How i start with Cocoa for Mac?

What would be the first places to get familiar with the development for Cocoa for Mac? I would like a tutorial, which executes the entire chain. Creating a project, edit 1 or 2 forms with the Interface Builder, a bit of interaction.

I come from Delphi and it’s all very confusing.

There are some videos on YouTube

I think its a good idea to understand a bit of the Objective C syntax so that you can read code because if I get stuck on something I usually hit stackoverflow or watch peoples videos on youtube.
