I am using a table view in my project, the crashlytics reports are showing a crash in my cellForRowAtIndexPath function on the curly braces exactly which is not helping me to find the bug. I am not being able to reproduce this bug either on my device nor on the simulators. The stack trace is below and the cellForRowAtIndexPath code is attached as an image.

This has nothing todo with the error, but since my reputation is too low, i'll have to write an answere:
Never force-uncast a cell!
...forIndexPath: indexPath) as! ...
This may cause errors and even crashes

I have a Core Data problem - I have two entity's with the second being a one to many relation ship to the first. When trying to load a detailed view controller on the first with the first one's information and a UITableView fo the details of the 2nd, I am hoping this tableView code would allow me to show a blank table if now records are found. Instead I get a crash as indicated above. I have tried to cover the "Event" (the related NSSet) into an array, but I am not sure how to debug this error. Thanks for any pointers!
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "eventCell", for: indexPath)
let eventsOnArray = selectedRecipient?.events.allObjects
let event = eventsOnArray![indexPath.row] as! Event
if selectedRecipient?.events.count != nil {
cell.textLabel?.text = event.event
}
return cell
}

libc++abi.dylib: terminating with uncaught exception of type NSException
Two problems uncovered. one in the data model the secondary entity is called card not events. And two as pointed out by #vadian above should do the load in the viewDidLoad. Thanks
The app sometimes crashes with [NSObject(NSObject) doesNotRecognizeSelector:], the selector being [UIImageView setImage:].
I captured it by setting an exception breakpoint and the crash happens when setting an UIImageView.image in prepareForReuse of a UICollectionViewCell:
class MyCell: UICollectionViewCell {
var coverImageView = UIImageView()
...
override func prepareForReuse() {
super.prepareForReuse()
coverImageView.image = nil
}
}
The prepareForReuse is called then the cell is instantiated:
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = myCollectionView.dequeueReusableCell(withReuseIdentifier: "myReuseID", for: indexPath) as! MyCell
...
}
Why is that happening?
Also I cannot load the quick look data view for the UIImageView so maybe the object has been released?
The error messages in console are:

I think the problem is that you are not calling the designated initializer of UIImageView, therefore its image property is not properly initialized and trying to assign to it crashes the app:
-[NSMallocBlock size]: unrecognized selector sent to instance 0x608000880aa0
The method tries to call the size method on the old image but the old image was set to some random memory address.
To fix it, initialize UIImageView properly using the designated initializer:
var coverImageView = UIImageView(image: nil)
This question already has answers here:
"Unrecognized selector sent to instance" error

Closed 7 years ago.
I've run into an annoying issue when trying to segue to a Pages View Controller from my initial UIViewController. My initial UIViewController, among other things, includes a UITextField. Everytime I attempt to segue out of my initial UIViewController after I've used the UITextField at all, the app crashes with the error below. If I don't interact with the UITextField I seem to be able to use segues at will. From reading other posts I'm lead to believe there are some resources being used by the UITextField that I'm not properly releasing, but after trying numerous longshot attempts at fixing it, I'm left out of ideas/knowledge.

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)
Last bit of code before the segue is called:
#IBAction func learnButtonPressed(sender: UIButton) {
view.endEditing(true)
textInputFieldOutlet.resignFirstResponder()
textFieldShouldEndEditing(textInputFieldOutlet)
performSegueWithIdentifier("LearnPagesSegue", sender: nil)
}
I can't find any methods or objects in my code named -textFieldCancel, and the only other UITextField I can think of would be in the included CardIO library, which doesn't seem to be the suspect.
I'm using Xcode 6.3.2 and the latest version of Swift.
Any help or gentle nudges are appreciated.
Thanks!
Check that there isn't an old connection from your button by right clicking on it in the storyboard and examining the outlets in the list. You may have an old connection that you forgot to eliminate.
Is this a problem that is caused by adding map pins/annotations and releasing them too often?
My thread trace shows: 0 obj_msgSend and 1 MKMapRectIntersectsRect which lets me know that adding a pin to the map is the problem.
I have a table view which leads to a detail view which contains the map. It seems that the error is only thrown when I quickly tap into and out of my detail view(from segues of different cells). I tried changing the way I released my annotation and removed it from the map view but to no avail.

Having meticulously followed the examples and instructions in the Table View Programming Guide for iOS about the proper order in which UITableView delegate and data source methods are called, I thought I had a good idea of how to implement the “handshake” shown in Figure 7-1 and the list that follows, but apparently not.
Here's the code I'm using…
- (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath {
NSLog(#"Removing %# row %d.", [dataModel objectAtIndex: indexPath.row], indexPath.row);
[tableView deleteRowsAtIndexPaths: [NSArray arrayWithObjects: indexPath, nil] withRowAnimation: UITableViewRowAnimationFade];
[dataModel removeObjectAtIndex: indexPath.row];
}
tableView is the UITableView
dataModel is an NSArray instance that holds the objects represented by the UITableViewCells from the tableView.
…and the error I'm getting…
