iOS 13, Xcode 11 infinite loop related to the swizzled layoutSubviews()

[sebastienwindal]

We have a custom view and we overrode layoutSubviews() as recommended:

open override func layoutSubviews() {
        super.layoutSubviews()
        // Ensure layout is updated after screen rotation, etc
        self.layoutNode?.view.frame = self.bounds
        // Update frame to match layout
        self.frame.size = self.intrinsicContentSize
    }

and it would appear the app is stuck in some kind of infinite loop, our custom view layoutSubviews () and layout_layoutSubviews() being called forever and blocking the main thread

extension UIView {
    fileprivate static func _swizzle() {
        guard !viewSwizzled else { return }
        replace(#selector(layoutSubviews), of: self, with: #selector(layout_layoutSubviews))
        viewSwizzled = true
    }

    // Swizzled layoutSubviews implementation
    @objc private func layout_layoutSubviews() {
        layout_layoutSubviews()
        _layoutNode?.updateLayout()
    }
}

Same here! Endless loop on iOS 13.1.1 with Layout.
Just on loading the first VC using self.loadLayout() the app is running in endless loop.

@matape I got the same issue on 0.6.36.
Updating to 0.6.38 fixed this issue.

@sebastienwindal @matape can you provide a larger code sample? I'm having trouble reproducing the problem.
