Xcode 16.3 beta Predictive Code Completion not working

With MacOS Sequoia 15.4 Beta (24E5206s) and Xcode 16.3 beta (16E5104o), Predictive Code Completion no longer works. Prior to the update, (as of yesterday) completion worked under Xcode 16.2 and MacOS 15.3 Beta. The models are already loaded.

So far, I've found the Predictive Completion to be useful in some situations (eg multiple cases in a switch), variably reliable in others (eg code suggestions in a CoreData stack) and downright wrong & annoying in others (eg referring to functions / modules that don't exist).

Could you try restarting your Mac, and seeing if that makes a difference? If not, please file a bug report with an Xcode sysdiagnose included so that we can look into this further.

hi michaela, what exactly is broken? any sample to share?

There is no code completion, predictive or otherwise, when typing code in Xcode: it's as though the feature has been completely turned off.

I'd tried turning off / back-on code completion etc in Xcode settings, then reloading the models - still didn't work. But restarting the Mac thereafter did, so thanks Ed. I should have thought of that.
