Hello! What UIKit API enables you to add a view below the navigation bar and extend the scroll edge effect below it in iOS 26? safeAreaBar is how you do it in SwiftUI but I need to achieve this design in my UIKit app (which has a collection view in a view controller in a navigation controller).
struct ContentView: View {
let segments = ["First", "Second", "Third"]
@State private var selectedSegment = "First"
var body: some View {
NavigationStack {
List(0..<50, id: \.self) { i in
Text("Row \(i + 1)")
}
.safeAreaBar(edge: .top) {
Picker("Segment", selection: $selectedSegment) {
ForEach(segments, id: \.self) {
Text($0)
}
}
.pickerStyle(.segmented)
.padding(.horizontal)
.padding(.bottom, 8)
}
.navigationTitle("Title")
.navigationBarTitleDisplayMode(.inline)
}
}
}
Selecting any option will automatically load the page

I implemented BGContinuedProcessingTask in my app and it seems to be working well for everyone except one user (so far) who has reached out to report nothing happens when they tap the Start Processing button. They have an iPhone 12 Pro Max running iOS 26.1. Restarting iPhone does not fix it.
When they turn off the background processing feature in the app, it works. In that case my code directly calls the function to start processing instead of waiting for it to be invoked in the register block (or submit catch block).
Is this a bug that's possible to occur, maybe device specific? Or have I done something wrong in the implementation?
func startProcessingTapped(_ sender: UIButton) {
if isBackgroundProcessingEnabled {
startBackgroundContinuedProcessing()
} else {
startProcessing(backgroundTask: nil)
}
}
func startBackgroundContinuedProcessing() {
BGTaskScheduler.shared.register(forTaskWithIdentifier: taskIdentifier, using: .main) { @Sendable [weak self] task in
guard self != nil else { return }
startProcessing(backgroundTask: task as? BGContinuedProcessingTask)
}
let request = BGContinuedProcessingTaskRequest(identifier: taskIdentifier, title: title, subtitle: subtitle)
request.strategy = .fail
if BGTaskScheduler.supportedResources.contains(.gpu) {
request.requiredResources = .gpu
}
do {
try BGTaskScheduler.shared.submit(request)
} catch {
startProcessing(backgroundTask: nil)
}
}
func startProcessing(backgroundTask: BGContinuedProcessingTask?) {
// FIXME: Never called for this user when isBackgroundProcessingEnabled is true
}
The documentation for CLGeocoder states
Geocoding requests are rate-limited for each app, so making too many requests in a short period of time may cause some of the requests to fail. (When the maximum rate is exceeded, the geocoder returns an error object with the CLError.Code.network error to the associated completion handler.)
And it provides helpful guidance on how and when to submit geocoding requests.
The documentation for MKReverseGeocodingRequest does not mention requests are rate-limited. Does this mean it is not rate-limited? If it is rate-limited, is it similar to CLGeocoder, what is its behavior?
It is important to understand behavior of the API in order to understand impact on my app’s use case and how users will be affected should I change the implementation. Thanks!
My app is currently using CLGeocoder to get a CLPlacemark, then using placemark.postalAddress with CNPostalAddressFormatter to get an attributed string for the full address, I then enumerate its attributes to pull out specific elements like just the street or state or zip etc.
This is deprecated in iOS 26 with MKReverseGeocodingRequest being the intended replacement. This API returns an MKMapItem which doesn’t provide a CNPostalAddress - you can get a full address as a String but not structured address data that I’m seeing. Am I missing some way to get the postal address? Or is it a non-goal to provide that anymore? Thanks!
If you add a new string in your app (for example String(localized: "contact_support_message", defaultValue: "Please contact support")), then later you change that default value and rebuild, the string catalog updates to match as expected.
But once that string is translated, changing the default value in code and rebuilding does not update the catalog. You seemingly have to go manually change the default value for English in the catalog to match the code (which marks the translation as Needs Review).
Is there a better way? Or is there a way to determine what strings have default values in code that do not match the catalog values to see if any were missed as wording was tweaked over time?
