Swift: CarPlay crash with Dynamic Actor Isolation

We recently noticed a CarPlay crash in our app piling up that started appearing after we released app version 3.2.0. There were no compiler errors or warnings associated with the troublesome code, and we didn’t touch the implementation either. Let’s look at the issue together.

A few months ago, I started building CiderKit.Tween, a #Swift6 package dedicated to animation and tweening in particular.

For my fellow #Unity game devs, think DOTween but for #Swift and #SpriteKit.

Version 0.5.0 has been released with several new additions.

#Development
After a busy period with the #SwiftyNetworking refactor, Im now back in @commitphotos with performance tweaks. 🔧👨‍💻

I thought the project was ready for #Swift6, not now. The plan is simple - to start a solid promo and have an update ready at the end of the month. 📸

How do you bridge the gap between legacy Apple APIs and Swift 6's strict concurrency model?

𝑀𝑎𝑖𝑛𝐴𝑐𝑡𝑜𝑟.𝑎𝑠𝑠𝑢𝑚𝑒𝐼𝑠𝑜𝑙𝑎𝑡𝑒𝑑 provides a MainActor context within synchronous methods, solving compatibility issues with APIs like 𝑁𝑆𝑇𝑒𝑥𝑡𝐴𝑡𝑡𝑎𝑐ℎ𝑚𝑒𝑛𝑡𝑉𝑖𝑒𝑤𝑃𝑟𝑜𝑣𝑖𝑑𝑒𝑟 and 𝑈𝐼𝐻𝑜𝑠𝑡𝑖𝑛𝑔𝐶𝑜𝑛𝑡𝑟𝑜𝑙𝑙𝑒𝑟. This is essential knowledge for Swift 6 migration!

🚨 BREAKING: Swift 6 introduces "typed throws" to make error handling *typesafe* and *user-friendly.* 🚨 Because, apparently, developers were just tossing random errors around like confetti at a tech conference. 🎉 Next up: Swift 7 - a guide on how to use a keyboard. 😜
