swift - CNContactStore 执行失败

Question

我正在研究如何使用联系人框架，但是创建联系人的一些相当简单的代码失败并出现意外结果。这是我的代码:

    let Store = CNContactStore()
    Store.requestAccess(for: .contacts, completionHandler:{ success, error in
        if success {
            let Contact = CNMutableContact()
            Contact.givenName = "Dave"
            Contact.familyName = "Nottage"
            let SaveRequest = CNSaveRequest()
            SaveRequest.add(Contact, toContainerWithIdentifier: nil)
            do {
                try Store.execute(SaveRequest)
                print("Success")
            }
            catch let error as NSError {
                print(error.localizedDescription)
            }
        } else {
            print("No access")
        }
    })

..这是结果:

2019-02-22 10:30:56.050344+1030 ContactsTest[30329:25254955] [default] Unable to load Info.plist exceptions (eGPUOverrides)

The operation couldn’t be completed. (Foundation._GenericObjCError error 0.)

关于可能导致此问题的任何想法？
