Inconsistencies from the session

I ran into three and a half separate issues while following this code along.
  1. The first is that the spicy label had a vertical alignment issue between the text and the symbol. Apparently this is a known issue:

A Label used with a symbol image might appear misaligned. (60193698)

2. The second was that the toolbar instructions, as described in the video, did not add items to the navigation bar, but instead created a toolbar at the bottom of the screen.

This has a workaround from this answer, but the "half problem" is that with the workaround, the add button only temporarily appears before disappearing upon scene render. This happens on both Catalina and Big Sur.

3. I tried to build a Mac version, but it ended up with a window that won't enlarge beyond a size roughly twice as tall as just the titlebar, and maybe 300 points wide. The macOS preview within Xcode was also quite botched.

I'm not certain if these are my fault (I don't think any of them are) or if they are just prerelease issues. Any insight would be wonderful.

As a side note, these visual descriptions are flaky at best. We really should have a way to attach images, videos, or even just misc files here.
The second issue is most certainly a bug as well since I've been able to replicate it with a few machines running both Catalina and Big Sur. Not sure about the third issue since I'm not developing macOS apps at this time.
