JSONDrivenUI

Convert your json into native Views

Simply construct JSONDataView(json: Data) view to setup UI.

OK JSON but how?

  • Specify your view's type (ViewType)
  • properties of it (ViewProperties )
  • values (like text, imageUrl, systemIconName, localImageName) (Values )
  • subviews (for stacks, list & scrollView)

Supported View Types

Image
  • For images we have 3 options. (Order is also like below in case more than 1 set)
    • systemIconName
    • localImageName
    • imageUrl
{
  "type": "Image",
  "values": {
      "systemIconName": "person.crop.circle"
  },
  "properties": {
    "width": 60,
    "height": 60
  }
}
