error: process exited with status -1 (attach failed (attached to process, but could not pause execution; attach failed))
State = 10

ERROR: Could not launch process.
NOTE: There are several reasons why this may happen:
  * Root needs to run "DevToolsSecurity --enable".
  * Older versions of lldb cannot launch more than one process simultaneously.
