I've learned not only about Swift in this series, but also a lot about Taylor Swift too! :)

Thanks for all the videos; they're clear and succinct. Is there one on initializers on the horizon?

It's so funny to spectate how poor Paul struggles with a Butterfly Keyboard on his MacBook: constantly typing "m, " every time he wants to type just a coma, or "sGtring" (yeah, "G" is close to "T") and retYurn (for the same matter). I feel ya, man. Happens to me (and millions of others) all the time. It feels kinda good while watching these struggles, first, because it shows you do all of this kinda "live", second, it gives something to relate to, makes you (a Pro Swift guru) relatable to your newbie watchers and third, just feels good to see a proof that this is a keyboard issue, not your pointless fingers'.
