Does not support Realm Sync

[WarSunsOfPeace]

I tried to add through SWP and got errors with Realm Sync code. I know this is because it is not supported in the SPM build of Realm yet. I was able to grab the file from src to get it tor work but maybe another way of building would support this. I use Carthage instead of Pods when it is not supported by SPM so maybe adding this as a supported build type would work?
