What have you tried? Tried simple tap by text “Allow” ?

driver.executeScript(“mobile: alert”, ImmutableMap.of(“action”, “accept”));

Earlier same code was working. After upgraded XCode 13.2 and both simulator and device getting this issue.

  1. try https://appiumpro.com/editions/31-automating-custom-alert-buttons-on-ios
  2. fail nr 1 -> switch to tap by text

driver.switchTo().alert().accept();

This one also I tried getting same error, also navigated to the element and tried calling click() event, then also failed

I use simple tap by text with iOS alerts.

Hey @KUMARAVEL-kg @Aleksei

I am also seeing the same issue, After upgrading to XCode 13.2. IS there any work around for it?

It’s a bug in iOS. See Error on click on location permission dialog on iOS 15.0

once again. i just use search element by exact name and it works without problem with 15.1 and 15.2

@iOSXCUITFindBy(iOSNsPredicate = "type == 'XCUIElementTypeButton' AND visible == 1 AND 
 (name == 'Allow While Using App' OR name == 'Allow')")

I wasn’t able to click the element directly, I got this error:

# Ruby bindings
@driver.find_element(:xpath, "//XCUIElementTypeButton[@label='Ask App Not to Track']").click
# throws this error:
# An unknown server-side error occurred while processing the command. Original error: *** -[__NSArrayM insertObject:atIndex:]: object cannot be nil

My solution was to find the coordinates for the alert button I wanted to tap and then tap on that specific location. I already had much of this code written in my appium interface, but perhaps this will help you:

def get_middle_coordinates(locator)
    location = @driver.find_element(locator).location
    size = @driver.find_element(locator).size

    x = (size["width"] / 2) + location["x"]
    y = (size["height"] / 2) + location["y"]

    return { x: x, y: y }
end

def tap_by_coordinates(x, y)
    Appium::Core::TouchAction
        .new(@driver)
        .tap(x: x, y: y)
        .perform
end

accept_alert_locator = { xpath: "//XCUIElementTypeButton[@label='Ask App Not to Track']" }
middle_coordinates = get_middle_coordinates(accept_alert_locator)
tap_by_coordinates(x: middle_coordinates[:x], y: middle_coordinates[:y])

I have same issue, and I fixed it by that:
public void clickSystemNotification(MobileElement element) {
Actions action = new Actions(getDriver());
action.moveToElement(getDriver().findElement(By.id(“Allow”)));
action.click();
action.perform();
}

The iOS bug you mentioned has been fixed in Appium 1.22.1 and 2.0.0-beta. be sure you are running one of those versions and you should be fine. Also, learn from my mistake and dont use the Appium Desktop app. For whatever reason, it is running v 1.22.0 and has this bug present.
Hope this helps someone.

A big thank you to you @catsandcode it took me 2 days to reach out to the solution which is provided by you, it works.
My IOS developer has to create a new label “label=“okBTN”” to facilitate this–> This thing I additionally need to do to resolve this issue.

But anyway thanks a lot.
