Attach to process
AppCode provides a way to attach the debugger to local processes as well as to the processes on remote iOS devices.
First off, if you want to debug a program that can be started from AppCode, the best way to do so is to start a local debugging session.
Attach to a local process
Press ⌃ ⌥ F5 or choosefrom the main menu.
AppCode will show the list of the running local processes. Select the process to attach to.
If necessary, narrow down the list of processes by typing the first letters of its name or PID.
Note that in case the process you have attached to does not provide debug information, breakpoints will be unavailable and stepping will be performed in the disassembly view.
Detach from a process
The procedure to detach from a remote process is the same as for stopping a local debug session, however, the effect is different. When you detach, the debugging session closes but the process continues to run.
Click the Stop button on the main toolbar on in the Debug tool window.
Alternatively, click Stop on the main toolbar or press ⌃ F2, then select the session to be closed.
