So I asked the integrated AI a question and the answer was just some hallucination. Now that's nothing new. But the AI then proceeded to apply those hallucinated changes to my code base. Luckily I had no uncommited changes and could use git to revert those multi file changes. But it could have easily been different. So what did I do wrong? Did I click something? Pressed the wrong key? Don't want to happen this again and possibly destroy work.

Sadly my app doesn't look too good with the new sidebar style and currently I don't have the time to redesign it. (That will come later). When using Xcode 26 is there a way to keep the sidebar behavior but use the old Sequoia look? I initialize my sidebar splitview item with NSSplitViewItem(sidebarWithViewController: - when I switch to a different inititalizer (contentlist, inspector) it looks OK but the sidebar behavior (tracking toolbar item) is gone and the toolbar looks broken. Any other way to keep the old style besides not upgrading to Xcode 26? (The friendly integrated AI hallucinated some BS and then somehow applied those changes to my code ... luckily I had no pending code changes and could just revert via git).

So I tried changing the price for my app (which was roughly 12 hours ago) and the price just doesn't change in the Mac App Store. It was an immediate global price change (so no scheduling). I checked the price from a fresh VM so it's not a caching issue. Anyone got the same problem?
