What is the expected lifecycle of SWINject Graphidentifiers

Question

I'll start my saying that I'm inexperienced with Swinject.

I'm trying to figure out why Swinject.graphIdentier instances are constantly growing in my app.

In my case when I enter a ViewController I create n instances of MyClass. n can be a different amount each time the screen is visited.

When I leave the view controller all instances of MyClass are deallocated (proven by observing allocations profiler).

The thing that I don't understand is why instances of Swinject.graphIdentier continue to grow.

Should GraphIdentifers in swinject ever be cleanedup and if so how can I do that?

Below is a stripped down, contrived example of my code.

 class MyClass {
    
    }
    
 container.register(MyClass.self) {_ in
        return MyClass()
    }
    //Graph Identifier Count goes up
  func addItems() {
      let newItem = AppAssembler.resolver.resolve(MyClass.self)
      items.append(newItem)
   }
    //Graph Identifier count never goes down
  func removeItems() {
     items.removeAll()
   }
