iOS in MAC

hello, I just buy my Mac Mini and I can build project fr desktop, web but when I try to build a iOS project the RUN and Build Button are disable. I have Xojo Pro.

Regards

You installed Xcode?

Just a watch for it in App Store.
On first start it may want to install some things…
That start Xojo and we hope it sees it.

Check Xojo requirements

If you have Xojo 2017r3 then you can use Xcode 9 from the App Store.
If you are using older version, you need Xcode 8.x from Apple Developers
