Bridging Swift Types to Objective-C
Wow! Great advice on how to keep writing amazing Swift code with the best of Swift features (yay enums and structs!) while still stuck in a hybrid Swift / Objective-C app.
Since we’re anticipating our entire codebase to move to Swift over time, we shouldn’t compromise our new types for bridgeability. Instead, let’s create a wrapper type..."

Build an iOS, watchOS and tvOS framework with a dependency using CocoaPods
One of my biggest goals for the try! Swift App was extracting the data layer into a pod that could be used across iOS, watchOS, and different extensions that I plan to make. But my data layer included a Realm dependency, which I had trouble connecting due to my limitations of knowledge of creating CocoaPods.
Anyway, I asked @aaalveee to help, and he wrote up how he did it! Here is the current trySwiftData pod that works across platforms and includes Realm (thanks @TimOliverAU!). More cool stuff to come there!

Swift 4: Release Process and Phase 2
The super big news here is that ABI stability has been deferred:
Deferring ABI stability enables Swift to focus on language fundamentals. An ABI dashboard will be wired up from the Swift Evolution Github repository. This will present a table of remaining ABI tasks and display their status.
Ownership Manifesto
Super important read - might need to read a few times 🤓
"The widespread use of copy-on-write value types in Swift has generally been a success. It does, however, come with some drawbacks..."
"Ownership is the responsibility of some piece of code to eventually cause a value to be destroyed. An ownership system is a set of rules or conventions for managing and transferring ownership."

On Open Source
Open Source Guide - A community guide for open source creators.
I remember when I first started coding, for a while, I thought people who contributed to open source were some sort of magicians way beyond my skill level. But I soon learned that even updating a README is a HUGE help to any project. And small changes really add up to make a great big project! Anyone can contribute! Thanks Github for putting this together 🐙
