Escaping and Nonescaping Closures in Swift 3
"When you pass a closure into a function in Swift 3, there’s a new wrinkle: the compiler assumes closure parameters are non-escaping by default. What does this mean? What’s the difference between an escaping and a non-escaping closure?"
Thanks for explaining this @gregheo! This is definitely one of those topics I have to keep looking up!
It’s Now or Never…
Never is a new keyword in Swift that could sometimes be used instead of @noreturn. Good explanation of what it does and the comparison to @noreturn. Another example here. My guess is that I'll Never use this 😁

Swift: Custom Fonts. Slightly Less Awful.
Custom Fonts with Dynamic Type supported - a very nice huge improvement to the ugly string-based UIKit implementation 👏

Random Cool Stuff
A mistake is just a moment in time
Absolutely love this story about Navajo rugs that have mistakes woven into the patterns:
"He said the mistakes weren’t intentional. What was intentional was the desire not to go back and fix them."

MC-ing try! Swift NYC
I'll be honest - while I'm fine giving technical talks, MC-ing is absolutely terrifying for me. Even doing the opening and closing speeches at try! Swift NYC completely drained me. That's why I asked @allonsykraken and @catehstn to co-MC! Oh, and there was a magician to re-energize the audience as well!
But even so, I had no idea how much work being an MC is than just the terrifying part of being fun on stage while introducing the speakers. Love this write-up by Cate on how much thought she put into being an MC and all the additional behind-the-scenes work involved 💜💜💜

Type Erasure Magic
MUST WATCH!!! Unfortunately generics won't be fixed until Swift 4.0 (or later), so learning this workaround is crucial when working with protocols with associated types for now. This talk gives a clear and easy-to-understand example!
Become a Better Engineer Through Writing
An absolutely delightful and powerful talk from @kristinathai on the importance of writing as a software engineer! I got to watch it live the first time, and I'm so happy it got recorded this second time for everyone to see!

Copying
Absolutely beautifully written!
"Sometimes life is not unlike programming. Who and what we choose to copy says a lot about us. Choosing to use someone’s idea is still a choice. Give credit to your inspirations, but don’t discount the wisdom in picking something beautiful to copy."
Business
What I Learned From 10 Years of Doing PR for Apple
"Most importantly, respect your brand. That’s the biggest lesson of all that I learned at Apple. It’s your biggest asset and you have to protect it. Think twice before giving away your products in a raffle. Think carefully about what other brands you associate with."
Swift Thoughts
It has now been over a week since try! Swift NYC and I'm still reeling with feelings of awe, inspiration, gratefulness, and love for the Swift community we're building! Thanks (I really wish there was a better and much bigger word than just thanks!) to all the volunteers, speakers, sponsors, emcees, and of course the attendees who made it such an incredible event ❤️
Now onto iPhone 7 and the removal of the headphone jack... I'm personally waiting for this gadget to come out first before getting the courage to commit to a life where I can't charge my phone and listen to my nice noise-cancelling headphones on an long flight. That said, the potential future does sounds cool...
And now back to our regularly scheduled programming 🚀
