UICollectionView iOS 9 issue on project with RTL languages support

Question

It seems like Apple\'s new feature of auto-flip interface on RTL languages cause problems when using UICollectionView.

I used constraints of type Traili

not pretty though simple math does the trick. (for horizontal collectionview)

- (void)switchSemanticDirection:(UISwitch*)sender {
    //TEST switch the semantic direction between LTR and RTL.
    if (sender.isOn) {
        UIView.appearance.semanticContentAttribute = UISemanticContentAttributeForceLeftToRight;
    } else {
        UIView.appearance.semanticContentAttribute = UISemanticContentAttributeForceRightToLeft;
    }

    [self.myContent removeFromSuperview];
    [self.view addSubview:self.myContent];
    
    //reload your collection view to apply RTL setting programmatically
    [self.list reloadData];
    //position your content into the right offset after flipped RTL
    self.list.contentOffset = CGPointMake(self.list.contentSize.width - self.list.contentOffset.x - self.list.bounds.size.width, 
    self.list.contentOffset.y);
}
