I want to create entity from dictionary using MR_ImportFromObject method. It worked before I update Xcode 6 to 7. But when I use Xcode7, ImportFromObject method is not working. Every call that method, willImport Delegate method is not called and application is crashed.

But ImportFromArray method is working very well.

Here is error message. I think the points are "swift_bridgeNonVerbatimFromObjectiveC" and "value type is not bridged to Objective-C".

I changed the MagicalRecord MR_importFromObject Library for now from 

id value = [objectData MR_valueForAttribute:primaryAttribute];

if (primaryAttribute != nil)
 {
      managedObject = [self MR_findFirstByAttribute:[primaryAttribute name] withValue:value inContext:context];
 }

to

 if (primaryAttribute != nil)
 {
   id value = [objectData MR_valueForAttribute:primaryAttribute];
            managedObject = [self MR_findFirstByAttribute:[primaryAttribute name] withValue:value inContext:context];
 }

You can probably put this in a category or extension (swift) on NSManagedObject and use that until MagicalRecord fixes this. That's what I'll do. This fixed this crash for me.

Try disabling the swift compiler optimizations. We had a similar crash unrelated to magical record that was fixed by changing that setting.
