Cannot find interface declaration for 'Object', superclass of 'Track'; did you mean 'NSObject'?

[bipinvaylu]

I am integrating RealmSwift framework to my OS X project.

import RealmSwift 
public class Track: Object {
    // class members and functions
}

I changed Track class to extend Object instead of NSObject, I am getting this error in ProjectName-Swift.h

@interface Track : Object

I am using CocoaPods for dependency management. I did googling for this issue but didn't get much.

Added RealmSwift dependency like this

pod 'RealmSwift'

I am using: XCode 7, Swift 2.0, CocoaPods

Generally the automatically generated Objective-C compatibility header shouldn't cause issues with integrating with CocoaPods. Which version of CocoaPods did used? As a workaround, you could just disable for now the generation by setting the build setting SWIFT_INSTALL_OBJC_HEADER to NO, because we discourage using RealmSwift in mixed setups, where Objective-C is used alongside to Swift to access the model. But I guess from the dependencies you show in your project navigator that this is more a pure Swift project, so the workaround could be applicable.

thanks @mrackwitz, i am using CocoaPods 0.38.2 and not following you where do i need to set this. SWIFT_INSTALL_OBJC_HEADER to NO, If possible can you please guide me.

[mrackwitz]

Sure, go into the build settings of your app target, copy the name of the build setting into the search field and then you can just select No as value from the combo box.

Thanks, I did that changes, clean and rebuild but still same issue, It's still generating same ProjectName-Swift.h file. I am having ProjectName-Bridging-Header.h file. I am using some swift classes in Obj-C code.

[mrackwitz]

So if your model classes should be among those classes used in Objective-C or the used classes depend on them, then you can't really use Realm Swift in this setup and would need to inherit from RLMObject instead.

Thanks @mrackwitz

    override public static func primaryKey() -> String? {

Just initialising model

let trackMetadata = ServerTrackMetadata(cueType: Type.Start, cueTime: 1234, createdBy: 1234, apiVersion: 1, hotcue: 123)

As this error isn't related to your previous issue, I'd prefer if you'd open a new issue with that error. This makes it easier in the future for other users to find help by existing issues. Nevertheless I don't think that the specific model and the crash are directly related. From the stack trace, I'm pretty sure It's caused by initializing your first model instance, which triggers the lazy-loading of the schema. It seems like you defined a property as Swift array e.g. linkedObjects = [Foo](), which doesn't work for several reasons. Instead you've to define your to-many relationships with the provided List-type e.g. linkedObjects = List<Foo>. Is my assumption correct and does that help? Anyway please open up a new issue, and copy-paste your question over there, I'll take care of moving my comment over as well and provide you further guidance as needed.
