How do you make a static class in swift?

I want to create a static class in swift, is this possible? If so how?

I tried:

static class MyClass

but get the error Declaration cannot be marked 'static'

static means no instance, so I would make it a struct with no initializer:

struct MyStruct {
    @available(*, unavailable) private init() {}

    static var foo = "foo"

    static func doSomething(a: String) -> String {
        return a + foo
    }
}

There's no static class, but you can make one by just adding static methods only.

The problem is that (as of today) classes cannot have static properties, so you have 2 options:

  • use a struct instead of a class, defining all its methods and properties as static
  • use the singleton pattern

The second option is in my opinion a better solution, unless you have specific reason for not wanting it.
