如何在macOS中的自定义视图中正确添加NSTextField的IBOutlet？

Question

I try to create an outlet from a NSTextView , which is a subview of my NSView derived custom class called GeneralView . I want to connect this outlet to my GeneralView class but Xcode doesn't like it. I get the following screen:

In this image, I want to connect an @IBOutlet from the NSTextField that contains '0000' to 'tfLiid' in GeneralView.

It only works if I create a @IBOutlet to the ViewController . But I have like more than 50 views (textfields, progress bars, checkboxes and so on...) I need to update, so I want to split those views in 3 parent views and keep the ViewController clean by holding only the 3 parent (or group) views.

The image below makes you understand more of what I tried to achieve (I hope).

I just don't know how to get this done right in Xcode, it's not a programming problem. Thank you.

I found a solution, just by experimenting trying out. I just couldn't let it go. Anyway, you have to drag from the little @IBOutlet circle (on the line number) to the view you want to connect it to. I don't know why the other way around doesn't work, there must be a reason for it.

An image below for a visual example:
