Summary:
One of the big announcements for the web in iOS 11 is support for getUserMedia in Safari (see https://developer.apple.com/library/content/releasenotes/General/WhatsNewInSafari/Safari_11_0/Safari_11_0.html#//apple_ref/doc/uid/TP40014305-CH13-SW8 for announcement).  Sadly, it appears that getUserMedia is not enabled for applications that use a WKWebView.

Steps to Reproduce:
Call `getUserMedia` in a page loaded into a WKWebView

Expected Results:
Access to the microphone and camera

Actual Results:
The API is not available

Version:
iOS 11 beta 4

We have same issue, and standard reply from Apple stuff - Duplicate of 29281220. We need this functionality for our app. Does anybody know when this issue will be fixed?

I managed to re-enable the API, in the context of cordova-plugin-wkwebview-engine, by using the private WebKit function: void WKPreferencesSetMediaDevicesEnabled(WKPreferences* preferencesRef, bool enabled)

Assuming you are using Objective C, to reproduce, you need 1. to declare this function, and 2 when you are setting up WKWebViewConfiguration, call it:

1.

void WKPreferencesSetMediaDevicesEnabled(WKPreferences* preferencesRef, bool enabled);

2.

WKWebViewConfiguration* configuration = [[WKWebViewConfiguration alloc] init]; ... WKPreferencesSetMediaDevicesEnabled(configuration.preferences, true);

However, the call getUserMedia fails with the error "SecurityError: The operation is insecure.". I did not manage yet to work around it.

Hi, Can you be more specific? Where should i declare the function WKPreferencesSetMediaDevicesEnabled(configuration.preferences, true); Thx

I did put it in that function: https://github.com/apache/cordova-plugin-wkwebview-engine/blob/6f468f48735c5937f497e6a851901d4f68ce7da2/src/ios/CDVWKWebViewEngine.m#L75
