Some handy methods for view debugging in iOS.

SuperviewsAndSubviews.swift

extension UIView {
    
    func firstSuperview<T: UIView>(ofType type: T.Type) -> T? {
        guard let superview = superview else {
            return nil
        }
        if let superViewAsT = superview as? T {
            return superViewAsT
        }
        return superview.firstSuperview(ofType: type)
    }
    
    func firstSubview<T: UIView>(ofType type: T.Type) -> T? {
        guard subviews.isEmpty == false else {
            return nil
        }
        if let firstOfType = subviews.first(where: { $0 is T }) as? T {
            return firstOfType
        }
        for view in subviews {
            if let subviewOfType = view.firstSubview(ofType: type) {
                return subviewOfType
            }
        }
        return nil
    }
    
    func allSubviews<T: UIView>(ofType type: T.Type, isRecursive: Bool = true) -> [T] {
        var tViews = subviews.compactMap { $0 as? T }
        if isRecursive {
            subviews.forEach { tViews += $0.allSubviews(ofType: type) }
        }
        return tViews
    }
    
    func forEachSubview(isRecursive: Bool, doBlock: (UIView)->()) {
        subviews.forEach { (subview) in
            doBlock(subview)
            if isRecursive {
                subview.forEachSubview(isRecursive: isRecursive, doBlock: doBlock)
            }
        }
    }
    
}
