How to access back bar button item in universal way under UITests in Xcode?

Question

The problem is when I try to access back bar button item because it is presented with:

Like it is on the screens:

Currently I access it like this:

let backButton = XCUIApplication().buttons["Restaurants"]

but it won't work for other cases. It is not universal way. May I somehow set it accessibilityIdentifier or something else?

Setting the accessibility identifier is the most robust way as it will give you independence from the label text. — Lance Kind, Sep 30 '18 at 19:18

Generally the back button tends to be the first button element in the navigation bar

app.navigationBars.buttons.element(boundBy: 0).tap()

You can also add an accessibilityIdentifier to the back button when you're creating it (e.g., `backButton.accessibilityIdentifier = "back"`) and then you just do `app.buttons["back"].tap()`. – Aaron Sofaer Jul 28 '16 at 20:09

what if there is no back button and another button will be tapped? doesn't work well... need to assign identifier – Injectios Mar 21 '17 at 12:57

Based on Aaron Sofaers comment, you can also set the accessibilityIdentifier directly in Interface Builder.

Can you do this for the backBarButtonItem though? – skagedal Jan 17 '18 at 13:38
You should be able to do so, when you create it in a storyboard/xib. – d4Rk Jan 17 '18 at 14:06

Ah, but not programmatically? – skagedal Jan 17 '18 at 14:33
I don't think, you can access a programmatically created button in the Interface Builder?! – d4Rk Jan 17 '18 at 16:10
I mean, if I create the button programmatically and set the accessibilityIdentifier programmatically. I tried that and it didn't work. – skagedal Jan 18 '18 at 07:51
What did you do exactly? It should work, as Aaron Sofaer described it in his comment above. – d4Rk Jan 18 '18 at 10:09
This doesn't seem to work aqt least as of iOS 11 / Xcode 9. Asserting `button.exists` fails. – Nicolas Miari Feb 01 '18 at 03:09

Here's how you can do it in Swift 3:

app.navigationBars.buttons.element(boundBy: 0).tap()

What is the difference between this answer and the accepted one which was posted almost a year earlier? – lazarevzubov Aug 17 '23 at 08:54

Objective-C:

[[app.navigationBars.buttons elementBoundByIndex:0] tap];

Not the best solution because order of the buttons can be changed, and test case will fail. It's better to access the element using accessibilityIdentifier – Eduard Apr 19 '23 at 07:24
