To create a build for tvOS, go to Build Settings (menu:** File > Build Settings). In the Platform list, select tvOS, then select the Switch Platform button.
Similar to iOS, building your application to a tvOS device involves two steps:
tvOS build settings are the exact same as those for iOS. See iOS build settings to check which settings you can configure for your build.
Unity uses the incremental build pipeline when it builds the Player for tvOS. This means that Unity incrementally builds/generates files such as Information Property List (plist) files and Entitlement files. If you implement callbacks that modify or move any iOS file or asset that the incremental build pipeline uses, see Creating non-incremental builds.
