Or add the package in Xcode.

Usage

let page = PageViewController(
    viewControllers: [
        firstViewController,
        secondViewController,
        thirdViewController
    ]
)
// ...
page.transition = { completedPercent, currentIndex, nextIndex in
    guard let currentIndex, let nextIndex else { return }
    print("current index: \(currentIndex)")
    print("current percent: \(completedPercent)")
    print("next index: \(nextIndex)")

    if currentIndex < nextIndex {
        print("\(currentIndex). --\(String(format: "%.3f", completedPercent))--> \(nextIndex).")
    } else {
        print("\(nextIndex). <-\(String(format: "%.3f", completedPercent))-- \(currentIndex).")
    }
}
