What is the purpose of using autoWebview capability in Appium especially for iOS (with webviews)?

If you are testing Hybrid Apps, which are basically 100% webview, it can be inconvenient to remember to switch to using the Webview Context before every test. Sending the autoWebview capability tells appium to automatically switch to the WEBVIEW_CONTEXT as soon as the test starts. Appium also adds some additional logic for waiting until the webview has loaded, which can be a common source of errors.

Example:-capabilities.setCapability("autoWebview", true);
