问题
I'm a newbie iOS developer and trying to implement device to device notification in iOS something to handle friend requests etc.. I'm looking for documentation that guides me in the process. I'm using firebase as my backend system but I'm cannot find any documentation about device to device notification . I also checked out One Signal but still having hard time figuring out how this is implemented , Can anyone point me in the right direction

You'd need to implement this logic with server-side code using one of Firebase's server SDKs. You can look their fantastic documentation to learn more.
