Bug Report

Problem

What is expected to happen?

click on input type=file and then choosing "do Photo or Video" should ask Permissions on first install and then open a camera.

What does actually happen?

on iPad no permissions for first install for back camera, if I switch to the front camera then I see permission dialog and can take image from front camera. Switching back to the "back camera" help me not. I see black screen.

On first click on input field I have 1-2s downtime and then in xcode logs this exceptions:

Environment, Platform, Device

• cordova v10.0.0
• cordova-ios v6.1.1
• node v14.15.4
• npm v6.14.10
• macOS Catalina v10.15.7 (19H512)
• Xcode v12.4 (12D4e)

Update:

after upgrading Xcode to v12.4 on iPhone 6s (IOS 13.2) the file-input started work as expected. I see permisison dialog on first start. Before Xcode to v12.4 was just black screen without any buttons and without permission. After restart App camera ask permissions and work. But this steps work not always.

currently on iPad Air 2 (IOS 14.3)

1. click on file-input
2. cordova open camera app
   
   Nothing happens
3. click on fron camera button
   
   cordova ask permission
   front camera work. Switching back to the back camera - black screen

Same for video settings. work only front camera.

click on "take image" button give me exception:

[Camera] No signpostID found for persistenceUUID C40227CA-9D4C-4F79-88AF-9ABFDA244EA8

Input file is handled by the WKWebView itself, not by cordova, there is nothing we can do.
For WKWebView issues, report them to apple directly on https://bugs.webkit.org/
