Hi, I am installing my Xojo Pro license (2017 2.1) on a Mac Pro running High Sierra. I have installed the product and installed Xcode 9.1I have obviously missed something because I can’t run or build my project - Is there any documentation out there that will cover the installation.
if you are talking about an “Xojo for iOS” project, it is because Xojo requires Xcode 8
and does not currently work with Xcode 9, and mentioned on numerous topics on this forum
what kind of project ?
if its iOS Xcode 9 is not supported yet

I removed Xcode 9 and installed Xcode 8.3.2 however there is no change - I still can’t run or build the Eddies Electronics application. I’m obviously still missing something. What??
did you try to run Xcode8…
to make sure it was in fact installed properly
and to let it gather all the other bits it sometimes requires…
Go to xcode preferences…
Click on locations…
Check if "Command Line Tools: " is stating 8.x.x or select it.
Restart Xojo
It seems to be resolved - you are correct in that Xcode needs to run rather than sit in its welcome screen. Thanks to all.
Will I have to deal with this if I let my Mac upgrade to High Sierra even if I do not use the iOS module?
Xcode and Xojo are only related for iOS projects… not for macOS Desktop projects
so no, you won’t need to deal with it 
Good. Thanks, David, as usual.
