Hey Brian thanks for the awesome course!
I see that now you have icons under the project, however their files names are still strange, like "4d860822-2a26-42ed-91f0-9a971494ffdd.png", which still needs to be renamed manually. What I've been doing before this, is downloading the project, then going into "Assets.xcassets" folder and picking them one by one into my "Assets.xcassets" folder.
Since you're providing the assets from now on, can you instead just zip those images and attach the url for zip with images? That will allow us to drag and drop the files. Thanks again!
