Open recent projects menu item no longer exists in new versions. Only on welcome. Steps to Reproduce: Launch Xcode 26.6 on macOS 26.5.1 Open an existing .xcodeproj or .xcworkspace file by double-clicking in Finder Close the project Open the Welcome window (Shift+Cmd+1 or via Window menu) Expected Result: The recently opened project appears in the Recent Projects list. Actual Result: The Welcome window shows "No Recent Projects". The keys IDERecentEditorDocuments and IDERecentWorkspaceDocuments in com.apple.dt.Xcode.plist remain empty or absent after opening projects. Diagnostic Steps Already Taken: Confirmed com.apple.quarantine xattr removed from Xcode plist Confirmed Full Disk Access granted to Xcode Confirmed plist is writable (no uchg flag, correct ownership) Deleted com.apple.dt.Xcode.plist entirely and allowed Xcode to recreate it — issue persists Confirmed ApplePersistenceIgnoreState is not set globally or per-app Confirmed NSGlobalDomain ApplePersistenceIgnoreState is not set Projects are opened by double-clicking physical .xcodeproj files in Finder (not aliases or symlinks) Environment: Xcode Version: 26.5 macOS Version: 26.5.1 (Build 25F80) Hardware: MacBook Pro
