Does not support Realm Sync

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?
