Write an iOS console application (Objective-C/Swift)

The requirement is to re-write an already existing command line iOS app. There is an iOS console application already on GitHub which is very old and giving compilation errors. We want the same app to be rewritten to make sure it is updated and compiles error free with latest Xcode. You just have to use the existing app as a reference and re-implement the same code in the latest Xcode. It should be a very simple job for an experienced Objective-C/Swift developer. We don't care whether you re-implement it in Swift or Objective-C but we want the same output as the original tool. If you are not experienced with developing console app in Objective-C or Swift, please don't bid. Please note, any bid over 5000 INR will not be entertained. We know it should be fairly within that budget for an experienced iOS developer. The way we would like to work is, once you fairly bid and your bid is within 5000 INR then we will provide you with the GitHub URL for the existing Objective-C code. You'll have to rewrite it and provide us with a proof that you have got a working tool with the same output as the original. The proof can be in the form of a screenshot of the desired output or you have to share your screen for a demo. Then we will immediately award you the project. We will release 50% pay and you share the binary with us for testing. If all looks good then you share the codebase and instructions to compile. We then release the remaining 50% pay. There will be an additional bonus amount if you can deliver it within a day.
