No index path for table cell being reused

Question

This started to happen out of the blue. Any ideas: Code:

CUSTOMCLASSNAME (I have replaced the actual class name as it contains the name of the client.)

Initialis

Answer 1

I found this warning during my viewForHeaderInSection implementation.

This is my solution in Swift 2.x:

let headerView = self.tableView.dequeueReusableCellWithIdentifier("MyCell") as! MyCell
let containerView = UIView(frame:headerView.frame)
headerView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
headerView.myLabel.text = "section title 1"
containerView.addSubview(headerView)
return containerView

This is the Swift 3 version:

let headerView = self.tableView.dequeueReusableCell(withIdentifier: "MyCell") as! MyCell
let containerView = UIView(frame:headerView.frame)
headerView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
headerView.myLabel.text = "section title 1"
containerView.addSubview(headerView)
return containerView
