Class are being linked more than once in target

Question

I have two targets app and appTests. Also I have class Wine and framework Realm and 'RealmSwift' which are linked to those two targets. There is no exception When I use class Wine in traget app.

But when I want to run test like

appTests.swift (22 lines)

import UIKit
import XCTest
import RealmSwift

class appTests: XCTestCase {
func testRealmAdd() {
         NSFileManager.defaultManager().removeItemAtPath(Realm.defaultPath, error: nil)
        let realm = Realm()
        let wine = Wine() // when error occure
        wine.photo = "photo"
        wine.desc = "description"
        wine.raiting = 3.0

        realm.write { () -> Void in
            realm.add(wine)
        }

        let result = realm.objects(Wine)
        print("\(result)")
        XCTAssertTrue(result.count == 1, "There should be one element")
    }
}

Wine.swift (10 lines)

import UIKit
import RealmSwift

class Wine: Object {

    dynamic var desc: String = ""
    dynamic var photo: String = ""
    dynamic var raiting: Double = 0

}

Then an exception appear at line 8 in appTests.swift

RLMObject subclasses with the same name cannot be included twice in the same target. Please make sure 'Wine' is only linked once to your current target.

I already did clear DerivedData and project. Could You suggest where I should look?

EDIT after nhgrif comment

Ok it appears that an exception is rising earlier, in line 7. Which is now marked in code thanks to nhgrif.

Answer 1

Wine.swift should only be in app, and not appTests. Including it in both results in appTests having two classes named Wine (app.Wine and appTests.Wine), which is not something that Realm supports. As long as Wine is public (or in Swift 2.0, @Testable), you can access it from appTests without including it in the appTests target because appTests links in app.
