Thought it would be nice to have an errata thread since I found one, and it might not be the last one to be found. (Hopefully we won’t have too many.)
SBUBaseMessageCell.message is implemented as an optional, but the reference says it’s a non-optional field.
To be honest I think it should be a late-init property (implicitly unwrapped optional) if anything, but it’s what it is.
Also, there are quite a few public properties missing for the said class, so maybe you guys have to regenerate the docs to match the latest release.
