Code To Reproduce Issue [ Good To Have ]

Here is the code for reference.

• Capabilities

'MutableCapabilities caps = new MutableCapabilities();
caps.setCapability("platformName", os);
caps.setCapability("deviceOrientation", "portrait");
caps.setCapability("browserName", browser);
caps.setCapability("browserVersion", version);
caps.setCapability("appium:deviceName", devicename);
caps.setCapability("appium:platformVersion", platformversion);
MutableCapabilities sauceOptions = new MutableCapabilities();
sauceOptions.setCapability("name", methodName);
sauceOptions.setCapability("appiumVersion", "1.17.1");
if (buildTag != null) {
caps.setCapability("build", buildTag);
}
caps.setCapability("sauce:options", sauceOptions);

		if (browser.toLowerCase().contains("chrome")) {
			ChromeOptions options = new ChromeOptions();
			options.addArguments("disable-translate");
			options.addArguments("disable-translate-new-ux");
			caps.setCapability(ChromeOptions.CAPABILITY, options);
		}

		// Launch remote browser and set it as the current thread
		webDriver.set(new RemoteWebDriver(
				new URL("https://" + username + ":" + accesskey + "@ondemand.saucelabs.com:443/wd/hub"),
				caps));
		`

Apparently, this same is working all fine for android but only for ioS there is this issue. What am i missing ?

This looks like an issue with the local automation script.

[sonali9293]

Could you tell me what changes would be needed? @mykola-mokhnach
@titusfortner - any thoughts?

[titusfortner]

@sonali9293 do you have a link to the test on Sauce that is failing?

We had a bug in beta version of Selenium 4 that would cause a problem like this when Sauce sent a redirect command (how it keeps the session open while it takes a while for a session to start), but that would be fixed for 4.1 for sure.

[sonali9293]

The current Selenium version that is being used is 4.1.0. Also about the link, I am not sure if you would be able to access it as it is under a group (). but If this helps, I have attached the logs and video for reference. @titusfortner

[titusfortner]

ok, @diemol just informed me that we only partially fixed it in the beta and we fully fixed it in 4.1.2, so upgrade your local Selenium and it should work.

[sonali9293]

This helped. Thanks a lot :). It is now initializing the driver for iOS correctly. But, seems like none of the latest selenium added features such as NewWindow, getScreenshotAs, or even relative locator is compatible wit IOS.
As we earlier discussed @titusfortner on this same, and an issue has been raised by you on the same and guess it is still in progress ( https://github.com/appium/appium/issues/16749 ). How long do you guys think will it take to be added ? @mykola-mokhnach

[titusfortner]

Relative locator should work, it's just Javascript execution underneath. The others are new endpoints and the various drivers need to add them as well, from what I understand.

Ah here: appium/appium#16749 (comment)

This might be chrome only, though.
