I know there are several existing threads on this topic but things keep changing.
The release notes for Xcode 26 beta 3 have the following statements for a couple of resolved issues:
Asset Catalog
Fixed: Unable to set Icon Composer icon as alternate iOS icon (153305178) (FB18025356)
Icon Composer
Fixed: Icon Composer icons back deploy to older versions of iOS, macOS, and watchOS with inconsistent rendering. (152258860)
I had a working solution under beta 1 and beta 2 for both of these. But under beta 3, I am now seeing the new glass icons for my app when running on a simulated iOS 18 device. This is happening for both the main app icon and any alternates. This contradicts the statement that beta 3 fixes this issue.
There is no documentation (that I can find) describing how you are supposed to support old icons for iOS 18 and new glass icons for iOS 26. There is no documentation for how to support alternate glass icons for iOS 26.
What I'm doing at the moment (that worked before beta 3) was to have the normal iOS 18 app icons in the Asset catalog and to have the new glass icons added to the project. The filenames for the glass .icon files have the same name as the app icons in the Assets catalog. This worked under beta 1 and beta 2. And despite the Xcode 26 beta 3 release notes stating that Icon Composer icons no longer back deploy to iOS 18, I'm seeing the opposite. Beta 3 now does the opposite of that statement.
Does anyone have a working solution that supports old iOS 18 app icons and new iOS 26 glass icons using Xcode 26 beta 3?
Note, all of my testing is with simulated iOS devices and I'm running Xcode 26 beta 3 under macOS 15.5. Maybe that's an issue?

Before I file a bug report I wanted to verify that I'm not missing something.
If I setup a view controller in a navigation controller and I add a view with a constraint that lines it up with the view controller's view's layoutMarginsGuide (leadingAnchor or trailingAnchor), in several cases the view will not line up with buttons added in the navigation bar. Under iOS 18 everything lines up as expected.
To demonstrate, create a new iOS project based on Swift/Storyboard. Setup the storyboard to show a UINavigationController with one UIViewController. Then in ViewController.swift (the one embedded in the navigation controller), use the following code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .yellow
title = "Layout Margins"
let leftCancel = UIBarButtonItem(systemItem: .cancel)
navigationItem.leftBarButtonItem = leftCancel
let rightCancel = UIBarButtonItem(systemItem: .cancel)
navigationItem.rightBarButtonItem = rightCancel
let leftView = UIView()
leftView.backgroundColor = .blue
leftView.translatesAutoresizingMaskIntoConstraints = false
self.view.addSubview(leftView)
let rightView = UIView()
rightView.backgroundColor = .red
rightView.translatesAutoresizingMaskIntoConstraints = false
self.view.addSubview(rightView)
NSLayoutConstraint.activate([
leftView.widthAnchor.constraint(equalToConstant: 80),
leftView.heightAnchor.constraint(equalToConstant: 80),
leftView.leadingAnchor.constraint(equalTo: self.view.layoutMarginsGuide.leadingAnchor),
leftView.topAnchor.constraint(equalTo: self.view.layoutMarginsGuide.topAnchor),
rightView.widthAnchor.constraint(equalToConstant: 80),
rightView.heightAnchor.constraint(equalToConstant: 80),
rightView.trailingAnchor.constraint(equalTo: self.view.layoutMarginsGuide.trailingAnchor),
rightView.topAnchor.constraint(equalTo: self.view.layoutMarginsGuide.topAnchor),
])
}
}
This adds a "Cancel" button to both ends of the navigation bar and it adds two little square views lined up with the leading and trailing layout margins.
