }
}

struct Foo2 {
    static func Bar2() -> String {
        return "Bar2"
    }
}
