Need objective C developer to debug an issue

I am looking for an experienced Objective C developer to debug an issue in my project. The project needs to be completed in a few days (3-7 days) and I have existing code that can be reviewed to better understand the issue. This will be a one-time project and will not require any further development work. The developer must be able to identify the issue, debug and provide help with a resolution.

The problem is that the IOS app is doing 3 transaction instead of 1. so needs to debug that issue, the API for payment is eway.com.au which needs to be debgu in the app. I have complete source code available, to share with you and debugg the issue.

I need a serious person who can identify and resolve the issue ASAP.
please include this word in the top of your bid proposal “debugging”. so that I may know you have read the project details.

thank you.
