When using HTML select element, UIWebView presents a native UIPopoverController as dropdown list on iPad (iPhone uses UIPickerView which works fine).
On iOS11 this appears to be completely broken:
Clicking outside dropdown to dismiss without selecting an option results in popover being closed and immediately re-presented, occasionally empty
When more than one drop down on the page, drop down for new list contains elements from previous list
When selecting second drop down, first one re-opens
Occassionally drop down appears in top left corner (presumably lost it's source view)
Above steps very occasionally result in the following crash:

I created a sample application with one line of code which demonstrates the issue:
https://github.com/AshRobinson/BrokenUIWebView
http://gph.is/2xmHFWs
Does anyone have a workaround for such issue? Migrating to WKWebview is not an option for us at this stage.
Is there any way to force iPad to use UIPickerView for dropdowns as per iPhone temporarily?
I have investigated suggestions in other stack overflow posts with no luck, for example:
ios 11 Beta 5 select drop-down list issue
We ran into the same bug. Apple's documentation says that any app iOS 8+ should be using WKWebView. Once we switched to WKWebView, we are no longer seeing this issue.
I ran into this issue, with a WKWebView that was being added into an UIWindow directly. My problem was that the view didn't have an UIViewcontroller linked to it, so the following lines did the trick:
containerVC = [[UIViewController alloc] init];
[containerVC.view addSubview:myWkWebview];
[window addSubview:containerVC.view];
Instead of adding myWkWebview directly to the window. With this, modal views were added again :-)

I'm a newbie and i'm having this error, i looked up everywhere and i can't find the solution. Any help would be really appreciated!

Check your storyboard: All the IBAction, IBOutlet connected and with their current names? It's actually happens when problem with iboutlets
If you just updated to Swift 4 and have issues running your app on iOS 11 device or simulator, maybe you have the same issue I had with the UIVisualEffectView, and specifically with adding subviews to it.
Apple's documentation says:
Add subviews to the contentView and not to UIVisualEffectView
directly.
Basically, instead of adding subviews directly to the UIVisualEffectView, add them to its .contentView.
Example:
// create UIVisualEffectView
let blackBlur = UIVisualEffectView(effect: UIBlurEffect(style: .dark))
// adding a subview - this worked on iOS 10 - crashes the app on iOS 11
blackBlur.addSubview(someView)
// this works on both iOS 10 and iOS 11
blackBlur.contentView.addSubview(someView)
I hope this helps someone since it took me a while to figure this one out.
If anyone is running into this problem make sure that you
Go to Main.storyboard
RIGHT click on the yellow box icon (view controller) at the top of the phone outline
DELETE the outlet(s) with yellow flags.
What happens in instances like this is you probably named an action, then renamed it. You need to delete the old name and if that was the only issue will start right up in simulator!
NOTE: most of the time this happens because of wrong connection so double check and make sure all outlet connections are correct.
The raising method is setValue:forKey:, which is called after a table view cell was dequeued.
Apparently in the MealTableViewController.
Check your table view cells XIB, there might be an IBOutlet remaining with a wrong name, or maybe a property set with the wrong name.
If you are using Firebase and have this problem when you upload be careful with the key value. The keys should not include '#' or '%' or etc. I just deleted and worked fine.
I have received the below exception backtrace from Apple for an app I had submitted to the app store. I have symbolicated the log but my app's entry has not symbolicated. Any idea what I can do to achieve that? Please see Entry # 14 below which provides more detail. Any help would be much appreciated

Finally solved the problem. I was invoking UIAlertController in my code to present an action sheet with various options. To cater to devices that don't have a camera, I had added a conditional statement to directly present an ImagePicker instead of an action sheet.
iPAD testing was carried out only on the simulator which doesn't have a camera, thus directly invoking the ImagePicker. When he Conditional statement was removed, it tried presenting the Action Sheet through a PopoverPresentationController and crashed - as is evident in statement 2 of the Exception Backtrace.
I subsequently added the following code to fix the oversight:
if let popOver = optionMenu.popoverPresentationController {
popOver.sourceRect = sender.bounds
popOver.sourceView = sender
}
The app runs fine when run on in the iphone simulator, but running it in the ipad retina simulator, I see this crash:
2015-04-15 18:39:13.814 [17308:2881892] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle .app> (loaded)' with name '7bK-jq-Zjz-view-r7i-6Z-zg0''
Not sure what is going on. I do not have nib/xib files with this weird name: '7bK-jq-Zjz-view-r7i-6Z-zg0'
It has been some time since I tried running the ipad simulator. I the meantime some big changes took place (which I am not sure if it resulted in this issue):
1. Renamed the project
2. Upgraded to Swift 1.2 . It does not help reverting the project to before this change, since Sift is already on 1.2.
How would I go about troubleshooting it?
UPDATE
I looked in the storyboard source (as per Kamal's suggestion) and found that '7bK-jq-Zjz' was the ID of a table view controller (this controller is the first tab of a tab bar controller, which in turn is the master view of a split view controller).
The second part of the weird code, 'r7i-6Z-zg0', turned out to be the ID of the table view inside the mentioned table view controller.
I tried two things:
Recreated the split view controller and tab bar controller. Same crash seen with the ipad simulator (still iphone simulator running fine).
Recreated the troublesome table view controller. Still see the same crash, now with a different code/signature since the ID's are now new (for newly created table and table view controller).
Here is the new crash:
2015-04-17 22:10:01.427 [33373:6444860] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle .app> (loaded)' with name '3hh-RB-vwq-view-1d1-Kq-Vzm''
As mentioned iPhone simulators run fine - iPads not. But the iPhone 6 plus sometimes crashes when orientating to landscape mode (i.e. when the split view is not collapsed).

