Remove all arranged subviews from UIStackView at once
import UIKit
extension UIStackView {
func removeAllArrangedSubviews() {
let removedSubviews = arrangedSubviews.reduce([]) { (allSubviews, subview) -> [UIView] in
self.removeArrangedSubview(subview)
return allSubviews + [subview]
}
// Deactivate all constraints
NSLayoutConstraint.deactivate(removedSubviews.flatMap({ $0.constraints }))
// Remove the views from self
removedSubviews.forEach({ $0.removeFromSuperview() })
}
}

Just the SnapKit version:

import UIKit
import SnapKit

extension UIStackView {
    
    func removeArrangedSubviews() {
        guard !arrangedSubviews.isEmpty else { return }
        let subviewsToRemove = arrangedSubviews.reduce([]) { allSubviews, subview -> [UIView] in
            self.removeArrangedSubview(subview)
            return allSubviews + [subview]
        }
        subviewsToRemove.forEach { subview in
            subview.snp.removeConstraints()
            subview.removeFromSuperview()
        }
    }
}
