Debugger – catch your mistakes!

A typical debugger provides the ability to halt when specific conditions are encountered. It also offers sophisticated functions, such as running a program step by step, breaking or pausing the program for an examination based on breakpoints, and tracking the values of the variables at that state. RubyMotion Version 1.24 and above support debugging using GDB: the GNU project debugger (http://www.gnu.org/software/gdb/).

The RubyMotion debugger provides the following inbuilt debugging facilities:

• It stops the program at a specific line

• It examines the problem when the program has stopped

• It checks the value for the variables at a specific breakpoint

  Note

  The RubyMotion compiler implements the DWARF debugging format's metadata for the Ruby language. This allows external programs, such as the debugger in our case, to retrieve source-level information about the RubyMotion application. The metadata is saved under a .dSYM bundle file at the same level as the .app bundle...