Here's the results:
iPad running iPadOS 26 beta 3 (note the misalignment). This is really jarring when trying to align another glass button below the cancel button:
iPad running iPadOS 18.5 (aligned just fine):
iPhone in portrait running iOS 26 beta (aligned just fine):
iPhone in landscape running iOS 26 beta (no alignment at all):
iPhone in portrait running iOS 18.5 (aligned just fine):
iPhone in landscape running iOS 18.5 (aligned just fine):
Under iOS 26 on an iPhone (simulator at least) in portrait, the cancel buttons line up with the colored squares. That's good. In landscape, the colored squares have much larger margins as expected (due to the larger safe areas caused by the notch), but the cancel buttons in the navigation bar are not using the same margins. This one is debatable. Under iOS 18 the cancel buttons use larger margins to match the larger safe area. But I can see why under iOS 26 they changed this since the navigation bar doesn't interfere with the notch. But it's inconsistent.
Under iOS 26 on an iPad (simulator at least), it's wrong in any orientation. Despite the lack of any notch or need for a larger safe area, the colored squares are indented just a bit more than the buttons in the navigation bar. I see no reason for this. Under iOS 18 everything lines up as expected.
My real question at this point: Is the mismatched margins on an iPad under iOS 26 between the buttons in the navigation bar and other views added to the view controller a likely bug or am I missing something?
Under macOS 26 and iPadOS, the Help menu in many cases has a menu item for "App Help". This item has the following icon:
I need to use this in my own app. I am unable to find this icon in SF Symbols 7 beta. I've scanned all of the icons under "What's New". I've searched for "help", "light", and "bulb" and this icon does not appear.
Does anyone know if it's even a new SF Symbol? Or does anyone know of a way to use this icon?
I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is:
iOS 18.2 Seed 4
iOS 18.1.1
iOS 17.7.2
An earlier iOS build
I'm not sure
So how to I report this as an iOS 26 beta 1 issue?
I have an iOS app that relies on dynamic text size such that all fonts in the app respect the user's setting of Text Size in the iOS Settings app.
This app also runs on macOS via Mac Catalyst. But until macOS 14 Sonoma, there was no Text Size setting in the macOS Settings app. But even as of Sonoma, the Text Size setting isn't usable by 3rd party apps. And Sequoia doesn't seem to change that.
As a work around, my Mac Catalyst app provides its own Text Size setting. I was able to make it work by providing my own UIApplication subclass and overriding preferredContentSizeCategory. Under macOS 12 to macOS 14, this workaround works just fine and all fonts in the app created with code such as UIFont.preferredFont(forTextStyle:) gives appropriately sized fonts based on the overridden content size category.
However, this workaround stopped working with macOS 15 Sequoia. I've also tried code such as:
self.window.traitOverrides.preferredContentSizeCategory = myCustomSizeCategoryValue
and
self.window.maximumContentSizeCategory = myCustomSizeCategoryValue
self.window.minimumContentSizeCategory = myCustomSizeCategoryValue
in the scene delegate but that made no difference.
Is there any way to get code such as UIFont.preferredFont(forTextStyle:) to return an appropriately sized font based on some app provided content size category in a Mac Catalyst app running under macOS 15?
It sure would be nice if Mac Catalyst apps automatically responded to the macOS Text Size setting under Settings -> Accessibility -> Display -> Text Size just like a native iOS app.
How do you get the cursor to appear programmatically in a custom UITextInput with UITextInteraction?
I have created a custom input field by conforming to UITextInput. It is setup to use UITextInteraction. Everything works very well. If the user taps on the custom field, the cursor (provided by UITextInteraction) appears. The user can type, select, move the cursor, etc.
But I'm stumped trying to get the cursor to appear automatically. With a normal UITextField or UITextView you simply call becomeFirstResponder(). But doing that with my custom UITextInput does not result in the cursor appearing. It only appears if the user taps on the custom field.
I don't know what I'm missing. I don't see any API in UITextInteraction that can be called to say "activate the cursor layer".
Does anyone know what steps are required with a custom UITextInput using UITextInteraction to activate the cursor programmatically without the user needing to tap on the custom field?
Is there any way for a 3rd party macOS app to receive some sort of notification for a change to the Text Size accessibility setting in the Settings app? I have not been able to find any API for this. Several Apple apps (Mail, Notes, and others) update text size based on the setting. I'd like to do the same in my own macOS app.
