I get so annoyed when I find myself using random websites 🤮 or all different apps 🤷🏻♂️ to do things like format JSON, test regex’s, encode/decode Base64, encode/decode URLs, or convert Unix time strings.
Developing features for a large, established app, I often run get slowed down trying to throw together a new screen. You have to find the right spot in the code to update, build the whole app (not just what you changed), log in, and drill down to the right spot to try out your creation. Something’s off? Do it all over again.
Which is why I love the idea of the Playbook library, which is “a library that provides a sandbox for building UI components without having to worry about application-specific dependencies.” Yass! 🤟

Updating UI on a thread other than the main thread is a common mistake that can result in missed UI updates, visual defects, data corruptions, and crashes.
And someone has put together a page documenting how to configure the Main Thread Checker for your own specific needs. It’s straightforwardly called Configuring the Main Thread Checker.

P.S. There’s another utility from Apple called Thread Sanitizer, to “Audit threading issues in your code”. 🤷🏻♂️
This looks like a great debugging tool if you’re doing some serious CoreData work.
