Hokusai.swift pulled from Cocoapods differs from Hokusai.swift in Github repo

Swift Compiler Error after updating to Swift:
"Argument of '#selector' refers to instance method 'tick' that is not exposed to Objective-C"

Based on my research, adding @objc would expose these instance methods to Objective-C and I see that in the Hokusai.swift file of your latest Hokusai version (0.4.0) on Github you have those @objc attributes. However, when I install the latest Hokusai pod via Cocoapods, I do not see these attributes in the Hokusai file.

Not sure why the Hokusai.swift pulled from Cocoapods differs from the Hokusai.swift here in the repo (the 6 missing @objc attributes seem to be the only difference). For example, in the Hokusai.swift file of the latest master branch, it correctly shows the attribute for example:
@objc func tick(_ displayLink: CADisplayLink)
But in the Hokusai.swift file in my Xcode project, I do not see this @objc attribute, even though I installed the latest Hokusai (0.4.0) (via pod Hokusai in my Podfile).