Background:
I've had an app in the iOS app store for many years. Quite recently I published a Mac version of the app. The Mac version uses the same bundle id and the app is setup in App Store Connect to be the same app. It's my understanding that with this setup, if a user purchases the iOS version, they don't need to pay for the macOS version (or vice versa).
The iOS app started out as a paid app and was later transitioned to a free app with in-app purchases. The new macOS version also supports the same IAPs.
If it makes a difference, the macOS version is built from the iOS code base using Mac Catalyst.
The app uses old StoreKit1 on-device receipt validation.
Issue:
I have a longtime user of the iOS app that has recently installed the macOS version. Their attempt to restore purchases in the macOS version is not resulting in anything being restored. The user originally purchased the old iOS version before it had any in-app purchases.
I log diagnostic info in the app and the user sent me those logs. One of the things I show in the log is information from the receipt. The on-device receipt validation my app does is indicating it is a valid receipt.
The problem is that the receipt states the original version of the app corresponds to the new macOS build. i would expect the receipt to show the version originally purchased years ago on iOS.
Question:
What is supposed to happen in a case like this? When the macOS version of the app requests (and gets) an updated receipt, is the receipt supposed to show the original version as the first macOS version of the app or is it supposed to show the first downloaded version, regardless of OS?
What is the correct logic for restoring purchases if the macOS receipt has no indication of the user ever having used the iOS version for years?
I have a brand new macOS app (built with Mac Catalyst and based on a long existing iOS app) I've submitted to App Store Connect for review. It was rejected due to my Contacts purpose string not being deemed sufficient (despite being the same one the iOS version of the app has been using for years).
Anyway, I made a change to the privacy string and submitted a new build. The new build was rejected and a screenshot showed the About screen with the new build number as well as the privacy string from the original build, not the new build. So I verified that my archive did in fact have an Info.plist with the updated privacy string. So I resubmitted that build again for review and it was rejected again for the same reason. Despite the reviewer claiming, at my request, that a fresh install of the latest build was used.
So I changed the privacy string again and submitted a 3rd new build, again verifying the archive that I was sending through the Xcode Organizer did have the updated (now 3rd) privacy string.
And again the app has been rejected. Despite 2 new builds, the reviewers are still seeing the original privacy string.
Does anyone have any ideas on how to get this resolved?
While working on the Mac Catalyst version of my iOS app, I noticed something interesting. I have a UITextView with the allowsEditingTextAttributes property enabled. When running the app on a Mac, the context menu that appears when right-clicking inside the UITextField includes the menu item "Import from iPhone or iPad". That brings up a menu with 3 options each for my iPhone and iPad that I happen to connected to my Mac recently. There options include "Take Photo", "Scan Documents", and "Add Sketch".
I created a brand new iOS app project and simply added a UITextView to the main view controller. After setting allowsEditingTextAttributes to true, it shows the same behavior.
Some questions:
Is this documented anywhere? I'm guessing this is related to Continuity Camera in some way. But there's no mention of this anywhere that I've seen so far.
How can I prevent this menu from appearing? Nothing related to these menus comes through the canPerformAction(_:withSender:) method. And nothing related to these menus is part of the menu item array sent to the UITextViewDelegate textView(_:editMenuForTextIn:suggestedActions:) method. I need to remove this menu in my app because while I support some text attributes (bold, italic, underline), I do not want to allow pictures to be added.
Does anything else in iOS under Mac Catalyst automatically get similar support? If so, what?
My own iOS app is using AVFoundation to do barcode scanning. Under Mac Catalyst I'm getting an error. Turns out the Apple provided AVCam demo app has the exact same issue.Both the Swift and Objective-C versions of the AVCam demo app fail but the Objective-C version gives a better error so I'll refer to that in the rest of the question.In the AVCamCameraViewController, the configureSession method fails on the line:AVCaptureDeviceInput* videoDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:videoDevice error:&error];The error is:Could not create video device input: Error Domain=AVFoundationErrorDomain Code=-11814 "Cannot Record" UserInfo={NSLocalizedDescription=Cannot Record, NSLocalizedRecoverySuggestion=Try recording again.}It turns out that none of the three attempts to call [AVCaptureDevice defaultDeviceWithDeviceType:... are succeeding.This is the same error I get in my own app though I only attempt to call [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; which is also returning nil.Permission was granted for the app to access the camera.There is nothing related to this issue in the release notes for macOS 10.15. I am running the GM version of 10.15 with Xcode 11.1 on a 2018 15" Macbook Pro.How do we successfully get a video capture device under Mac Catalyst?
