ios - Firebase SDK for iOS 更新导致 Zombie Object 崩溃

问题描述

我们将 Firebase iOS SDK 版本从 6.32.2 更新到了最新版本：7.10.0

使用的库（及其依赖项）：

设置是手动完成的（基于提供的 README.md）并且没有使用依赖管理器。最新版本没有任何问题，但新版本在方案的诊断设置中启用“僵尸对象”时会导致以下崩溃：

试用应用程序时的随机 Xcode 控制台输出：

objc[73435]: Class _NSZombie_NSURLRequest is implemented in both ?? (0x7fb7c65124b0) and ?? (0x7fb7c6212760). One of the two will be used. Which one is undefined.

这可能是什么原因造成的？我没有在 GitHub 中创建错误票，因为这似乎是一个设置问题。
