Huge news for anyone working in tech in the US.

Noncompetes are now banned: not just in California (like before), but nationwide. Very, very relevant for anyone at Amazon (which is the Big Tech that has enforced noncompetes even for low-level engineering positions).

Swift 5.9 is now available! This is a major new release that introduces macros to Swift, adds bi-directional interoperability with C++, and more. Read the blog post to see what's new. https://t.co/JAklmUEylH

@everton_dev Just to add to the discussion, here's one example: https://t.co/atmQI9jiDq

@themarkvillar @everton_dev No, it won't. It'll only copy if you change it somehow: https://t.co/atmQI9jiDq

💡 Model you state using Swift enums. Use this technique to organize your SwiftUI code:

✍️ Hey iOS devs, I just published an article about the SwiftUI environment lifecycle.

❓Is it possible for it to be retained in memory? When does it happen?

https://t.co/bK144WrbKB

[Tiago Lopes @TiagoMaiaLopes]

@mitt_rafael If it's a published property, any changes to it would be emitted by its underlying publisher.

You get access to an environmentObject using the @environmentObject wrapper:

@environmentObject
var someEnvObj: SomeType

Changes to this object will all be observed by SwiftUI.

[Tiago Lopes @TiagoMaiaLopes]

@mitt_rafael An envObject might be used in all subviews, and changes to it might be still observed in different points:

RootView (contains envObj)
All subviews will have access to envObj
All subviews might redraw when envObj changes

[Tiago Lopes @TiagoMaiaLopes]

@mitt_rafael Minor correction:

In the first example, you can use:
envObj.$somePublishedProperty.sink {}

[Tiago Lopes @TiagoMaiaLopes]

@mitt_rafael It depends on what property is being published.

If you wish to manually observe events, you use the projected value: $somePublishedProperty.sink {}

If no published properties are exposed, you can use:
envObj.objectWillChange.sink {}

[Tiago Lopes @TiagoMaiaLopes]

@mitt_rafael SwiftUI automatically listens for updates of objects in the environment, and redraws itself when necessary.
