Make a console based app in mac in objective-c to read / write / split files

Hello I am an OS X system developer. I can help you with the project. Can you give some more details? I worked with XML parsing, and text processing using Objective-C

Hello, I have a good background coding in Objective-C for OS X. Please give me more details about the operations you need this code to do on files. I can test the code on OS X Yosemite with Xcode 6.x (latest version). Thanks and let me know if you are interested to work with me, Paul

I have experience in this area. I made Mac OS applications with ObjectiveC. Please describe your task in more details. Give me examples of files.
