Until a change is made in the source code for Kodi you have to make a couple changes in code...
First off, you have to change the bundle identifier from org.xmc.kodi-tvos to something unique
This is under the main project settings in Xcode for both the Kodi-TVOS and TVOSTopShelf targets
Then, go into the capabilities tab and then expand App Groups... uncheck group.org.xbmc.shared
You then need to create a new app group, you can call it whatever you want but it has to be unique as well (in the format of group.*)
Then you need to modify the following files so that group.org.xbmc.shared is replaced with the security group ID that you created
- xbmc/platform/darwin/tvos/TopShelf/ServiceProvider.m, lines 48, and 53
- xbmc/platform/darwin/tvos/TVOSTopShelf.mm, lines 70, and 73
Do note, these line numbers will most likely change as development goes on... but that's where they are as of this post
And memphiz, feel free to correct me if there's any errors in these instructions... (I've never compiled the tvOS version myself...)
