[iOS] Clicking on a button is success but nothing happens on the UI.

[pothurajtharun]

Do I have the most recent component updates?

• I use the most recent available driver/plugin and server versions

Is the component officially supported by the Appium team?

• I have verified the component repository is present under the Appium organization in GitHub

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

After clicking on a button the response is 200 but nothing has happened on the UI.

Expected Behavior

After clicking on the button it should navigate to the next screens.

Minimal Reproducible Example

The issue is reproducible only on iOS and in android works fine on clicking same button it navigates to other screen.

No response

Further Information

I tried both the w3c-actions and xcuitest-tap operations and nothing helped. Attaching logs for both the scenarios.

appium-xcuitest-tap.log

Nothing happened could indicate low level XCTest framework did click event, but the app did not receive such an event, or soemthing.

I found out some logs like below on your attached one. Touch event occurred on the testmanagerd level, so as Appium/XCTest perspective, it worked. mobile:tap log also looks similar

Possibly you could try out vanilla XCTest for UI if it has different behavior. The low-level should be the same/similar, so I guess it also behaves as same.

[pothurajtharun]

Thanks @KazuCocoa for quick response. The app is developed with flutter framework. On the same screen there are two button Next & Skip. As per this flutter buttons Next button is Filled Button and Skip button is Text button.

Click on Next Button works fine and navigated to other screen but clicking on Text button nothing happens.

Could you please help me with some pointers/examples how to use vanilla XCTest for UI and click on the element ?

Thanks!

[KazuCocoa]

Some online resources would help, for example. (random pickup here)
In the Flutter framework, the behavior could depend on how the Flutter/DartVM behaves for the iOS native's event. No surprise if it does not work then. (I saw a similar report somewhere before, which might not be Appium-specific)

[pothurajtharun]

@KazuCocoa, does the vanilla integration is possible with appium ?

I mean the app is launched with appium and perform the click action on the skip button with vanilla? Please let me know. I will try it later.

Thanks!

[KazuCocoa]

It is separated from Appium. You may need to write launching the test app etc with the XCTest project
