In Xcode 14 RC, I'm seeing this in the Console:
[Assert] UINavigationBar decoded as unlocked for UINavigationController, or navigationBar delegate set up incorrectly. Inconsistent configuration may cause problems. navigationController=<MasterNavigationController: 0x135016200>, navigationBar=<UINavigationBar: 0x134f0aec0; frame = (0 20; 0 50); opaque = NO; autoresize = W; layer = <CALayer: 0x600000380be0>> delegate=0x135016200
The above message displays exactly four times immediately at app launch (top of the console) then does not repeat.
MasterNavigationController is the internal class for the app's navigation controller. It is in a Storyboard, with very minimal ObjC code. I am not setting any specific size for the nav bar.
I don't remember seeing this in earlier builds of Xcode, but I can't swear to it that this is new. No assertion actually fires.

We have crash reports as shown below that we haven't yet been able to repro and could use some help deubgging.
My guess is that the app is giving a label or text view an attributed string with an invalid attribute range, but attributed strings are used in many places throughout the app, and I don't know an efficient way to track this down.
I'm posting the stack trace here in hopes that someone more familiar with the internals of the system frameworks mentioned will be able to provide a clue to help narrow where I should look.

I’m having a weird UIKit problem. I have a bunch of views in a UIScrollView and I add a UIContextMenuInteraction to all of them when the view is first loaded. Because they're in a scroll view, only some of the views are initially visible.
The interaction works great for any of the views that are initially on-screen, but if I scroll to reveal new subviews, the context menu interaction has no effect for those.
I used Xcode's View Debugger to confirm that my interaction is still saved in the view's interactions property, even for views that were initially off-screen and were then scrolled in.
What could be happening here?
Hello team i notice that we have a problem in our app that every time the user opens a Textfield the app freezes when the keyboard appears, this behavior was tracked down and it's a UI breaking design on a UIView
[this view it's expandable and is original size is 80]
[when it gets expanded 206.33]
this is the view code I change the colors to easy check the other's views created inside
private lazy var sharedUIPlaybackView: UIView = {
let containerView = UIView().withAutoLayout()
let propertySearchCriteria = PropertySearchCriteriaBuilder(hotelSearchParameters: viewModel.hotelSearchParameters).criteria
var swiftUIView: SwiftUIView<LodgingPlaybackWrapper>! = nil
swiftUIView = SwiftUIView(
LodgingPlaybackWrapper(propertySearchCriteria: propertySearchCriteria,
playbackUpdateNotificationSender: playbackUpdateNotificationSender,
componentHandler: { [weak self] componentId in
self?.componentReady(componentId)
}),
viewDidLayoutSubviewsCallback: { [weak self] in
let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x
let newHeight = swiftUIView.frame.size.height + extraPadding
// if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant {
// self?.sharedUIPlaybackViewHeightConstraint?.constant = 206.33
// }else {
// self?.sharedUIPlaybackViewHeightConstraint?.constant = 80
// }
}
).withAutoLayout().withAccessibilityIdentifier("test")
// sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0)
// sharedUIPlaybackViewHeightConstraint?.isActive = true
containerView.backgroundColor = .blue
swiftUIView.backgroundColor = .red
containerView.addSubview(swiftUIView)
containerView.addConstraints([
swiftUIView.topAnchor.constraint(equalTo: containerView.topAnchor, constant: playbackViewTopConstant),
swiftUIView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: Spacing.spacing4x),
swiftUIView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -Spacing.spacing4x),
swiftUIView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -Spacing.spacing3x),
swiftUIView.heightAnchor.constraint(equalToConstant: 206.33)
])
return containerView
}()
old devs created this function viewDidLayoutSubviewsCallback to connect user interaction on the wrapper and used on UIKit.
this is the part where the math on the function gets weird and messed up the code by crashing the view
viewDidLayoutSubviewsCallback: { [weak self] in
let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x
let newHeight = swiftUIView.frame.size.height + extraPadding
if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant {
self?.sharedUIPlaybackViewHeightConstraint?.constant = newHeight
}
}
).withAutoLayout().withAccessibilityIdentifier("test")
sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0)
sharedUIPlaybackViewHeightConstraint?.isActive = true
I commented this math because is crashing the app and instead of giving a dynamical height I placed as a constant constraint as default height this is how I solved the problem of the UI, but I still need to update the view each time the user clicks and gets call by the method viewDidLayoutSubviewsCallback
what can I do?
I tried to add like a conditional on the method
if newHeight == 80 {
containerView.addConstraints([
swiftUIView.heightAnchor.constraint(equalToConstant: 80.0)
])
containerView.layoutIfNeeded()
}
else {
containerView.addConstraints([
swiftUIView.heightAnchor.constraint(equalToConstant: 206.33)
])
containerView.layoutIfNeeded()
}
like this but it didn't work
[this is how it looks with the constant value of 206.33]
[when it gets open looks good]
Our Apple TV provides UIImages with renderingMode forced to .alwaysTemplate (the images are also configured with "Render As" to "Template image" in the Asset catalog) to UIActions as UIMenuElement when building a UICollectionView UIContextMenuConfiguration.
Problem: these images are not displayed with vibrancy effect by the system.
The issue does not occur with system images (SVG from SF Catalog).
Here is a screenshot showing the issue with custom images ("Trailer" and "Remove from favourites"):
I don't know the underlying implementation of the context menu items image but UIImageView already implements the tintColorDidChange() method and the vibrancy should work if the UIImage is rendered as template.
According to my tests, the vibrancy is correctly applied when using Symbols sets instead of Images sets but I understand that custom images rendered as template should support it as-well, shouldn't they?

Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
Xcode 16.1
iOS 18.1
iPad Air 13-inch (M2)
I have created a completely new Xcode project with Swift and Storyboard.
In Storyboard, I only have a tabBarController with two attached UIViewControllers.
The code from the base project hasn't been changed at all.
I created a UITest with a very simple premise.
let app = XCUIApplication()
override func setupWithError() throws {
continueAfterFailure = false
app.launch()
}
func testTabBarExistence() {
let tabBar = app.tabBars.element(boundBy: 0)
XCTAssertTrue(tabBar.waitForExistence(timeout: 5), "Tab bar should exist")
}
But this test always fails for iPad on iOS 18+, but it will succeed for anything lower (e.g. 17.5)
I have a UITextField in my application, and I want to detect all the keys uniquely to perform all relevant task. However, there is some problem in cleanly identifying some of the keys.
I m not able to identify the backspace key press in the textField(_:shouldChangeCharactersIn:replacementString:) method.
Also I don't know how to detect the Caps Lock key.
I am intending to so this because I want to perform some custom handling for some keys. Can someone help me with what is the way of detecting it under the recommendation from apple. Thanks in advance.
Note: checking for replacementString parameter in shouldChangeCharactersIn method for empty does not help for backspace detection as it overlaps with other cases.
I have a situation where I need to add a UINavigationController as a child view controller within another view controller. When I do this, there is a gap between the bottom of the navigation controller's root view controller and the bottom of the navigation controller's own view. This happens even though I am constraining the navigation controller's view to the edges of its superview, not the safe areas.
I'd really like to eliminate this gap, but nothing I have tried is working.
Based on this TextKit 2 demo project I thought that I could implement syntax highlighting by parsing syntax block tokens (e.g. comments like <!-- --> or /* */) in processEditing and storing their locations, and then actually applying the rendering with NSTextContentStorageDelegate in textContentStorage(_:textParagraphWith:) by checking the location of each paragraph against the store of syntax tokens.
This sort of works except that the rendering is only updated for paragraphs which are changed.
Is there a way to trigger NSTextContentStorage to re-fetch paragraphs in a given range? Or is this a totally misguided approach to the problem?
When I build UITabBarController on (iPad + iOS18), selectedImage on each tabBarItems don't appear. (SwiftUI TabView can change iconImages by state change, so no problem on SwiftUI. But I need to use UITabBarController)
How Could I solve this problem and show the selectedImages?

This is a very strange behavior when pushing vc that I have never seen since I started coding. The pushed ViewController is transparent and only navBarTitle is shown. After the push, you can't control anything unless you go back to the home screen.
STEPS TO REPRODUCE
Long press currency change button below.(currencyWrapper)
Call selectCountry and this bug happens.
SourceCode
let currencyWrapper = UIView()
private func configureCurrencyCard(){
//The strange behavior shows up after long pressing this
currencyWrapper.backgroundColor = .white
currencyWrapper.addTarget(self, action: #selector(changeCurrency))
currencyWrapper.setWidth(currencyChangeIcon.follow(by: 16, x: true))
currencyWrapper.setCenterX(w1/2)
currencyWrapper.setHeight(currencyLabel.follow(by: 12, x: false))
currencyWrapper.roundToCircle(true)
view.addSubview(currencyWrapper)
}
private func selectCountry(country: Country){
let vc = CountryViewController(country: country)
vc.hidesBottomBarWhenPushed = true
navigationController?.pushViewController(vc, animated: true)
}
Hi,
I am getting this crash specific to iOS 18.4. This has happened only on iPad, combined with 18.4. I do not what is causing the crash. I am unable to reproduce the crash. Crash report attached at the bottom of the post.
Thank you.

I have a controller that displays a pdf using UIDocumentInteractionController as the presented view.
When users open it up, it shows fine.
User gets the app backgrounded and session timed out.
After timed out, when the app is brought to foreground, I bring our loginVC by removing the old VC used to show the UIDocumentInteractionController.
All the crashes are happening at this point.
I am not able to reproduce it, but our alert systems show we have crashes happening.
The code that shows the pdf is straight forward
documentViewController = UIDocumentInteractionController()
documentViewController?.delegate = self
documentViewController?.url = url
documentViewController?.presentPreview(animated: true)
and we reset it to nil in delegate documentInteractionControllerDidEndPreview
Based on the crash trace, it seems like the crash happens when our login VC replaces it and only when pdf was displayed. The reason of stressing ONLY because when we have other viewcontroller present and they are removed in a similar way, we do not see any issue.
So we always replace first and then add a new one
childViewController.willMove(toParent: nil)
childViewController.viewIfLoaded?.removeFromSuperview()
childViewController.removeFromParent()
addChild(childViewController)
view.addSubview(childViewController.view)
childViewController.view.frame = view.bounds
childViewController.didMove(toParent: self)
Raised a ticket with Apple, but I haven't heard back, and it's been a month. Posting here in case anyone experiences the same and has any solutions. I saw some related posts, and solution was to remove the pdf the moment the app goes to the background, but I am trying to find some alternate solution if possible.

Hi everyone, i'im having troubles using Annotation on a Map View. I have a a core data model called Location that conforms to NSManagedObject from CoreData and MKAnnotation form MapKit, and i'm trying to add an array of Location to a MKMview instance in a UIViewController class, by doing somethhing like this: mapView.addAnnotation(locations), but xcode compliants with a strange error which says Argument type '[Location]' does not conform to expected type 'MKAnnotation'. it's strange to me because my Location class conforms to MKAnnotation protocol and i implemented the protocol's methods (coordinate, title, subtitle).
Please can anyone help me how to fix this issues. Thank you all
