Fixed (as least to my config/situation). Note: Reverting the workaround: defaults write com.apple.dt.Xcode IDEDocumentationSpotlightIndexDisable -bool NO **Version 16.4 beta (16F1t) // 28 April 2025 ** Xcode now behaves as it should. The 'Developer Documentation' window can be called, a re-indexing takes place (indexing takes a few minutes, during this time Xcode consumes a few CPU cycles, but so far everything is acceptable). The indexing process is completed and a new directory has been created. /Users/username/Library/Developer/Xcode/DocumentationCache/v279 So far I have not detected any side effects or other errors. So far so good.

Hi @InstantInteractive as per May 15, the Xcode RC for 16.4 (16F6) --> WITH latest *.5 Releases is available for download: (this release is offering all relevant final version *.5 SDKs giving full platform support) [https://developer.apple.com/download/applications/) have fun! Cheers, /B

Hi, @Nickkk might be, that you are affected of a 16.3* Bug. see here: [https://developer.apple.com/forums/thread/777010) recommend to upgrade to 16.4 anyway because .3 has too many bugs. good luck and have fun!

Craig, it's you?

Hi Thanks for submitting the FB. Confirm here. Some kind of workaround fixed that for me: Via Project-Navigator select a source file and via the option-command-2-inspector-pane enable 'show history inspector'-pane. Once you see the commit info for this specific file, you can switch with command-2 to the source control navigator. Now every commit in the repo-history should be shown as before. This procedure did the trick for me. Up to now looks quite persistent (after quitting Xcode, reboot, relogin, etc.) everything is fine. update playing around with enabling code-review in editor seems also work and switching on the repo-commit-history list. have to correct: not really persistent fix. looks like it disappeared again. Oh, what a mess with Xcode B3. (Hope you) Have fun!

Hi, yes, it is already known, see here: [https://developer.apple.com/forums/thread/793582) no permanent fix for this is available (yet). For some workaround see the link above.

seems fixed with Xcode 26 beta 4. 😀

SOLVED … by myself. Resolution is as follows: In the Device and Simulator Windows (where currently my right-pane top-area is blurred), click context/right-click like with intention to customize toolbar. Then the pop-up for toolbar-customizing like icon-only, icon and text , text-only appears. Choose something other than icon and text (‘Icon and Text’ will blur the top-part!!!). e. g. with Icon only setting —> all looks fine as expected. So, Apple, please fix this, other users will also trap into this. Completion: Do not set Toolbar to ‘Icon and Text’ ps. I don’t know how this initially happened to me. No clue.

Here is the Link to get the latest Xcode 26. [https://developer.apple.com/download/applications/) Xcode 26 RC requires a Mac running macOS Sequoia 15.6 or later. [https://developer.apple.com/documentation/xcode-release-notes/xcode-26-release-notes) Have fun, and good luck. Cheers!

Hi there, confirm for macOS 26.3 Beta (25D5112c) that the Developer.app (1083.3.1) does now show the videos with fullscreen option. FIXED. thx and have fun
