Has there been any update with this issue? Is there a way to change the mode programmatically? Thanks.

Thanks for the quick response. I did try some of you mentioned, but right after posting I noticed that my Xcode is at 15.2 (~1 year old). -Who checks versions when everything is automated...? Steps I just completed: check the App Store, Sure enuf its at 16.2, but that version is not in my "update" list in the App Store. checked the MAC OS and applied the latest update to Ventura 13.7.4. After boot to updated MACOS, still can't update Xcode from the App Store....So I do the manual download from Apple of the .zip file and I get the : "You can’t use this version of the application “Xcode.app” with this version of macOS." So that also explains when I can't update to IOS 18.3.1 to support my iPhone development. Which Im not sure why my other projects still build and run on my iPhone...but haven't cleared the build dir's of those projects. So it looks like I have a reason to buy a new MAC or is there another workaround?

My dev env is back. I performed the following to get things operational (until I upgrade the MacPro: 1 uninstalled Xcode 2 manually delete everything in ./Library/Developer 3. Download Xcode 15.1 and CLT for Xcode 15.1 4. Reboot the MAC 5. Install Xcode 15.1 and CLT for Xcode 15.1 Do the verifications: $ xcode-select -p /Applications/Xcode.app/Contents/Developer $ pkgutil --pkg-info $(pkgutil --pkgs | grep CLTools | head -n 1) package-id: com.apple.pkg.CLTools_SDK_macOS13 version: 15.1.0.0.1.1700200546 volume: / location: / install-time: 1739554570 $ date -j -r 1739554570 Fri Feb 14 12:36:10 EST 2025
