Core Data class and fetch request issue

I'm puzzled by an error using Core Data (XCode 7.1 / Swift 2.0)

The below code is working perfectly

class DB_PlayerData: NSManagedObject
{
    @NSManaged var playerID: NSNumber
}

class PlayerClass
{
    var IDPlayer: Int = 0
}

func test()
{
    let LocalAppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    let ManagedObjectContext = LocalAppDelegate.managedObjectContext
    var SelectAll = NSFetchRequest()
    var ResultatRecherche: NSArray = []
    var gPlayerData = PlayerClass()


    SelectAll = NSFetchRequest(entityName: eNomDBFiles.DB_PlayerData.rawValue)
    try! ResultatRecherche = ManagedObjectContext?.executeFetchRequest(SelectAll) as! [DB_PlayerData]
    if (ResultatRecherche.count == 1)
    {
        gPlayerData.IDPlayer = Int(ResultatRecherche[0].playerID)
    }
    else
    {
        // Do something
    }
}

But if the function test is not in the same swift file in my project as the DB_PlayerData class declaration, I get the following error: Value of type 'AnyObject' has no member 'playerID'

Entity has been created in the DB model in Xcode with name and class equal to DB_PlayerData and Module set to project name. I've tried all kind of setup options described here and there was no success.

Any clue why?

You havent told the compiler which type is enclosed in your array.

    var ResultatRecherche: [DB_PlayerData] = []

instead of 

    var ResultatRecherche: NSArray = []

I suggest you always try to use the correct swift type instead of the foundation types such as NSArray. If you absolutely must use NSArray, you need to cast ResultatRecherche[0] to the correct type before trying to access a property, otherwise it will have the type of AnyObject.
