I’m at the very beginning (and already enjoy the course)–VARIABLES, it could’ve been overlooked or something I haven’t 'gotten" or gotten-to yet, etc. but:
In Swift concepts/theory/practice there are not ;'s [semi-colon] at the end of declarations. My first thought is Apple did away with them to save one step/nanosecond. CLEVER!
However, on ‘page 3,’ one of the hints shows the : at the end, though the examples do NOT have it.
I did check Swift.org and do not see them and I tried with and without it, both seem to work.
Please feel free to delete this or move it, if it’s not an error–I actually came here just to satisfy my curiosity but found this and … the rest is history.
PS Sorry I am rambling, I excited and been alone and quarantined since March 21!
