Good article about comprehending mergeable libraries introduced a few weeks ago at WWDC.

We can now make use of mergeable libraries, which are a new type of library that combines the best of dynamic and static libraries. They are optimised for both build time and launch time performance and are designed to feel like static libraries.

Apple's just released a new, open source package designed to provide common types for working with HTTP. This package provides a convenient integration with Foundation as well. However, it's important to note that the current version of the package does have a limitation: it does not include support for HTTP request and response bodies.

I've attempted multiple times to access the tint or foreground color using the @Environment in custom components, but each time I ended up by passing this color through the initializer. However, I recently discovered a solution that seems to work seamlessly. For instance, a value set via the foregroundColor modifier can be easily accessed using the ForegroundShapeStyle (refer to the attached screenshot). The same approach can be applied to the tint color as well.

Friendly reminder:

From Fall 2023 you’ll receive an email from Apple if you upload an app to App Store Connect that uses required reason API without describing the reason in its privacy manifest file. From Spring 2024, apps that don’t describe their use of required reason API in their privacy manifest file won’t be accepted by App Store Connect.

p.s. User Defaults API is in this list as well.

So an author wrote a shell script that helps you to identify the use of such API in your code base.
