summary: "WebKit usage in CodexBar: WebView hosts, cookie stores, and teardown guidance." read_when:

  • Touching WebKit-backed login windows or offscreen scraping
  • Debugging WebKit teardown crashes (especially x86_64)
  • Changing WebKit window lifecycle behavior

WebKit usage

CodexBar uses WebKit in two places:

  • Visible purchase windows (e.g. credits purchase).
  • Offscreen WebViews for OpenAI dashboard scraping.

Teardown helper

Use WebKitTeardown whenever a WKWebView + NSWindow should be torn down or hidden. It centralizes Intel-friendly cleanup:

  • Stops loading and clears delegates.
  • Delays teardown so WebKit can unwind callbacks.
  • Keeps owners retained briefly on x86_64 to avoid autorelease crashes.

When to use

  • Any WebKit window that closes after a flow (login, purchase, etc.).
  • Offscreen WebView hosts that hide/close after scraping.

Notes

  • For login flows that persist cookies manually, prefer WKWebsiteDataStore.nonPersistent().
  • Keep window isReleasedWhenClosed = false when teardown is deferred.
  • Avoid closing WebViews directly; route cleanup through the helper.
