error: 'AsyncImageView' is ambiguous for type lookup in this context

[fidergo-stephane-gourichon]

When using AsyncImageView 1.5.1 and Spring https://github.com/MengTo/Spring, both as pods in a Swift project, the following compile-time error occurs:

error: 'AsyncImageView' is ambiguous for type lookup in this context
    @IBOutlet weak var myvariable:AsyncImageView!
                                  ^~~~~~~~~~~~~~
AsyncImageView.AsyncImageView:1:29: note: found this candidate
@objc(AsyncImageView) class AsyncImageView : UIImageView
                            ^
Spring.AsyncImageView:1:13: note: found this candidate
@objc class AsyncImageView : UIImageView

The traditional tool to fix such problems is separate namespaces, but there are no namespaces.

Based on similar problem Haneke/HanekeSwift#147 and instructions in https://github.com/raywenderlich/swift-style-guide#class-prefixes or http://stackoverflow.com/questions/24214863/swift-class-prefix-needed, I tried to prefix the type specification like this:

@IBOutlet weak var myvariable:AsyncImageView.AsyncImageView!

but it produced the exact same error message.

How to use both pods in a project ?
