i have looked @ multiple instances of question , have tried many different things , doesn't solve problem.

i have textview constrained 11 lines , becomes scrollable..... want total line count of text content not display size on screen solutions provide me 11 lines true line count +- 30 lines.even if show 5 lines of text returns 11

how can find out line count of text collectivly.

any appreciated

use extension solve problem!

extension string {     func lines(font : uifont, width : cgfloat) -> int {         let constraintrect = cgsize(width: width, height: .greatestfinitemagnitude);         let boundingbox = self.boundingrect(with: constraintrect, options: .useslinefragmentorigin, attributes: [nsfontattributename: font], context: nil);         return int(boundingbox.height/font.lineheight);     } }
