我正在使用swiftUI和swift开发一个macOS虚拟相机插件的应用程序。它也有C++和目标C库。当我们通过缩放使用该插件时，随机发生崩溃。
这次死机的主要原因是什么？我对代码做了几次修改，但还是没有消除这次死机。有人能解释一下吗？
崩溃报告如下所示。

0x20处的无效地址几乎总是意味着指向对象或结构的NULL指针被取消引用，并且访问了偏移量为32字节的成员。
崩溃发生在对[object retain]的调用中的Stream.sendInformation（information：with：）中。通常在objc中保留一个nil指针是安全的，所以我可能会仔细观察swift是否在这里对空性做出任何保证，以避免这种情况。我不太使用swift，我不能确定objc nil安全性是源于objc_retain还是更可能源于objc_msg_send。无论如何，在调试器中运行这个东西可能会对正在发生的事情有所帮助。您也可能会在构建中处理任何关于忽略空性要求的警告，或者可能您在自己的接口中设置了一些可空性，但未能满足要求。
