I'm tired of Chisel crapping the bed. Time to roll a native solution.

ViewHierarchy.swift

extension UIApplication {
    
    static func printAppVCHierarchy() {
        shared.printViewControllerHierarchy()
    }
    
    func printViewControllerHierarchy() {
        guard let rootVC = keyWindow?.rootViewController else {
            print("Print failed. No root view controller found.")
            return
        }
        rootVC.printViewControllerHierarchy()
    }
    
}

private extension UIViewController {
    
    func printViewControllerHierarchy() {
        let strings = vcHierarchyStrings().joined(separator: "\n")
        print("\nAPPLICATION VIEW CONTROLLER HIERARCHY>>>>>>>>>>>>>>>>>>>>")
        print(strings)
        print("<<<<<<<<<<<<<<<<<<<<APPLICATION VIEW CONTROLLER HIERARCHY\n")
    }
    
    func vcHierarchyStrings(level: Int = 0) -> [String] {
        let level = max(0, level)
        let leadingSpace = repeatElement(" ", count: level * 2).joined()
        var output = [String]()
        output.append("\(leadingSpace)\(self)")
        
        let subVCs: [UIViewController]
        if let navCon = self as? UINavigationController {
            subVCs = navCon.viewControllers
        }
