ios - swift - libc++abi.dylib : terminating with uncaught exception of type NSException (lldb)

Question

我正在制作一个应用程序，您可以在其中上传照片，然后它获取 downloadURL 并将其保存在数据库中，但在将链接保存到数据库之前我收到错误。

*** 由于未捕获的异常“FIRInvalidArgumentException”而终止应用程序，原因:“不支持的类型:NSURL(在字段链接中找到)”

。。.

libc++abi.dylib:以 NSException 类型的未捕获异常终止(lldb)

线程1:信号SIGABRT

我似乎无法理解为什么。

谢谢

只需添加将 URL 更改为字符串

                                "Link": downloadURL,

到

"Link": downloadURL.absoluteString,
