SegueManager has been moved to a CocoaPod, see the repository.

It is still possible to use it by just copying a single file into your project:

• SegueManager.swift for iOS
• SegueManager.swift for OSX

// We can use Phantom Types to provide strongly typed acces to NSUserDefaults
// Similar to: http://www.objc.io/blog/2014/12/29/functional-snippet-13-phantom-types/


// A key to UserDefaults has a name and phantom type

// Functor type class ported to C#
// Only tested with: Mono C# compiler version 2.4.2.3
//
// Because .NET doesn't support higher kinded generics, we can't exactly port
// the Functor type class.
// However, if we're willing to give up a bit of type safety, we can get the
// IFuctor interface to work.
//
// We only have to add a single type cast, directly after using fmap. E.g:
//     var xs = new List<int>();

// Read type class ported to C#
// Only tested with: Mono C# compiler version 2.4.2.3
//
// Because there are no static interface members, new instances of the
// Dictionary classes have to be created (although they contain no state).
//
// The functions using the read method (like mulStrings) explicitly mention
// `int` in IReadDictionary<int>, but that's just like `x = read "4" :: Int` in
// Haskell.
