Great!. I just noticed that the original did not hit the use list. I composed that on my phone and it seems that email account will not post to the lists anymore. I'll get Heather to fix that. One addition... The alligator (OldXcodeVersions folder) should be nowhere near the applications folder. Preferably "in a galaxy far far away". My First stab was as a sub-folder in applications. I had a problem (could/could not have been related). I moved OldXcodeVersions folder to the desktop and there it stays.

This works! Very easy once you know the location of the alligators in the swamp.

After fiddling around a bit, LC 8.2.6 would no longer launch the simulator. I get the following error message on all versions, no matter what I put into the LiveCode preferences for XCode:

Is it ok to have all of them in my applications folder, then enter them into the LC Preferences->mobile Support pane? Or will it mix up software from different versions of XCode in my app folder?

I did note that there was a red/green box in the LC mobile support pane in preferences, which should indicate the all the XCode support files are correct for the running version of LC. This doesn’t seem to be the case, though. It does respond to the version loaded, though, which is something.
