Swift: Recursively cycle through all subviews to find a specific class and append to an array

Question

Having a devil of a time trying to figure this out. I asked a similar question here: Swift: Get all subviews of a specific type and add to an array

While this works,

Answer 1

My approach with swift 3 and generics!

private func getSubviewsOf(view: UIView) -> [T] {
    var subviews = [T]()

    for subview in view.subviews {
        subviews += getSubviewsOf(view: subview) as [T]

        if let subview = subview as? T {
            subviews.append(subview)
        }
    }

    return subviews
}

To fetch all UILabel's in a view hierarchy, just do this:

let allLabels: [UILabel] = getSubviewsOf(view: theView)