In my iPad app running under macOS Catalyst I would like to modify the context menu that appears when you right-click on a UITextViiew but I can't figure out how.I have overridden the buildMenuWithBulder:/buildMenu(with:) method from UIResponder in my view controller and app delegate but none are called when right-clicking on a UITextView.I have been able to disable a couple of the menu options by subclassing UITextView and overriding the canPerformAction:withSender:/canPerformAction(_:withSender:) and targetForAction:withSender:/target(_:withSender:) methods but I can't remove/disable most of the menu.I also overrode the validateCommand:/validate(_:) method in my UITextView subclass and that was only called for a small subset of the menus I wish to remove/disable.The Menus sample app only shows how to modify the app's main menu and how to add a context menu to a view controller but there is no info on how to modify the context menu of a control such as UITextView.Does anyone know how to do this?Specifically I want to remove the Show Fonts and Show Colors menus under Font and I wish to remove the whole Substitutions menu. The allowsEditingTextAttributes property of the text view is enabled which is what makes the Font portion of the menu appear. I want to keep the Bold/Italic/Underline toggles.
I have an Intel Mac running macOS Monterey 12.6. I'm running Xcode 14.2.
I created a new iOS project. I deleted the "Mac (Designed for iPad)" destination and added the "Mac (Mac Catalyst)" destination.
Unlike the iOS minimum deployment target, oddly there is no place to set the macOS minimum deployment target. I had to go to the target's Build Settings and change it there.
I then chose "My Mac (Mac Catalyst)" as the build target and built the project. So far, so good.
I then tried to run the app. I get a dialog with the following message:
Could not launch “SampleApp”
The app is incompatible with the current version of macOS. Please check the app's deployment target.
Clicking on the Details button gives lots of info. Some things I see are:
...
"device_osBuild" = "12.6 (21G115)";
...
"sdk_canonicalName" = "macosx13.1";
"sdk_osVersion" = "13.1";
But I'm not running macOS 13.1. I have macOS 12.6. Oddly there's no mention of the deployment target being set to 12.4 (which I set in the target's Build Settings).
If I go to Xcode -> Preferences -> Platforms, I see "macOS 13.1" listed as built-in. Tapping on the + button there is no option for macOS.
So my question is how do I support running a Mac Catalyst app on an Intel Mac running macOS 12.6 while using Xcode 14.2?
Can it be done? What steps do I need to take?
I've reloaded the project. I've restarted Xcode. I've done a clean build. Nothing changes.
Working on the Mac Catalyst version of an iPad app. I don't know if this is a bug, intended behavior, or a setting I am missing. But how do you change (or what value is used) the app name shown in the main menu and the About box?
For example, let's say my app's "Bundle name" in Info.plist is "MyCoolApp" and the "Bundle display name" is "My Cool App".
When the app is run on iOS, I see "My Cool App" under the icon on the home screen. Perfect. But on the Mac, the app's main menu shows "MyCoolApp". Tapping on that menu includes the "About MyCoolApp" menu. The About box also shows "MyCoolApp" under the app icon. Other standard default menus also reference "MyCoolApp".
I want all of those to show "My Cool App", not "MyCoolApp".
What needs to be changed to get the "Bundle display name" to be used?
As best as I can tell, the only messages sent to a MEMessageActionHandler for processing are those going to the Inbox. I'm trying to write a Mail extension that processes incoming messages, most importantly those that go straight to the Junk folder, but none of those messages go to the extension.
Is there some setting I may be missing or can a MEMessageActionHandler only process emails going to the Inbox?
