No targets found, when switching from app to browser on iOS

The problem

Sometimes you need to automate the following flow

1. login to a native app
2. after login you need to pay something and a link in the app opens a browser
3. the browser needs to be used to pay
4. after payment the browser is opening the app again
5. the payment in the app is processed

This is currently failing at step 3 with the following error Encountered internal error running command: Error: No targets found, unable to communicate with device

Code To Reproduce Issue [ Good To Have ]

I’m using WebdriverIO and the Sauce Labs sample app to execute the test, the test executes the following steps:

// config
config.capabilities = [
    {
        // The defaults you need to have in your config
        deviceName: 'iPhone X',
        platformName: 'iOS',
        platformVersion: '12.2',
        orientation: 'PORTRAIT',
        // The path to the app, see https://github.com/saucelabs/sample-app-mobile/releases
        app: join(process.cwd(), './apps/iOS.Simulator.SauceLabs.Mobile.Sample.app.2.1.0.app.zip'),
        // Read the reset strategies very well, they differ per platform, see
        // http://appium.io/docs/en/writing-running-appium/other/reset-strategies/
        noReset: true,
        newCommandTimeout: 240,
        maxInstances: 1,
        fullContextList: true,
    },
];

describe('Appium', () => {
    it('should be able to work with the browser that is opened with the app', () => {
        // Login to the app and verify that it succeeded
        LoginScreen.waitForIsShown();
        LoginScreen.signIn(LOGIN_USERS.STANDARD);
        InventoryListScreen.waitForIsShown();

        expect(InventoryListScreen.isShown()).toEqual(true);

        // Open the menu and click on the about screen
        Menu.open();
        Menu.openAbout();

        let webviewID = {};

        driver.waitUntil(() => {
            const contexts = Context.getCurrentContexts();
            webviewID = contexts
                .filter(context => {
                    console.log('filter context = ', context)
                    return !context.id.includes('NATIVE_APP')
                })
                .find(context => {
                    console.log('some context = ', context)
                    return context.url.includes('https://saucelabs.com/')
                });
            return webviewID || false;
        }, DEFAULT_TIMEOUT);

        driver.switchContext(webviewID.id);

        expect(browser.getTitle()).toEqual('Cross Browser Testing, Selenium Testing, Mobile Testing | Sauce Labs');
    })
})

@wswebcreation Can you try the latest beta of Appium, and add the includeSafariInWebviews capability (set to true) to your desired caps for the test?

Retested this with Appium 1.15.0-stable and it works like a charm, thanks for this!!
