1. the debugger used by Xcode is GDB. GDB is part of the GNU project and can be used on many different platforms. If you want to, you can run it through the command line. GDB has a complete documentation system, although its documentation is difficult to understand and several versions of GDB tutorials are passed on the network.

 

2. multithreading is a programming method that processes multiple execution streams at the same time. It is very difficult to apply it correctly. Generally, the errors produced by multi-threaded programming are very difficult to find. If someone tells you that multi-threaded programming is easy, they are either cheated or trying to sell you something.
