Sometimes we might have great ideas and plans, but prototyping proves to be quite challenging. There might be hardships going from paper to the screen - it might not look the same when you try to develop it, and coding can take quite a while. Prototyping should be made easier for both skilled developers and people who are just starting to code.
Sourcery will help you speed up the process of going from the prototype to the code.
Take a picture of your prototype or start from a blank screen, place the components in the right place and get the code in either Swift or Objective-C for iOS. Start developing your own watchOS app and preview it on your Apple Watch.
