Answer 1

将 __ bridge 替换为 __ bridge_transfer

contacts.firstNames = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

参考Apple Docs：

__ bridge 或 CFRelease 在Objective-C和Core Foundation之间传输指针，不会转让所有权。

__ bridge_transfer 或 CFBridgingRelease 将非Objective-C指针移动到Objective-C，并将所有权转移到ARC。 ARC负责放弃对象的所有权。
