Issue #37
Hi there,
Welcome to the 37th issue ๐
Apologies for sending this issue a day late - I've had a small self-inflicted injury and had to go to the hospital just in case. All is well in the end though ๐
You might have noticed a different sender and layout this time - that's because I've switched from Revue to a content platform called Ghost. It's a really powerful platform, and I will be expanding the site, such as adding the ability to search among all past issues. Stay tuned :)
Structuring SwiftUI views
SwiftUI is relatively new, but there are other declarative UI languages with history. React is a popular web frontend framework, and there's a lot we can learn from there.
One example is a pattern where we break down views that load data into two:
The outer view is a loading component that's aware of the networking, and the inner view is a more "stupid" view with just UI elements.
The inner view then can then be reused - across features, for previews in app settings, and for SwiftUI previews.
ReactJS has a pattern called container and presentation components. This pattern suggest you fetch data + more in container component and pass it down to presentation components. Your presentation components are reusable components. #SwiftUI pic.twitter.com/5EMjfc2WUR

Organizing test image assets
Good tip here to avoid cluttering your app with images you only use for testing - saving on both app size and compile time:
Speed up your Xcode builds by leaving images for testing OUTSIDE of (Preview) Asset catalogs; just drop them in a folder among tests and fetch them via Bundle.

Project quality-of-life
Completely agree with the list here. When there's no warnings in the project, the console log isn't cluttered, etc - it's so much easier to spot new issues right when they are introduced:
Things that should be vigilantly defended in your iOS project, at all times:

- A working build
- Clear build output (e.g. warnings)
- Clear console behavior
- NO Auto Layout warnings
- Any CI/'CD' systems
All are easy to let deteriorate, yet, critical day-to-day. Fix it early.

Excellent article to understand the various cache policies and how they affect your iOS application when sending HTTP requests with URLRequest:
