This completely eliminates concurrent access and the low-level data races that come with it. “ Conceptually, an actor is an object that protects its own state by only providing mutually exclusive access. On Apple WWDC 2021, there is Platforms State of Union that take a deeper dive into the new tools, technologies, and advances across Apple platforms that will help you create even better apps. I dropped the ball a bit (mostly during the graphics/Metal portion). Actors are an industry standard and are vital to safe concurrent programming. Another quick list of topics from todays WWDC State of the Union presentation. Apple’s new approach to this is Structured Concurrency. The problem? Swift never had native support for concurrent code, so it was unnecessarily difficult to write good concurrent code.

“Concurrency enables your apps to perform multiple tasks at the same time, which helps your apps stay responsive to user input while doing work in the background, like a weather app fetching forecast data while the user selects a city.”

Most developers and engineers are used to the idea of writing concurrent code as it’s such a vital part of making fast and responsive code. Anyone who does code reviews how confusing it can get when there are multiple revisions and files removed or added to a pull request. The new views allow you to select between multiple ways to see what code has changed, and even view comments as you are fixing any potential bugs.

This actually seems like a fun way to write tests for your app!Ĭode reviews also look to make massive improvements on commenting and reviewing code. I can see how building apps this way is way more integrated and convenient. There is also a public API that you can dive into for grabbing information about your builds. One cool feature is that you can have the build notify you when it completes and publish it to your Slack or any other service. It publishes your result right back into Xcode’s report navigator so you never have to switch context out of where you are building your app. It helps you offload your builds, test, and code signing for distribution. A new continuous integration and delivery service built right into Xcode and hosted in the cloud, Xcode Build is Apple’s take on simplifying the process of building an app while helping you focus on what’s important.
