BoogieBot File Error

Hi, I am new to Swift and I am following the Intro to App development with Swift guid.

I practice the lessons on Xcode Version 10.0 (10A255).

On lesson 7, once I open the BoogieBot file I get this error:

“kCAAlignmentCenter' has been renamed to 'CATextLayerAlignmentMode.center”


I have no idea what that means or what I should be doing.


I also can’t get the live view to work in the assistant editor. I followed the instructions provided in the lesson file, but I can’t get the assistant editor to show the playground’s timeline, I only have “Live View” at the top, but there is nothing called “Time Line.”

First things first, the

kCAAlignmentCenter

Thanks for your reply. I went to the link you provided, but when I checked xCode I didn't get the option to fix the issue when I pressed on the red error symbol.

This is what fixed the isseu. On the Books app I downloaded an update to the Intro to App Development with Swift book. Within the updat I was able to download an xCode 10 project files. When I opened the BoogieBot file from there I did not have any issue.
