ios - 寻找 [BluetoothDevice classicDevice] 无法识别的选择器上的崩溃来源

Question

我发现崩溃实例大幅增加，几个不同的崩溃报告都以相同的致命异常结束:

[BluetoothDevice classicDevice]:无法识别的选择器发送到实例 0x2805a8ba0

这种情况在 iOS 12 中发生过几次，但在 iOS 13 中却出问题了。还有其他人看到这个吗？与iOS 13中新增的蓝牙隐私权限有关吗？我没有其他线索可循，只是试图找到看到此内容的其他人。

导致它的堆栈跟踪与我的应用程序代码中没有任何内容，只有 AppDelegate 的声明行。它是 Foundation、CoreFoundation 和一些称为 BluetoothSettings 的 Apple 框架的混合体。正如您所看到的，我的崩溃日志缺少很多详细信息 - 可能是 dsyms 出了问题，不确定……但它们就在这里。

我在我的应用程序中也看到了这个问题。这是带有符号的堆栈轨道:

到目前为止，这个问题似乎是 iOS 13 独有的(我有 25 份关于此崩溃的报告，全部在 iOS 13 上)。
