macOS tableView Delegate

[CylonGlitch]

I am following along in the Hillegass book and am at the section that teaches tableViews. I have so much working and everything seems to be OK, but I cannot get the delegate "tableViewSelectionDidChange" to fire. The book says that if it isn't being fired, it is either a misspelling of the delegate or the delegate outlet isn't setup. I know it's spelled right; so the outlet must be wrong. The problem is in the version of the book I have it doesn't match the version of XCode I am using and thus I am unsure how to correctly set the delegate.

Any suggestions? I'm a little confused here.

Ok, well, I figured it out. I had to create an outlet of delegate and then assign that delegate outlet to the main application and then it all worked well.
