After upgrading to Xcode 16.3, whenever I open the Documentation window, Xcode started CPU hungry mode, forever.

Does anyone else have the same experience as me? Is there any known remedy so far?

hi, issue is known, since beta3. [https://developer.apple.com/forums/thread/777010)

reported to apple via https://feedbackassistant.apple.com/feedback/16926964

and also already acknowledged in release notes for 16.3 [https://developer.apple.com/documentation/xcode-release-notes/xcode-16_3-release-notes#Developer-Documentation-Window)

workaround for mitigation is:

defaults write com.apple.dt.Xcode IDEDocumentationSpotlightIndexDisable -bool YES

Surprisingly, after disabling hotspot indexing, the world becomes peaceful and calm.

Now whenever I click a link in the quick help pane, the docs navigation pane immediately locates the context where the link is about. It had been non-functioning for the past several versions!
