PyObjC Error: Exception during dealloc of proxy

[chdominguez]

Specification

• pywebview version: 4.1
• operating system: macOS Monterey 12.6.5
• web renderer: Cocoa / Qt

Description

After setting up my pywebview project, I compiled some React code which works perfectly on the browser (Safari/Chrome) but, when running in pywebview I get the following error in the terminal when using Cocoa:

PyObjC: Exception during dealloc of proxy: Completion handler passed to -[BrowserDelegate webView:didReceiveAuthenticationChallenge:completionHandler:] was not called

Then some of the features coded in React won't work. I have searched in the pyobjc repo about this but I did not find anything meaningful. When using Qt I do not get any error in the terminal but React code does not work as expected also.

Practicalities

• YES I am willing to work on this issue myself.

• NO I am prepared to support this issue financially.

Okay so I fixed it by installing the whole pyobjc library. By default while installing pywebview, it only installed:

• pyobjc-core
• pyobjc-framework-cocoa
• pyobjc-framework-webkit

I ran pip install pyobjc and it fixed the issue after installing all the pyobjc modules. I suppose that not all of them are needed, but as a quick fix this works.

pyobjc-framework-security is a missing package that fixes this problem. I will update pyproject.toml
