I added an XPC Service to my project and I would like to set breakpoints and inspect variable contents in the debug area in XCode. Breakpoints that I set in the service's code are not recognized (obviously, the debugger is attached to the main apps process. How and I attach the debugger (manually or automatically) to the XPC Service process after my main app launches it?

推荐答案

Debug -> Attach To Process -> By Process Identifier (PID) or Name...

Debug -> Attach To Process -> By Process Identifier (PID) or Name...

输入您的 XPC 服务进程名称.下次 launchd 启动您的 XPC 服务时，Xcode 将附加.

Type in your XPC service process name. The next time launchd starts up your XPC service, Xcode will attach.
