How to get @class DiaryEntry and @property to work in EntryViewController using Swift instead of Objective-C

Need some help to get through this, I am trying to build this app in swift as I learn through your videos in Obj-C.

The app is stuck at a point where clicking on an entry to edit does nothing. No errors, compile/runtime but I believe something is wrong with how I could not recreate a forward class declaration for THDiaryEntry and the entry property in Swift.

I did follow the interoperability method given in apple docs to create header file and utilize Bridging-Header in order to get the @class/@propert work in swift as a workaround but I am not able to get visibility for both in EntryViewController.

Any help is much appreciated.

Make sure your project recognizes your newly created bridging-header file as THE bridging-header file. Go to your target -> build settings -> in the search field type "bridging header" -> make sure your file is being displayed as the value for key "Objective-C Bridging Header". If not, change it to your file.

Thanks Stephen, I did try that and the auto-complete while using the entities created in the header file never seemed to work. Alternatively, I chose to use a nested struct to create a class type/variable (do let me know if this is an acceptable practice).

However, I am still stuck with the problem where clicking on an entry in the RootViewController does not take me to the "edit" view. Some print statements later, I see that the segue.identifier is coming through as nil. I checked/rechecked/recreated the segue with the identifier "edit" which is being evaluated in the prepareForSegue but no luck yet.

Thoughts?