I had this issue starting with iOS 8.3 and finally solved it yesterday. I had hoped the issue would be fixed in iOS 8.4 but it isn't so I'm assuming it isn't considered a bug.
I have a UISplitViewController with 2 UINavigationControllers as the master/detail views. The master view UINavigationController has a UITabBarController. When this was failing, there were 3 UITableViewControllers as the child views for the UITabBarController. The error was exactly what you have: iOS 8.3+ throws an error trying to load the first child view of the tab bar even though the "nib" is definitely there in the storyboard and works fine on iPhone.
The fix for me was to insert a UINavigationController between the UITabBarController and each of the UITableViewController child views. So instead of UITabBarController with "view controller" relationships to 3 UITableViewControllers, the UITabBarController now has "view controllers" relationships to 3 UINavigationControllers and each of those UINavigationControllers have "root view controller" relationships to one of the UITableViewControllers.
This may be too late but I hope it helps someone.
Are you using UISplitController? In this case I solved my issue removing the storyboard segue for master and detail and adding them programmatically
Are you sure you included everything? Make sure to select all the storyboards and add to membership, in side bar, first tab.
I know there is already a question about this, but the answer provided did not solve my problem.
For start, I had 3 three segues pointing to 3 different view controllers and coming from the AMSlideMenuLeftTableViewController class. The first segue and view controller that I created was the view that appeared as the first view (the one that shows when the app loads).
However, since I deleted that first view my app crashes immediately after opening it up.
This is the crash log:

I think the problem is that the app is trying to display the view I deleted as the main view but it isn't there. The fact is that I have not found any reference to that old view I deleted.
If AMSlideMenu catches an exception when trying to create LeftMenu, it then tries to create RightMenu (I don't understand why, but is true).
In my case the left menu firstSegue pointed to a 'wrong view', because it was a simple view controller, not a navigation controller. I changed the view controller to a navigation controller (that points to my original view controller), and that fixed it.
Copy the AMSlideMenuWithoutStoryboard-Prefix.pch file settings to the PCH file from your project.
I am running xcode 5.1.1 and have been trying to learn objective C / iOS development. Right now whenever I try to run my code on the emulator (I do not have an actual device atm) it comes up with a black screen. Code can be found here. Compiling and running gives me the following error:

I have attempted the following things, and so far nothing has worked
1) checked the deployment info, it has the main interface set to main
2) double checked all break points to turn them off and disabled all of them through Debug->Disable Breakpoints
3) Reset Content and Settings on the iOS Simulator.
4) Checked the issue with the LLDB Debugger, however from what I have read the issue is no longer present with the 5.1.1 xcode.
5) checked the local host is still set to 127.0.0.1
Thanks!

I checked out your project. The IBActions for the digits (didgetPressed:) are connected correctly, but the IBOutlets are not connected correctly (the property didgetPressed does not exist).
It will work when you delete the referencing outlets in the storyboard (see picture).
This error message tells us what's wrong:
2014-08-23 10:42:57.429 Calculator[1862:60b] * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key didgetPressed.'
From this we can deduce that, in your storyboard (or xib), you have an object of class XYZViewController. That object once had an outlet named didgetPressed, and you connected that outlet to something else in the storyboard.
Later, you changed something about your project that removed the didgetPressed outlet from that object, but you didn't disconnect the outlet in your storyboard. For example, maybe you changed the outlet name in your Objective-C code to didGetPressed, or maybe you deleted the outlet and changed it to an action, or maybe you changed the object's class (and the prior class had the didgetPressed outlet).
You need to find the XYZViewController object in your storyboard and disconnect the didgetPressed outlet.
The error is self explanatory you can remove that by opening storyboard select XYZViewController goto connection inspector under Utilities panel and remove binding of didgetPressed.
I have check you code just select button with 7 as title and remove it's referencing outlet and run again it will work.
