Feature request: Add Traits to attributes on iOS

[d4vidi]

Describe your idea

Following an internal thread, there is a use case where the native selection state might be of interest. On xcode, that semantically shows under the Traits field (see image), which hints of that it might be possible to retrieve that through code.

@asafkorem would love to discuss this when you're available.

Will be supported in post-XCUITest support (Detox v21)

Will this also include traits like "Enabled" which is currently (v20) not supported while the negative "notEnabled" variant is?

Being able to check for

expect(element(by.id('my-button').and(by.traits(['button', 'Enabled'])))).toExist();

instead of the less reliable:

expect(element(by.id('my-button').and(by.traits(['button', 'notEnabled'])))).not.toExist();

In the first case it is clear the button is there and is disabled.
In the latter it could be missing for different reasons and the check is therefore less helpful.
