This is my personal and subjective summary of Apple’s keynote and state of the union during its worldwide developer conference 2024.

Breaking down individual features of domain-oriented managers into dedicated implementations improves developer experience.

Some SwiftUI views I have require padding one platform and none on the other. To avoid preprocessor switches everywhere I created a custom view modifier for it.

We need file provider extension processes to talk to each other. What first appeared to be prevented by sandbox on iOS works with a different API.

Having a file provider extension with multiple domains and processes and even more enumerators logging in parallel can become a mess. Leveraging the subsystem and category fields to the rescue.

Apparently, the feature set of fileproviderctl has been narrowed down to the dismay of developers, testers and even administrators and it appears to be intentional.

Out of necessity I created a minimalistic SwiftUI app which performs MD5 hashing to get a rough feeling how efficient it is on Apple devices.

I need to maintain a virtual file system in a CoreData database. Setting up test scenarios is tiresome, so I made use of result builders and its nice.

There is a better way than to repeat the same or similar NSPredicate all the time and it is very nice to read.

I rarely need to use defer blocks and mostly it is for ending signpost intervals. I checked the possible situation of having multiple and in which order they are executed.
