How to compile an app on Xcode without developer account
Try changing the identifier to something unique to you, like &quot;net.plato.kodi-ios&quot; and then try having Xcode fix the issue.
I eventually got Kodi to compile on my own after tweaking some of the provisioning settings, but I have active developer profiles and haven't ever done anything with the free account.
There have been limits on the number of free apps you can sign. See this link to stack overflow if you run into errors.
