Protocols in Swift are really powerful thanks to be able to be generic and to protocol extensions. But there is some things that drive us nuts. Mainly the usage of generic protocols in collections.
Last week I had to made some changes on the colors of the WorkAngel app. The colors of that app are retrieved through an object called ThemeColor (we have another for the fonts). That object is the concrete implementation of a Theme protocol that defines the names of all the different colors that the app needs.
Yes, the title is not wrong. Apple just released Xcode 6.3 beta that includes multiple huge improvements to Swift 1.2 solving a lot of concerns that we all had. But the cool part is that indirectly Objective-C also has improved.
For now, the Siwft and Objective-C protocols are two diferent things. The biggest differences is that Swift protocols can have structs and enums and can be adopted by value types.
Today I released AMPActivityIndicator. I wrote this little class a year ago and today I made a little clean up and made it available through Cocoapods.
