In our last eastside meeting for 2019, Chris Laurel will talk about "Nothing: Understanding nil, Void, and Never in Swift". Here is his description of the talk.
"This presentation will be a fun exploration of Swift’s different concepts of nothingness. We’ll look at some seemingly esoteric language constructs and use them to develop a deeper intuition for Swift types—features that may at first glance seem absurd end up being important for Swift’s safety and expressiveness. Only a basic familiarity with Swift is assumed, so while we’ll touch on some advanced ideas, novices should have no trouble following along."
Please send a meetup message to Ram (https://www.meetup.com/xcoders/members/158938212/) if you'd like to speak a future meeting. You could either do a lightning talk (~10 minutes) or a longer talk for 30-75 minutes.
