Run button greyed out

Hi,
I have recently upgraded to the latest Xojo 2018.r.1.1. I run it on a Mac Air 11" early 2016. I have Xcode 8.3.3…

I have just made the first attempts on a new app and wanted to run it to de-bug… However, I cannot press the “Run” (or “Build”) button. It worked before in the earlier version of Xojo. I may have overlooked something important but I can’t figure out where. Is it in the Xcode set-up?

Best regards,
Kristian

Probably yes. Check that you have the appropriate command line tools selected in Xcode preferences and that you defined at least one Simulator device.

Also make sure that you’ve started Xcode at least once to accepts the EULA…

I am not sure Xojo 2018r1 works with Xcode 8.

You should try with Xcode 9 if the above suggestions have no effect.

EDIT: if your app is for iPhone, only Xcode 9 will produce an app that is fully compatible with the larger iPhone X screen.

I have the same problem: have started to write an Xojo 2018 1.1 iOS app, but can’t run it. Xcode 9.4.1 with simulator 11.3 loaded, as well Command Line codes from Apple Download 10.13.beta installed.
What else am I missing to solve this?
Where is it described that the Run button can even be dimmed??

Hey, I resatrted my Mac: and Run in Xojo is not dimmed out anymore…
