Thank you so much for you rocket response. I was able to see the socket connected for real device. Hence, I could see it in the connected device list.

However, I got another issue that after clicking on the connect device, it was disconnected and below was the log thrown:

@TuHuynhVan Please give the device information which you have used. We have tried this in real device and didn't face this issue. Device information will help us to debug it further.

I deployed on an iPhone 6S with below info:

		productVersion:             9.3.5
		buildVersion:               13G36
		deviceSoftwareVersion:      9.3.5 (13G36)

@TuHuynhVan Thanks for the info! We will test on lower OS versions and try to debug this issue.

[TuHuynhVan]

Thanks @shubhankaryash
I also tried on another my iPhone, with version 10.3.2. The socket could not connect...

[shubhankaryash]

@TuHuynhVan I tried this on iPhone 7 with 10.2.1. I was able to connect to the socket. Do make sure that your system and mobile are connected to the same network, have no proxy and the localhost has been replaced with the ip. As far as the crash is concerned, I will try to get an iOS 9 device and give an update.

[TuHuynhVan]

@shubhankaryash as your guess, the second iPhone (version 10.3.2) was not on same network with the node server. I changed it to the same and I was able to connect and interact with it.

The version 9.3.5 is still crashed...

Anyway, thank you and the team so much!
Even the interaction from Web UI is still slow (3s) but this is a significant movement!

Pls let me know what should I do for the version 9.3.5

[shubhankaryash]

@TuHuynhVan Glad we could resolve the iOS 10 issue. Rendering the screenshot from the device involves a lot of data being sent over the network. Hence it is still a bit slow even after the considerable optimisations we have done. We are still looking at solutions to compress this data and try to make this quicker.

I will inform you once I am able to get an iOS 9 device and test on it.

@shubhankaryash
Just wanna update, I just tried on another iPhone, version 11.1.2 is also OK! <3

@shubhankaryash
Can I just build the WDA on the target device then when I plug it into the host, I could see it connected from connected device list in stead of xcode test.... and keep the session in terminal?

And can I still run automation test (which requires WDA involved) on same target device?
I think I just need to use another port for WDA instead of 8000. Am I right?

Thank you so much!

[shubhankaryash]

@TuHuynhVan You always need to run the tests through XcodeIDE/XcodeBuild. Having it installed beforehand and running it wont work. As far as running multiple tests on a single device is concerned, I am not sure but I think you can check by running them through the terminal.

I tested it out on iPadMini 9.3.5 and like you said it crashed. We are getting the screenSize with 0 dimensions from the API FBApplication has provided.

[TuHuynhVan]

@shubhankaryash Thank you for your confirmation. Let me:
[1] build the WDA on the target iPhone
[2] start xcode test... from terminal (viewing screen/interaction from Web UI purpose)
[3] Start testing with Appium

To make sure that we can use the device for both purpose.

@Team, Greetings and congrats for successfully achieving this. I tried this to install on real device IOS Version 11.0.1. and able to install WD and able to build the project. But i could not see the device in the browser. It says no device. When i check the console i see the below error,

WebDriverAgentRunner-Runner[2838:17916155] Task <09BB3D98-698A-42E9-9576-E4683841A2A3>.<1> finished with error - code: -1001

Task <09BB3D98-698A-42E9-9576-E4683841A2A3>.<1> HTTP load failed (error code: -999 [1:89])

Seems like i could not connect to Socket. My phone and Mac is in same network. I tried multiple ways by turn the proxy off etc., but no luck. Requesting your support here.

I can see the Simulator without any issues. I have issues in real device only. Please help. Also mention what IOS versions are supported.
