Hi, I am trying to list available contexts (it should have native_app, a UIWebview and a WKWebview), however, I was hitting errors as below:

And today, I got latest code and try to list all contexts, it's showing me "undefined method `contexts' for #Appium::Driver:0x007f7fc8ac8f38 (NoMethodError)"

So what's the right way to list all the contexts now and how shall I switch to the WKWebview context... Thanks for advice!

Can you give the logs for the undefined problem with the latest code? That should not happen.

@imurchie sorry it's my typo.. so I am still hitting the previous issue: Could not connect to a valid app after 20 tries.

Some more updates.. so it turns out that the issue happens only when appium driver is launched with udid capability:

so for an example,

this works:

desired_caps = {
    caps:       {
        platformName:  'iOS',
        automationName:'xcuitest',
        deviceName:    'iPhone 6',
        platformVersion: '9.3',
        app:           APP_PATH
    },
    appium_lib: {
        sauce_username:   nil, # don't run on Sauce
        sauce_access_key: nil
    }
}

but this DOESN'T work:

desired_caps = {
    caps:       {
        platformName:  'iOS',
        automationName:'xcuitest',
        deviceName:    'iPhone 6',
        **udid: 'a defined udid',**
        app:           APP_PATH
    },
    appium_lib: {
        sauce_username:   nil, # don't run on Sauce
        sauce_access_key: nil
    }
}

I won't say it's a major issue, however, it will be nice to be able to specify a udid in case we want to test multiple apps on same device. Also it seems just need an easy fix to populate platformVersion from the device(udid)... Thank you for help!

Interesting. Ok. I will look into what is going on here. Thanks for the updated information!

Alrighty. I can reproduce. Working on a solution.

I've tracked down the issue. It is when the remote debugger does not have a platformVersion. The quick solution is to pass one in in the desired capabilities.

I've also created a fix, which gets the pv from the device. Travis is being slow so it will take a little bit of time to get it through the build and into a release.

appium-xcuitest-driver 2.0.10 has a fix for the issue. Can you try that out?

For some reason I thought we had made platformVersion a required capability? i guess not

I thought we had, too. But apparently not.
