allWithSuccess failing with reason [LBModel setId:]: unrecognized selector sent to instance

[sw8fbar]

Hi I am using swift with the loopback-sdk-ios. The code is as follows

`import Foundation

class Organization : LBPersistedModel {

var    name: String!
var    state: String!
var    country: String!
var    logo: String!
var    contentType: String!
var    mapCenter: GeoCode?

}

class OrgRepositories : LBPersistedModelRepository {

override init!(className name: String!) {
    super.init(className: "Orgs")
}

override init(){
    super.init(className: "Orgs")

}

class func repository() -> OrgRepositories {
    return OrgRepositories()
}

}

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

static let adapter = LBRESTAdapter(URL: NSURL(string: "http://localhost:3000/api"))
static let orgRepo = adapter.repositoryWithClass(OrgRepositories) as! OrgRepositories

}

class AppSetupViewController: UIViewController {

 func getOrgList(){

    AppDelegate.orgRepo.allWithSuccess({ (fetchedOrg: [AnyObject]!) -> Void in
            print("fetchedOrg \(fetchedOrg)")
            let orgs = fetchedOrg as! [Organization]
            print("org list \(orgs)")

        }, failure: { (error: NSError!) -> Void in
            NSLog(error.description)
    })

}

} `

The following is the error. Could you please help with identifying the reason?

Figured it out. Need to set the modelClass for the Repository

@sw8fbar hi, I am having the exactly problem as you mentioned in this issue, can you provide some pointers on what you mean in your comment exactly? Thanks a lot!

[sw8fbar]

hi Kevin, Try this in your repository definition, replace Organization with your Swift Model Name

override init!(className name: String!) {
    super.init(className: "Orgs")
    self.modelClass = Organization.self
}
override init(){
    super.init(className: "Orgs")
    self.modelClass = Organization.self   
}

Instead of specifying the modelClass, you can also import CoreData in your model repository. That should fix the problem too.

Thanks a lot @sw8fbar ! That really fix the problem!
