Stack canaries in Swift vs. Objective-C

[nitram2342]

checksec.rs seems to be the only checksec tool that also checks Mach-O files. I stumbled upon this tool due to this check. However, the stack canaries check looks up symbols related to Objective-C code, which is also suggested in guides such as the Mobile Security Testing Guide. According to what I read on the Internet, Swift code has a per default built-in stack protection. For Swift libraries, the stack canary is shown to be disabled. It is misleading, but I don't know how to implement a better check. Maybe the tool could call them ObjC Stack canaries to be a bit more specific. Maybe the tool could add a heuristic check, if the library is Swift-based, Objective-C-based or mixed. Maybe it is more clear than.
