Explore logging in Swift - A nice walk through on how to use os_log. I've always thought that Console App is one of the nicest log viewers out there.
Embrace Swift type inference - Talks about the improvements on the type inference in Xcode for Swift 5.3.
What's new in Mac Catalyst - More information on how Catalyst can be used to improve performance with the new App life Cycle matching iOS on macOS.
Sync a Core Data store with the CloudKit public database - The sync is easy due to the similitudes between Core Data and CloudKit. Also expllains the differences between the two, and how can they share data.
Refine Objective-C frameworks for Swift - Talks about useful annotations to help Swift interface well with Objective-C code. Also about how you could use some Swift code to improve the usability of your Objective-C frameworks. Very informative.

Use Swift on AWS Lambda with Xcode - Interesting example of how to use Swift to build serverles functions. The code seems straightforward when we are dealing with the simple case that our serverlless functions are closures.

Networking
