ios - UITableViewCell dynamic height does not work with size classes -

setting estimatedrowheight , rowheight of uitableview makes table view calculate proper height of each cell. works charm until use size classes. seems calculations being done any/any size class , bigger font applied later. result height of cell not calculated , label doesn't fit.

here code:

class viewcontroller: uiviewcontroller, uitableviewdelegate, uitableviewdatasource {      @iboutlet weak var tableview: uitableview!      override func viewdidload() {         super.viewdidload()          self.tableview.estimatedrowheight = 50         self.tableview.rowheight = uitableviewautomaticdimension     }      func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {         return 3     }      func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {         let cell = tableview.dequeuereusablecellwithidentifier("reuse", forindexpath: indexpath) as! mytableviewcell         println("label font size: \(cell.mylabel.font)") // prints (...)font-size: 11.00pt size classes         return cell     } } 

layout looks that:

and usage of size classes is:

now, when open app on iphone looks expected. on ipad cells not resized. in fact resized fit text if font size 11pt instead of 40pt.

the question is: how can force calculations performed after size classes applied?

i tried trick overriding trait collection suggested in: https://stackoverflow.com/a/28514006 didn't work. mean, size class read (regular/regular) font size still 11pt.

you can download simple project github: https://github.com/darecki/tableviewtest

edit: formatting, added github link.

set preferred max width on label in interface builder - > size inspector. solves issue me. make sure number of lines 0.
