Where could I find the source code of UIStoryboardSegue.swift

I've been struggling to find examples to implement custom unwind segues that would work with Xcode 10 and Swift 3. I thought looking into the source code would give me a clue.

Unfortunately, I don't even know where to find it (searched my macbook and googling)! Where could I find this file?

EDIT

Solved, see comment & answer below, UIStoryboardSeague.swift is part of UIKit and it is not open source.

Solution

  • The UIStoryboardSegue is part of UIKit. UIKit is not open source.
