Have you ever developed an iOS mobile application in Objective C or in Swift? Then I guess at some point you have "googled" convert HEX or RGB colors to UIColor or UIColor picker. Same happened with me. So while I was developing "Go Back" - an application written in Swift where you can store your location and find your way back there at any time - I had to use a color converter or a color picker for UI Color.
UIcolor.xyz is a tiny Angular app, where you can either convert HEX & RGB(A) colors or you can use the color picker and it will generate the code you need to copy & paste to your iOS application.
# It's obvious that it's not that easy to convert colors without a converter HEX: #bd3e3e RGB: R-189 G-62 B-62 Objective C: [UIColor colorWithRed:0.74 green:0.24 blue:0.24 alpha:1.0]; Swift: UIColor(red:0.74, green:0.24, blue:0.24, alpha:1.0)
I guess after the example above it will all make sense right? The application is hosted on GitHub Pages and it is of course open-sourced so feel free to get involved! It's free and easy to use. You can now head to http://www.uicolor.xyz/ and give it a try.
