请教一下，当我同时需要同步私有库和公共库的时候，应该用哪种写法呢？

这两种哪个是正确的呢？还是都不正确？

Hi @DLsunset, the second one is the preferred way and the first one won't work as you expected. However, I suggest you put private/public model into different Realms and pass Realm configurations into the SyncObject initializer. I'll produce a detailed usage in the README later. Thank you!
