Delegate returning nil value

Using Swift
1

I have tried to use a delegate to talk between different SKScenes and for some reason am returning a nil value when called:

protocol RemoveListEntry : class {
    func removeItemInList()
}


class List {

    func removeItemInList() {
        print("remove item")
    }
}


class Menu {

    var entryRemovalDelegate : RemoveListEntry!
    
    
    let listEntryRemoval: Button = {

        let button = Button(imageNamed: "button", title: "Remove Entry", buttonAction: {
            let listEntryRemoval = Menu()
            listEntryRemoval.removeEntry()
        })
        button.position = CGPoint(x: 0.5, y: 0.5)
        button.name = "listEntryRemoval"
        return button
    }()
    
    
    func removeEntry() {
        
        print("value: \(entryRemovalDelegate)")         //why is this nil, it will not pass ?
        if let removeEntry = entryRemovalDelegate {
            removeEntry.removeItemInList()
        }
    }
}

The idea is to click a button and have it execute on another scene, but the "entryRemovalDelegate" is a nil value, and so the function is not called.

I think your delegate is supposed to be weak (and then you can also skip the if let check). Also, can you double check if you’re actually setting the delegate property?
