我正在使用 contactPicker 函数从联系人中挑选并将它们添加到我创建的 tableview 中。但是，当我运行我的应用程序并单击所需的联系人时，我的应用程序崩溃了。问题似乎是 contactPicker(CNContactPickerViewController, didSelect...) 功能。虽然当我查看 swift 文件时没有出现错误。有人可以帮助解决问题吗？
Lookout`Lookout.ViewTwo.contactPicker (Lookout.ViewTwo)(__ObjC.CNContactPickerViewController, didSelectContact : __ObjC.CNContact) -> ():
