The solution for iOS 10 in Swift with AutoLayout :

Put this code in your custom UITableViewCell

override func layoutSubviews() {
    super.layoutSubviews()

    if #available(iOS 10, *) {
        UIView.animateWithDuration(0.3) { self.contentView.layoutIfNeeded() }
    }
}

In Objective-C:

- (void)layoutSubviews
{
    [super layoutSubviews];

    NSOperatingSystemVersion ios10 = (NSOperatingSystemVersion){10, 0, 0};
    if ([[NSProcessInfo processInfo] isOperatingSystemAtLeastVersion:ios10]) {
        [UIView animateWithDuration:0.3
                         animations:^{
                             [self.contentView layoutIfNeeded];
                         }];
    }
}

This will animate UITableViewCell change height if you have configured your UITableViewDelegate like below :

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return selectedIndexes.contains(indexPath.row) ? Constants.expandedTableViewCellHeight : Constants.collapsedTableViewCellHeight
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    tableView.deselectRowAtIndexPath(indexPath, animated: true)
    tableView.beginUpdates()
    if let index = selectedIndexes.indexOf(indexPath.row) {
        selectedIndexes.removeAtIndex(index)
    } else {
        selectedIndexes.append(indexPath.row)
    }
    tableView.endUpdates()
}
