user52041: I am trying to create Bitcoin Payment in my IOS project. I'm using swift language. I search this topic in lots of sites, youtube, stack overflow. but i just getting HTTP request related topics. Any one have solution? Ping me... 

user38618: I suggest you to use BitPay's payment API, using Swift's URLRequest. See this answer and this answer for Swift documentation, and this webpage for BitPay API documentation.
Please note that if your app uses Bitcoin payment system your app may not be liked by Apple.

user-1: Core Bitcoin is a library for iOS written in Objective-C.  I have worked with it in Swift using the bridging header.  
I myself have written a few Swift classes, in my experimental/educational wallet, for creating addresses, keys, and transactions, but I wouldn't recommend using it for anything.  Feel free to take a look and see if you find anything interesting, or anything that you could learn from.
