There are so many amazing WWDC sessions. I probably have 50 favorited on my  TV đ¤Š.
Here is one persons’ brave attempt to collate the best 15 ever, found on iOS Dev Weekly.
đ The 15 Best WWDC Videos of All Time
I genuinely appreciate the attempt, but I am perplexed that Protocol and Value Oriented Programming in UIKit Apps or Designing Fluid Interfaces didn’t make the list. đ¤ˇđťââď¸
Swift UI is ’s new declarative way to create apps across all its platforms. Time to dig into it!
Official tutorials from  – essentials, drawing and animation, app design and layout, framework integration
SWIFTUI BY EXAMPLE – highly recommended by iOS Dev Weekly
A good example of some synchronized / asynchronous programming in Swift, using an Operation subclass with OperationQueue.
đ Download files sequentially using URLSession inside OperationQueue
I like this article because it is practical, focused, and relatively simple. Via iOS Dev Weekly.
Meta-programming for Swift, stop writing boilerplate code
đ Sourcery
I haven’t tried this yet, but it sounds interesting if you find yourself writing repetitive code and can’t find another way around it. I gather it generates code from some sort of template.
Sourcery is a code generator for Swift language, built on top of Apple’s own SourceKit. It extends the language abstractions to allow you to generate boilerplate code automatically.
Holy crap, there’s finally a dedicated iOS API (NWPathMonitor) that detects and monitors network status!
đ Detecting Internet Access on iOS 12+
We’ve been dealing with or avoiding the problem of network connectivity on iOS apps for years. Now you can monitor the network status with a callback sort of like you would with location or other services. And you can specify wi-fi or cellular.
I’m glad this finally made it to the to of Apple’s backlog! đ
