thanks!

update: here how initialize it:

import foundation import uikit  class zmanimviewcontroller: yidcontroller { override func viewdidload() {     let controller = zmanimcontroller()  } } 

as allocating zmanimcontroller instance local variable inside viewdidload released function returns.

you should allocate object instance object property of yidcontroller, way have same lifetime object instance.
