Realm itself only adds less than 1 MB extra in your final app :-)<p>On Xamarin.iOS the Realm static libraries for all the iOS platforms and architectures we support are embedded inside the Realm.dll assembly. During build, Xamarin extracts the static libraries and links the app against them.<p>We should be more explicit about the size implications to avoid that chocking misunderstanding! We will update our FAQ.<p>Re. POCO support: We expect to support that going forward - you can follow the issue here: <a href="https:&#x2F;&#x2F;github.com&#x2F;realm&#x2F;realm-dotnet&#x2F;issues&#x2F;529" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;realm&#x2F;realm-dotnet&#x2F;issues&#x2F;529</a>.<p>Let us know if you have other questions or concerns! Github issues is a good place to suggest features or ask questions.<p>Thanks!
