Hi, I’m an American Full Stack developer that would be perfect for updating your web service call. I build all my backends with PHP and I use Xcode and Objective C for the front ends. I can do it all when it comes to iOS apps. I can build smooth, well designed front end UI's, fast secure backend API's, and fast efficient databases. I am a true one stop shop for everything you would need to build an iOS app. Plus, I have submitted so many iOS apps that I know Apple's Human Interface Guidelines well enough to make sure you apps get approved the first time. I can guarantee there isn't a better developer for your needs than myself. Thank you for your time, Carey
