Start window without width in application using storyboard

Question

I am trying to understand Storyboard in Xcode. I created a new Mac OS X application from a template and defined a simple storyboard, as in the following figure:

The problem is that when the application starts, my window looks like this:

I need to resize it to see the RIGHT and LEFT part of the vertical separation. I also determined the height with my window, so I don’t know why this is happening, and I really don’t know why this window is correctly shown using the view controller below, and not for the split view controller.

What am I doing wrong with the split view controller?

Answer 1

The solution is to add width limits with a minimum width to the views on each side of the SplitView.

I got the idea of this answer to a similar question .
