I'm working on a new project that requires loads of empty data set, so might as well rewrite this lib in Swift. A rewrite has been long due.

Just putting the PR out there for visibility for now. I need eyes on this code, specially for reviewing and applying good practices. I'm looking to simplify the code as much as possible, while still being easy to read and inviting for contributions.

This rewrite won't be exactly how it was proposed on #174.
This won't be:

  • An Objc-C compatible version
  • Fully backwards compatible. Most APIs will be, but not entirely.
  • Fully featured like the original project. Instead, it will be simple and extendable.

Initial prototype is looking crisp.

In my opinion this Swift rewrite is almost ready, with some slight changes, but in a separate project, maybe DZNEmptyDataSet-Swift as it does not have full feature parity with DZNEmptyDataSet, like you noted. I think this could totally be released as a simple Swift Package, and people could start using it 😄

Does not conform to protocol EmptyDataSetSource, needs to implement:

imageTintColor(forEmptyDataSet scrollView: UIScrollView)


protocol EmptyDataSetProtocol {
func swizzle() -> Bool
func isEmpty() -> Bool

This method isEmpty() doesn't seem to be used anywhere, only implemented. Is this intended?


public var isEmptyDataSetVisible: Bool {
// guard let view = emptyDataSetView else { return false }
// return !view.isHidden

If this is the default implementation (returning true) then this should be removed
