I have two view controllers, LoginViewController and TermsAndPrivacyViewController.
On first view controller, there is a button that has IBAction, which opens TermsAndPrivacyViewController. On TermsAndPrivacyViewController I have web view, that loads url I am passing from LoginViewController. So, this is the code(Login view controller):
@IBAction func tosAction(_ sender: Any)
if let vc = UIStoryboard(name: "Login", bundle: nil).instantiateViewController(withIdentifier: kTOSViewControllerIdentifier) as? TermsAndPrivacyViewController
vc.url = URL(string: kTOSUrl)
self.navigationController?.pushViewController(vc, animated: true)
On TermsAndPrivacyViewController, I have this:
override func viewDidLoad()
super.viewDidLoad()
webView.navigationDelegate = self
if let `url` = url
webView.load(URLRequest(url: url))
webView.allowsBackForwardNavigationGestures = true
So, when I hit a button, app crashes SIGABRT message, and nothing else. Also, I don't get any crash report on Firebase Crashlytics (I have detached an app from a debugger first, and produced a crash).
Now, the strange part :/ ... If I put a breakpoint on a first line of tosAction() method, and go step by step (or just let it continue), everything works normally. No crash???
Am I missing something obvious here? What is the reason of crashing? Also, I tried to put Exception Breakpoint but nothing changes. I only get this:
and a console:
so, kinda no information about crash at all.
EDIT
Ok, now the even more strange part :) I just tried app on different phones.
App crashes on iPhone 6s+, iOS 12.1(16B5059d), but it works normally on iPhone 6, iOS 12.0 (16A366)

maybe you use library or framework that not supported by those device.
you must see the error
did you try this?
when the app crashing, in the console press cmd+F and search exception.
now you can see your error
hope to helpful.

There is nothing in the console. I mean, almost nothing. It says:libc++abi.dylib: terminating with uncaught exception of type NSException

The same code works on other phones. It is very simple and standard code, that always worked. I wonder if it has something with timing...

you sure that you don't delete IBOutlet or Action without disconnecting form ViewController? in the Main.storyboard right click on your ViewController & see you haven't any warning?

Nope. IBOutlet for a button, and its IBAction is there.

so just one things left. I think you use the framework or library that not supported on those device. read you're library's documentation. if it isn't really rum

Maybe you can use segue methods inside your LoginViewController.
@IBAction func tosAction(_ sender: Any)
performSegue(withIdentifier: "GoToWeb", sender: nil)
}
And call prepareForSegue
override func prepare(for segue: UIStoryboardSegue, sender: Any?) improve this answer

And call prepareForSegue
override func prepare(for segue: UIStoryboardSegue, sender: Any?)
if (segue.identifier == "GoToWeb")
let vc = segue.destination as! TermsAndPrivacyViewController
vc.url = "YOUR_URL"
And the code inside TermsAndPrivacyViewController don't change
Edit:
Maybe your not binding well your UIButton, can you verify in the right panel, in the section "Show the connection inspector" if your button is call only once.

To get further information on this type of crashes, open the Breakpoints menu (or press CMD+8), click the plus icon in the bottom left corner and press Exception Breakpoint.... Right click, then edit. Add an action of the type Debugger Command and enter the following:
Reproduce the crash again, this time the console will output a more useful error message.
