@ObservableState in UIKit

[nmalevich]

I have explored migrating guide and projects from examples, but I haven't found answer for my question about observe{} and ObservableState.

For what we can separate observe{} if all of our separated parts of observe execute when we change only one property in ObservableState

I believe in their videos about Observability, they say it's okay for certain actions to be executed multiple times (like setting a button's attributes to the same value), which is why it should be okay to just utilize one observe closure in your code.

The exception is for computationally-intensive code like reloading a UITableView's data, in which case you do want to have that in a separate closure.

Hi @nmalevich, this is discussed in the docs here:

Generally speaking you can usually have a single observe(_:) in the entry point of your view, such as viewDidLoad for UIViewController.

...

However, if there is heavy work you need to perform when state changes, then it is best to put that in its own observe(_:).
