I'm studying iOS crash analysis. Now, I need to import crashlog files into LLDB. As WWDC18 Session 414 said, I now have a copy of myApp, dSYM, ***.crash. Run the following command in a folder that I created:$ lldb(lldb) command script import lldb.macosx.crashlog(lldb) crashlog /xxxx.crashHowever, the stack trace file is not available and there is only a lot of error like:error: unable to locate any executables from the crash logDid I use it wrong? What is the correct stepts?Thanks in advance. For any question please just let me know.
