Do variables in AppDelegate put a workaround for a static variable in Swift?

Since Swift has no static variables, and I'm trying to access a connection, which should be static ... puts this variable in the App Delegate with a reasonable solution?

I found this snippet on GitHub :

func xmppStream () -> XMPPStream {
    return appDelegate().xmppStream!
}

So, when xmppStream()called in code, does it return the original instance or what is actually done here?

This is not entirely accurate. Swift CLASSES do not have static variables, but structures and enumerations do!

struct Static {
    static var stream: XMPPStream?
}

And you can initialize it later in your code if you want.

Static.stream = XMPPStream()

, , , :

class RegularClass {

    struct Static {
        static var stream: XMPPStream?
    }

    //Other code
}

, ...

RegularClass.Static.stream ...

, , Swift. .
