iOS 13.3 Appium not responding after switchContext to WebView

The problem

Appium stops responding after attempting to switchContext(‘WEBVIEW…’).

Environment

• Appium version: 1.16.0
• Node.js version: 10.17.0
• Npm: 6.13.3
• Mobile platform/version under test: iOS 13.3
• Real device or emulator/simulator: Simulator
• Appium CLI or Appium.app|exe: CLI via webdriver.io

Details

In my setup I have a cordova app that successfully installs and launches. When attempting to switch to the webview context, Appium stops responding. The POST requests to /context time out.

Might be a wdio thing but if I enter debug first (browser.debug()) and browser.switchContext('WEBVIEW...') no response is received, further commands are ignored.

This issue does not occur on an iOS 13.2.2 simulator. Here’s how to install older simulators if you need to get around this.

Similar to #13361 and #13799 but they’re running older iOS versions.

Code To Reproduce Issue [ Good To Have ]

This is using the wdio cli with Mocha. You probably get the idea of what it’s doing otherwise.

let pollCount = 0;
const pollForWebview = async () => {
    const contexts = await browser.getContexts();
    const webContext = contexts.find(context => context.startsWith('WEBVIEW'));
    if(webContext) return webContext;
    if(pollCount < 3) return browser.pause(1000).then(pollForWebview);
}

describe('app:', () => {
    it('loads', async () => {
        console.log('hello!');
        const webContext = await pollForWebview();
        await browser.switchContext(webContext);
        const context = await browser.getContext();
        console.log(context);
    });
});
