I’m really looking forward to learning this and figuring out why my constraints get out of whack after re opening a project. I was following another tutorial and everything seemed ok until I closed the project and reopened it, then got the “Horizontal position is ambiguous” warning on a button. This was not present until I re opened the file. ---

Hello, can I ask how you are zooming in and out in steps on the Main.storyboard (Preview) ? Mouse clicking in the white area only gives two options , zoom in or out, thank you for any feedback. Xcode 8.3.1 ---

I use a pinch gesture on my trackpad for zooming. ---

Interesting! I didn’t know anything about trackpads. I’ve seen others doing the same and it was driving me nuts because they never mentioned how it was done. Thx! ---

Hi, I have a paid subscription but when I go to download materials all I get is a PDF of the slides, not the demo code. How do I get the demo code? ---

When I download the material, I see pdfs and project code. Can you try the download again and let me know if you’re still having an issue? ---

This only happened on the first lesson. I guessing there was no project files for that.
