I'm trying to add UITableViewController to Today Widget, but every time I drag UITableViewController to Storyboard and run the Widget it crashes with the following error.
I've tried multiple times. I've tried it by using Table View object, but problem persists.
Note: It crashes even before loading viewDidLoad() method.

When you delete the default layout and drag a new table view controller, you need to mark the new view controller as 'Intial View Controller'
Here's the Apple's document which explains how to do it. https://developer.apple.com/library/ios/recipes/xcode_help-IB_storyboard/chapters/SetInitialController.html
In the storyboard, if you are using a custom view controller class made in swift, make sure you check the box 'Inherit Module From Target':
I do not know how I can use the following crash report from crashlytics to narrow down the source of the crash.
All I understand is that it has something to do with CoreFoundation, but what exactly is the crash? And where in my code is it happening?
Is a CAAnimation Delegate? Or perhaps I did not remove and observer from NSNotifications?
Any ideas?

Does anybody know what is going on?
Regards!
An assertion fails in the non-symbolicated lines, probably in your own method. Set a breakpoint at the beginning of your button method and step through until you get the crash.
I found a weird crash issue in my app, and I can't got enough message from the crash report.
Here is the crash report:

Well, it means you tried passing a message (a.k.a calling a method) _isChargeEnabled to an object of class TileLayer, but it is non-existent.
UPDATE
I did a quick google search and turns out _isChargeEnabled is private API of Apple. You could check this and this for more information.
When i am moving the data from tableview cell by one its crashing ..
When my view did loaded my array count is 64
I assign this to number of row return [categorieArray count];
and cell configuration
cell.textLabel.text=[categorieArray objectAtIndex:indexPath.row];

It seems you have an incomplete implementation of your UITableViewDataSource, specifically (it seems) you forgot to implement tableView:cellForRowAtIndexPath, so that when the framework tries and calls it, it fails.
Have a look here for more info.
