CloudKit - "Invalid bundle ID for container"

Question

I've just create a project in Xcode 9 beta 6 and add this code:

let privateDB = CKContainer.default().privateCloudDatabase
let greatID = CKRecordID(recordName: "GreatPlace")
let place = CKRecord(recordType: "Place", recordID: greatID)

privateDB.save(place) { (record, error) in
        if error != nil {
            let er = (error as! CKError).errorUserInfo
            print("Error: \n")
            print("CKErrorDescription: \(er["CKErrorDescription"]!)\n")
            print("ContainerID: \(er["ContainerID"]!)\n")
            print("NSDebugDescription: \(er["NSDebugDescription"]!)\n")
            print("NSUnderlyingError: \(er["NSUnderlyingError"]!)\n")
            print("NSLocalizedDescription: \(er["NSLocalizedDescription"]!)\n")
            print("ServerErrorDescription: \(er["ServerErrorDescription"]!)\n")
        }
        if record != nil {
            print("record: \(record!)")
        }
 }

and add this capabilities:

and when I run the code I receive this error message:

What I am doing wrong ?

Answer 1

There was a bug causing some associations to be missed. That bug has been fixed and we automatically fixed the container/app associations that were broken during that time.

If for some reason you still need to redo an association you can either use the Capabilities pane in Xcode or use developer.apple.com -> Certificates, Identifiers & Profiles -> App IDs -> pick the ID -> Edit -> Edit under iCloud -> check the box for the container to disassociate, save, then re-associate.

If you're still stuck please email cloudkit[at]apple.com
