• Open ichat2json.xcodeproj with Xcode.
• Build it.
• In console you'll find the path of the executable.

Console:

Usage:  /Users/[YOURUSER]/Library/Developer/Xcode/DerivedData/ichat2json-fgxipssxrjlhvrevepwucnmapdzq/Build/Products/Debug/ichat2json path/to/ichat

Copy the path, and use this command in a Terminal to dump it in a file:

EX:

cd /PATH_TO_YOUR_ICHAT_FILE
/Users/[YOURUSER]/Library/Developer/Xcode/DerivedData/ichat2json-fgxipssxrjlhvrevepwucnmapdzq/Build/Products/Debug/ichat2json file.ichat > file.json
