RTL Support

Hi There
I've been used this amazing library, but i'm having a little issue with direction in Arabic localization, so it's there any method to make start index from right side ?

Thanks

Hi! You can select items manually using the select(index:) method. In your case, you can probably do something like this:

switch UIView.userInterfaceLayoutDirection(for: view.semanticContentAttribute) {
    case .leftToRight:
      pagingViewController.select(index: 0)
    case .rightToLeft:
      pagingViewController.select(index: 3)
}

Let me know if that works for you. I will also look into adding RTL support directly to Parchment 👍

Hi @rechsteiner !
Your answer works for changing selection of menu item in RTL views and for situation which the number of menu items cover entire of the screen, but i have just two tab and need to insert them on screen from right to left (i dont want to fix them to cover entire screen). do you have any idea about this situation ?

Hey guys, I have workaround for this RTL languages. I am using datasource and delegates for PagingViewController and I have an array of titles for all items. when my app uses RTL semantics I reverse the array using something like this

if UIView.appearance().semanticContentAttribute == .forceRightToLeft {
        self.items.reverse()
}

and when the paging controller is added to view controller I set its index to last like this

if UIView.appearance().semanticContentAttribute == .forceRightToLeft {
        self.pagingViewController.select(index: self.items.count - 1, animated: false)
}

I hope this helps other people too

And @rechsteiner thank you so much for your awesome contribution to community

I have second workaround. You can transform PagingViewController, PagingCell and embeded view controllers by:
view.transform = CGAffineTransform(scaleX: -1, y: 1)
