I’m playing with Platformer example.
I’ve created ipa file via Project / Bundle / iOS Application.
When I try to install the ipa, I get the below error:
platformer.ipa cannot be installed on Alex’s iPhone.
platformer.ipa does not contain an application bundle
How do you try to install it? XCode, Itunes, ios-deploy?
I can really recommend ios-deploy as a tool to quickly install an IPA from a terminal.
I try to install IPA file in XCode / Devices.
P.S.: I’ve tried to install in iTunes too. Unsuccessful.
This sound like a typical provisioning profile error, checkout this thread: Unable to install iOS Application from Defold (SOLVED)
And also I would like to repeat my suggestion of this little plugin: https://github.com/chockenberry/Provisioning 
It’s a defold bug
