Under the hood of Futures & Promises in Swift
Great explanation of what a promise vs a future is and how they work in Swift:
"A Promise is something you make to someone else."
"In the Future you may choose to honor (resolve) that promise, or reject it."

Swift Evolution
Swift 5: start your engines
The biggest news here is that ABI stability will be a requirement for Swift 5:
"First, ABI stability is the center focus of Swift 5 — and we will pivot much of our prioritization of efforts for Swift 5 around it. With Swift 4, ABI stability was a strong goal. In Swift 5, it is a requirement of the release. Whatever ABI we have at the end of Swift 5 is the ABI that we will have. ABI stability is an important inflection point for the maturity of the language, and it cannot be delayed any longer."
In addition, the Swift evolution process is changing in a big way. All Swift 5 proposals must have an implementation before they are officially reviewed by the Core Team.
"An implementation can come long after an idea has been pitched and after a proposal has been written. However, before a pull request for an evolution proposal will be accepted — and thus an official review scheduled — an implementation must be in hand for a proposal as part of the review. The existence of an implementation does not guarantee that the proposal will be accepted, but it is instrumental in evaluating the quality and impact of the proposal."

Working with CoreNFC in iOS 11
CoreNFC hasn't gotten as much attention since WWDC, but is something that is a big deal to finally have an API for and could open up a new class of interesting applications:
"Here’s a practical use-case: You run a shop and want the customers to just walk in, scan an item using NFC, and walk out. There’s no hassle and no wait time. As an app developer, without access to NFC, the second best thing would probably be bar-codes or QR-codes, but that’s annoying and takes a lot more work to scan.
So, what’s the catch? Though Apple finally opens up the NFC reader, the company strictly limits our access. This means
CoreNFConly supports the NDEF format mentioned earlier. If you are planning to useCoreNFCto replace your RFID iClass cards (a commonly used format in business security cards), think again."
