I have exactly the same issue.
Appium version (or git revision) that exhibits the issue: 1.6.1-beta
Desktop OS/version used to run Appium: OS X 10.12.2
Node.js version (unless using Appium.app|exe): 6.9.1
Mobile platform/version under test: iOS 10.0
Real device or emulator/simulator: simulator
Appium CLI or Appium.app|exe: Appium CLI
Coding language: java-client 5.0.0-BETA1
I am upgrading from iOS 9.3 to 10.0. So I changed to xcode8 and got the new java-client.
I was frighten to have lot of problems with the migration from the uiautomation to the NSPredicats, but first there occurs some strange cast errors.
AppiumDriver<IOSElement> driver = new IOSDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
List<IOSElement> allTravelActions = driver.findElementsById("travelActions.title");
allTravelActions.get(0).click();
The last line with .click() leads to the following error:
org.openqa.selenium.remote.RemoteWebElement cannot be cast to io.appium.java_client.ios.IOSElement
And also in a for each loop this error occurs
ArrayList<IOSElement> top10list = driver.findElementsById("stationSearch.station.name");
for (IOSElement item : top10list){
}
Debugging shows me, that "driver.findElementsByAccessibilityId" returns a List of RemoteWebElements (screenshot01 + 02)
Why do I get RemoteWebElements from my AppiumDriver ?

@iriszhang1986
Guys, could you invoke the
driver.getSessionDetails()and show the result map here?
It is defenetely the bug but now I'm trying to get my local Mac machine fixed
At which place in the code?
AppiumDriver<IOSElement> driver = new IOSDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
driver.getSessionDetails();

@derunewige @saikrishna321 @SrinivasanTarget
It seemst that there are two problems.
The first problem is that we didn't expect that session can't contain any information about platform/automation. I think we can resolve it on the client side.
The second probled. Why does it not contain that info when app is started on a real iPhone/iPad? May be there is server side bug.
Any thoughts?
The first problem is that we didn't expect that session can't contain any information about platform/automation
All the details are received from server including the automation and platform and lot more. Sample response

let me try on real device
I see Automation Name or Platform Details is not coming up in session details at times when we run on XCUITMode (Only in XCUITMode) even on simulators.
@iriszhang1986 @derunewige Please do a run without below capabilities and send us entire server logs.
caps.setCapability(IOSMobileCapabilityType.AUTO_ACCEPT_ALERTS, Boolean.TRUE);
caps.setCapability(IOSMobileCapabilityType.SEND_KEY_STRATEGY, SendKeyStrategy.SET_VALUE);
caps.setCapability(MobileCapabilityType.NO_RESET, Boolean.TRUE);
caps.setCapability(MobileCapabilityType.FULL_RESET, Boolean.FALSE);
Between i'm debugging it as well.
@SrinivasanTarget @TikhomirovSergey with legacy driver i get the below response, which looks fine to me. May be as srini mentioned could be with XCUITest
public void iosSetup() throws MalformedURLException {
caps.setCapability(MobileCapabilityType.UDID, "xxx");
caps.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone SE");
caps.setCapability(MobileCapabilityType.PLATFORM_VERSION, "9.3.2");
caps.setCapability(IOSMobileCapabilityType.BUNDLE_ID, "xxx");
caps.setCapability(MobileCapabilityType.APP,"/Users/saikrisv/Downloads/debug.ipa");
driver = new IOSDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"), caps);
}
{"webStorageEnabled":false,"locationContextEnabled":false,"browserName":"","platform":"MAC","javascriptEnabled":true,"databaseEnabled":false,"takesScreenshot":true,"networkConnectionEnabled":false,"app":"/Users/saikrisv/Downloads/XXX-debug.ipa","bundleId":"XXX","udid":"XXXXX","platformName":"iOS","deviceName":"iPhone SE","platformVersion":"9.3.2","desired":{"app":"/Users/saikrisv/Downloads/XXX-debug.ipa","bundleId":"XXX","udid":"XXX","platformName":"iOS","deviceName":"iPhone SE","platformVersion":"9.3.2"}}
Yes it is fine in legacy driver and UIAutomator2 mode but Automation Name is not coming if we didn't specify it explicitly in desired caps and running on iOS10 sims.
@derunewige @SrinivasanTarget @saikrishna321
Ok. I can propose a PR. But there is some server side issue defenetely.
Good morning!
here is the server log without these four caps: gist
So it is only:
log.info("AppiumDriverBuilder: creating driver for iOS10 SIM environment");
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.IOS_XCUI_TEST);
caps.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.IOS);
caps.setCapability(MobileCapabilityType.PLATFORM_VERSION, "10.0");
caps.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone 7");
caps.setCapability(MobileCapabilityType.APP, "/Users/kevinbeschorner/Desktop/OEBB App.app");
caps.setCapability(IOSMobileCapabilityType.BUNDLE_ID, "at.oebb.TSMobileTesting");
driver = new IOSDriver<IOSElement>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
log.debug("Before printing session details");
log.info(driver.getSessionDetails());
log.debug("After printing session details");
Console log:
09:32:00.709 [main] DEBUG utils.AppiumDriverBuilder - Before printing session details

It is interesting, that without that four caps the browser name, or rather the app name, as well as the bundleID is not set when calling getSessionDetails()
I did an update from appium 1.6.1-beta to 1.6.3 and now it looks like it is working!
@derunewige Can you attach the latest logs as well here (1.6.3)?
Yes, of course: gist
Thank you all for your support!

@derunewige now it gets all the session details, @TikhomirovSergey can we keep this open as @SrinivasanTarget did see the session details missing on random calls
Yes @saikrishna321. Session details is a server issue but anyways we need a fix for this which @TikhomirovSergey is working on.
@derunewige @sravanmedarapu @saikrishna321
There is Installing-the-project. We recommend 1.6.3 or higher.
@SrinivasanTarget are session details missed randomly with 1.6.3?
@saikrishna321 If no, we can close this issue, if yes I will keep working on the fix. We could use capabilities if session details are missed.
@SrinivasanTarget are session details missed randomly with 1.6.3? >> It is missing only if you dont specify the Automation Name explicitly and run on iOS 10.
@TikhomirovSergey we need to keep this open and get the session details fixed if AutomationName is provided or not when running on iOS 10.
What say @SrinivasanTarget ?
Hey guys, any solution for this ? I met same problem... and my environment are as follow:
Appium: 1.6.4
Selenium/Grid: 3.2.0
Java-client: 5.0.0 BETA7
This issue got fixed in java-client-5.0.1.jar
