使用Objective-C时,我们通常使用以下代码来获取详细信息

NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);

在Swift中我尝试了以下内容

var firstName : NSString = ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty).takeUnretainedValue() as NSString

而且由于错误,我无法构建
