The circle with a line through it is the icon you always get with .app files, so in this case it does not mean “no good” (I’ve never understood why they use that icon).
I’ve never used MacInCloud, so it’s difficult to tell if that’s where the problem lies.
When I build on my own Mac, this is the process to put a build onto my device, which works every time:
- Make app ID and provisioning profile on the iOS developer portal - make sure your device has permission to install app.
- Build app in Corona using that provisioning profile.
- a - Drop the resulting .app file onto the device using Xcode or
b - Place .app into a folder called payload. Zip that folder and rename to “MyAppName.ipa”. Drop onto device using iTunes or distribute for testing using Testflight.
That’s all I’ve ever had to do, without problems. The only thing I can see being the problem are either that the device hasn’t been ticked in the provisioning profile, or something in the process is being lost or performed incorrectly by MacInCloud.
