appium: Unable to find WEBVIEW context with iOS 13

The problem

I am unable to find WEBVIEW context using driver.contexts. It only shows [‘NATIVE_APP’] using get_all_context. I have no problem getting and switching to WEBVIEW using Appium 1.13 with iOS 12.0. However, recently I want to upgrade to iOS 13 using the latest Appium. I keep running into this problem.

Environment

• Appium version: 1.17.1-beta.0
• Last Appium version that did not exhibit the issue: 1.13 + iOS 12.0
• Desktop OS/version used to run Appium: MacOS 10.15.4 / Xcode 11.4
• Node.js version: 13.12.0
• Npm or Yarn package manager: 6.14.4
• Mobile platform/version: iOS 13.0
• Real device or emulator/simulator: iOS Simulator
• Appium CLI or Appium.app|exe: Appium CLI

/usr/local/lib
└─┬ appium@1.17.1-beta.0

Details

There is no issue with Appium 1.13 + iOS 12.0 switching webview in my app. I don’t know what I did wrong in this setup. I have already update everything to the latest version as I can. It seems like appium can not find any WEBVIEW at all, since I keeps getting only [NATIVE_APP]. I have tried:

1. Uninstall and reinstall appium CLI both 1.17.1 and beta
2. Add Capabilities like: ‘fullContextList’: True I am still unable to resolve this issue.

Code To Reproduce Issue [ Good To Have ]

    def switch_context(self, context):  # context = 'WEBVIEW' / 'NATIVE_APP'
        time.sleep(10)
        self.logger.info("[Automation Log]: before switch " + self.driver.current_context)

        while context not in self.driver.current_context:
            if context == "WEBVIEW":
                self.logger.info(self.driver.contexts)
                try:
                    self.driver.switch_to.context(self.driver.contexts[1])
                except BaseException as msg:
                    self.logger.info(msg)
            elif context == "NATIVE_APP":
                self.driver.switch_to.context(context)
