My application crashes while trying to present a view controller. It only seems to happen in the device but not in the simulator.
Also do I need to disable the breakpoints before archiving the build for TestFlight?
Here is the crash log:

Could some one please look into the logs and point me in the right direction?
following is the code which crash log points to
let lastLaunch = Foundation.UserDefaults.standard.double(forKey: "lastLaunch")
let lastLaunchDate = Date(timeIntervalSince1970: lastLaunch)
let lastLaunchIsToday = Calendar.current.isDateInToday(lastLaunchDate)
if !lastLaunchIsToday {
// Show the GIF
let zayedVC: ZayedVideoViewController = self.storyboard?.instantiateViewController(withIdentifier: "ZayedVC") as! ZayedVideoViewController
zayedVC.providesPresentationContextTransitionStyle = true
zayedVC.definesPresentationContext = true
zayedVC.isModalInPopover = true
zayedVC.modalPresentationStyle = .overFullScreen
self.navigationController?.present(zayedVC, animated: false, completion: nil)
}
Foundation.UserDefaults.standard.set(Date().timeIntervalSince1970, forKey: "lastLaunch")
Alright,
I have managed to solve the problem,the issue i had is the broken outlet connection.
I have removed it from the storyboard and it worked fine

I've got crash logs for my app from App Store. I'm not able to reproduce the crash and having a hard time deciphering it.

Following is the code snippet where the program crashes. The crash happens at the self.view.layoutIfNeeded().
func initialSetupForScreen(){
let screenHeight = UIScreen.main.bounds.height
let statusBarHeight = UIApplication.shared.statusBarFrame.height
fullyOpenSheetTop = -(screenHeight - (statusBarHeight * 2))
partiallyOpenSheetTop = -((screenHeight * 0.50) - titleBarHeight)
closedSheetTop = -titleBarHeight
notVisibleSheetTop = 40 //(+40 for iphone X)
fullyOrPartiallyThreshold = (fullyOpenSheetTop + partiallyOpenSheetTop)/2
partiallyOrClosedThreshold = (partiallyOpenSheetTop + closedSheetTop)/2
// set primary & secondary sheet height //(+40 for iphone X) (-40 fixed for iphone X)
primarySheetViewHeightConstraint.constant = -fullyOpenSheetTop
secondarySheetViewHeightConstraint.constant = -fullyOpenSheetTop
// primary sheet is set to fully open state
primarySheetViewTopConstraint.constant = fullyOpenSheetTop
primarySheetCurrentState = .fullyOpen
// secondary sheet is set to not visible state
secondarySheetViewTopConstraint.constant = notVisibleSheetTop
secondarySheetCurrentState = .notVisible
// settings View move it out of screen
settingsViewTopConstraint.constant = notVisibleSheetTop
primarySheetController.configurePrimarySheetContentView()
self.view.layoutIfNeeded()
}
Earlier, I was calling this function inside my viewDidLoad. I thought it was too early to call layoutIfNeeded inside viewDidLoad. So I moved the function to viewWillAppear. However, the crashes still seem to be happening . What am I missing/overseeing?
The crash is happening across very few devices and I'm not able to reproduce it.
When trying to launch my Application not using Xcode, the App crashes upon opening a specific ViewController. I've checked the Device Logs but I can't figure out what exactly caused the problem.

I get a strange crash when presenting a modal view controller on iOS 7, it only happens on iPhone 5C I haven't been able to repro on the iPhone 5 or 5s. I've attached the crash log below, as well as the code that presents the view controller. I used the presenting view controller as the transitioning delegate to have a custom fade in effect. Please let me know if you need any more information about this.
Code to present:
PresentedViewController *vc = [[PresentedViewController alloc] init];
vc.transitioningDelegate = self;
vc.modalPresentationStyle = UIModalPresentationCustom;
[self presentViewController:vc animated:YES completion:nil];

I am not able to reproduce this crash but received this kind of crashes multiple times from production build. In my app tab bar is loaded from storyboard only and tab bar is always hidden all the time.
Does it's main cause is low memory? Any guess, how to solve or reproduce this kind of problems

Maybe set a break point at that code, and check if your string length is larger than or equal to the range.
