Swift Thread 1: EXC_BAD_INSTRUCTION when I try to change a uilabel.text

Question

I know there are a lot of Stack Overflow questions like this out there, but none of the answers I can find work for me. I am using a custom UITableViewCell class called chillerCell. Here is its code:

import UIKit

class chillerCell: UITableViewCell {

    @IBOutlet weak var iconLabel: UILabel!
    @IBOutlet weak var boldLabel: UILabel!
    @IBOutlet weak var italicLabel: UILabel!

    func configureCellWithEvent(event: Event){
        boldLabel.text = "\(event.eventName)"
        italicLabel.text = "\(event.eventDescription)"
    }
}

I get the Thread 1 runtime error on the line boldLabel.text = "\(event.eventName)"

I made my own Event class, and yes, event.eventName and event.eventDescription are of type String and are not Nil.

Edit: I forgot to mention, my boldLabel and italicLabel are not plain text, but attributed text.

Can you give us more detail of the runtime error? Have you checked that your IBOutlet is correctly linked? — Ali Beadle, Jul 08 '15 at 20:19
Yes my storyboard is connected properly. I even disconnected the outlets and reconnected them. — Jonathan Allen Grant, Jul 08 '15 at 20:22
Very strange. Can you check boldLabel in the debugger to ensure it is not nil. If not try changing another property - e.g. BoldLabel.hidden = true. Also try swapping boldLabel and italicLabel to see if it is specific to boldLabel. — Ali Beadle, Jul 09 '15 at 05:06
boldLabel is nil. However, it is definitely connected to the storyboard — Jonathan Allen Grant, Jul 10 '15 at 16:41
OK, but that sounds like the problem. Take a look at [this SO Question](http://stackoverflow.com/questions/6223457/reasons-for-an-iboutlet-to-be-nil) or [this one](http://stackoverflow.com/questions/29321383/iboutlet-is-nil-but-it-is-connected-in-storyboard-swift) to find out why a linked Outlet may still be nil. — Ali Beadle, Jul 10 '15 at 17:11

Try this, it would work if event object having eventName & eventDescription as String:

func configureCellWithEvent(event: Event){
    var attributedString = NSMutableAttributedString(string:"(event.eventName)") and boldLabel.text = attributedString
    boldLabel.text = attributedString
    italicLabel.text = attributedString
}

Can you copy-paste your event object values here? – Dilip Lilaramani Jul 08 '15 at 20:16
And just to double check the IBOutlet connection, just check if this works for you. func configureCellWithEvent(event: Event){ boldLabel.text = "Test Bold Label" italicLabel.text = "Test Italic Label" } – Dilip Lilaramani Jul 08 '15 at 20:18
I just tried the test values and I still got an error – Jonathan Allen Grant Jul 08 '15 at 20:21
So here is the bug then, your IBOutlet connections are broken. Fix that in your storyboard. Go to storyboard and click on label to check or create new IBOutlet using ctrl+drag from UILabel to the class. – Dilip Lilaramani Jul 08 '15 at 20:27
My IBOutlets are fine, I reset them and I still get an error – Jonathan Allen Grant Jul 08 '15 at 20:28
However, both labels are attributed text and not plain text – Jonathan Allen Grant Jul 08 '15 at 20:30
I updated my answer. okkay, then try this. var attributedString = NSMutableAttributedString(string:"\(event.eventName)") and boldLabel.text = attributedString – Dilip Lilaramani Jul 08 '15 at 20:34
It won't let me, so I tried `boldLabel.attributedText` and it still gives me the Thread 1 error – Jonathan Allen Grant Jul 08 '15 at 20:37
