This crash is reported by a crash reporting tool, It only happens on iOS7 and I am not able to reproduce.
It seems like something calls scrollView:contentSizeForZoomScale:withProposedSize, the cell contains 2 buttons that resize depending on the data passed to it (no scrollViews, and nowhere a delegate for any UIScrollView is getting set).
Any thoughts on what causes the scrollView delegate method to get called on the cell?

EDIT:
Implemented that method, and it looks like it's being called by:
<UITableViewCellScrollView: 0x78e39ee0; frame = (0 0; 320 44); autoresize = W+H; gestureRecognizers = <NSArray: 0x78eafc10>; layer = <CALayer: 0x78e354a0>; contentOffset: {0, 0}>
On iOS7 apple made changes to the view hierarchy of a UITableViewCell.
In iOS 7 the contntView is embedded in a UIScrollView, and the scrollView on some situations (I haven't figured out when) calls that method on the cell.
The fix was to implement the following method and return the poposedSize. This fix is only needed on iOS7. The viewHierarchy on iOS8+ has been changed to the way it was on iOS6. (No more UIScrollView is used in a tableViewCell hierarchy)
- (CGSize)scrollView:(id)arg1 contentSizeForZoomScale:(float)arg2 withProposedSize:(CGSize)arg3 {
return arg3;
}

I have been getting the below error and none of the existing Stack Overflow answers helped. I am poor at finding the exact location where error is formed by looking console results.
This is the error I get when I run in older devices (works fine in newer devices). What things can I try to determine the problem?

I had the same issue (using Xcode11 and running iOS 10.3.1).
Unchecking Content Layout Guides from the Scroll View worked for me.
image
Thanks to #Luke's answer I've found the exact reason of the problem: it is caused by constraints between any item and scroll view's Content Layout Guide.
So to find where the problem one needs to:
check the log to find out which view controller participates in the problem. According to the log shown by #Jaseel.Dev it is "Alexis_Hospital"
In that view controller in Interface Builder check all scroll views and their Content Layout Guides or Frame Layout Guides
There 2 ways to fix:
a) click on the scroll view, there Uncheck [ ] Content Layout Guides and check them again (Interface Builder will reassign the "layout guide" edges to "superview")
b) click on the Content Autolayout Guide and check if there any constraints pointing to them. Get rid of those constraints.
The main idea is to remove these constrains, which would crash on iOS 10 and earlier.
Please check following things in your source code:
Check if your Xib or Storyboard file has warnings with IBOutlet or
IBAction connection.
It looks like the error should be in your Xib or Storyboard since the error log backtraces shows error at UINibDecoder.
UILayoutGuide is available from iOS 9.0+, so check your app's deployment target which should be iOS 9 or above.
Also you have mentioned that you are seeing this issue only in older devices which may run with less than iOS 9.
Uncheck "Use Safe Area Layout Guides" option in the File Inspector in Xcode.
Finally check your previous working version of source code and compare the recent changes with error codebase to determine the reason for crash.

Does anybody know what could be the cause of this kind of crashes?
Thanks.
When performing programatically performing a segue, the segue does work and the intended storyboard opens, but terminates immediately afterwards. The view controller/storyboard does work and shouldn't have any errors in the code as I've tested it individually, so I'm not entirely sure as to why it terminates. Any help would be appreciated.

The issue (discovered in the comments above) was that there was an action in the storyboard that was no longer hooked up to an action in code.
If anyone else in the future has a similar problem, look through the outlets menu for an outlet or action with the name provided in the console output. In this case, the action was named NameInputEditingDidEnd.
To expand on Nathan's answer, instead of randomly looking around, just cmd+shift+f the name of the outlet, in this case NameInputEditingDidEnd, and xcode will output the storyboard with the dangling outlet for you and center you to it.
In viewDidLoad I have only 2 strings:
MKMapView *mapViewMy = [[MKMapView alloc]init];
[self.view addSubview:mapViewMy];
And the app crashed on "[self.view addSubview:mapViewMy]". I use iOS7. It crashes both on devices and simulators. When I use simulator I have crash report:

I checked, both mapViewMy and self.view are not nil.
Its seems like in our viewDidLoad your object is miss referencing
Make sure you have added Framework of MapKit
Import Map Kit & Delegate in your .h file
Try this code :
MKMapView *mapViewMy = [[MKMapView alloc] initWithFrame:self.view.bounds];
mapViewMy.delegate=self;
[self.view addSubview:mapViewMy];
You need to add map kit delegates methods. :)
in .h file
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
//import MKMapkit framwork
#interface mapSampleViewController : UIViewController {
<MKMapViewDelegate>//mapview delegate
{
MKMapView *mapView;
}
in .m file
add this code in viewdidload
mapView= [[MKMapView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
mapView.delegate = self;
[self.view addSubview:mapView];
I have updated my app to IOS7 and now I have very strange issue.
When I start app it start to do what it suppose to do and after 3-5 minutes app stops to work. But not completely. It stops to send notifications, track location etc.
And if I try to make some action I get this in console:

Any idea what is this?
App works fine in IOS6.
Create an exception breakpoint in Xcode that stops on all exceptions. Then the debugger will stop when that exception is raised. It looks like it is in
[UINib instantiateWithOwner:options:]
But I can't tell if you are calling that or the system.
See here for a related issue:
Terminating app due to uncaught exception 'NSUnknownKeyException'
I must test this on real phone just to be sure.
I have a piece of code that refreshes some labels in the view every X seconds.
It works fine until IOS7. On IOS7 app crashes after 3 minutes and I get the error from the question.
Every time I refresh labels in the view I was opened a new connection to sqlite to get data.
In IOS7 I get error so I made one instance of data access class and init it only in viewDidLoad() and now it works fine.
If after test I confirm that I am right I will definitely make singleton pattern of my data access class.
