Does Swift follow the “typical” order (from what I’ve heard)? That is, parentheses first (obviously), then NOT (I’d think it’s because it’s next to what it negates), then AND, and finally OR?

In lesson 6, the comment at the top says to make each variable true (but you’re supposed to make bool3 false!). However, there are two places in the lesson that say otherwise. I was able to achieve the correct solution, but it was still a bit confusing. This should be fixed.

I understand how && favors FALSE and || favors true but the below example page 6 of 7 ; makes no sense to me or when i would ever use this for an app? please help:

let bool1 = (true || false) || false || false

let bool2 = !true || (false && false || true)

let bool3 = !(false && true) && (false || false)
