Create a UITableView Footer / Header With a Dynamic Height (using AutoLayout). All snippets must be implemented by a UIVIewController subclass

createFooter.m

- (void)viewDidLoad {
  [super viewDidLoad];
    .
    .
    .
  FooterView *footerView = [[FooterView alloc]init...];
  footerView.delegate = self;
  CGFloat footerHeight = 200.0;
  footerView.frame = CGRectMake(0, 0, self.view.frame.size.width, footerHeight); //dummy, but mandatory
  self.tableView.tableFooterView = footerView;
}

FooterFix.m

-(void)viewDidLayoutSubviews{
    [super viewDidLayoutSubviews];
    
    if (!self.tableView.tableFooterView){
        return;
    }
    UIView *footerView = (UIView /*you can replace with you concrete type*/ *)self.tableView.tableFooterView;
    CGFloat width = self.tableView.bounds.size.width;
    CGSize size = [footerView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    if (footerView.frame.size.height != size.height) {
        footerView.frame = CGRectMake(0, 0, width, size.height);
        self.tableView.tableFooterView = footerView;
    }

}

FooterFix.swift

override func viewDidLayoutSubviews() {
  super.viewDidLayoutSubviews()
  
  guard let footerView = self.tableView.tableFooterView else {
    return
  }
  let footerView = self.tableView.tableFooterView
  let width = self.tableView.bounds.size.width
  let size = footerView.systemLayoutSizeFitting(CGSize(width: width, height: UIView.layoutFittingCompressedSize.height))
  if footerView.frame.size.height != size.height { //avoid hang
    footerView.frame.size.height = size.height
    self.tableView.tableFooterView = footerView
  }
