I have installed the Realm Objective C Framework (2.0.3) by simply dragging it into my project created in Xcode 8. When I first tried it on simulator I got the typical dyld error.
dyld: Library not loaded: @rpath/Realm.framework/Realm
Referenced from: /var/containers/Bundle/Application/89F5987A-F3F0-45F2-9014-6BA662135E00/RelamDemo.app/RelamDemo
Reason: image not found
You need to ensure that
Realm.framework is also copied to the 'Embedded Binaries' section of your app as well.
You can find that section in the 'General' tab of your project's settings.
