Adobe XD throws error when loading UIKit resources Sketch file
Hi there. I want to use Adobe XD for designing and prototyping apps, and I would like to get the UIKit design resources working. I downloaded it and tried to open it with Adobe XD, but it threw this error: There was an error opening the file Apple iOS 26 UI Kit.sketch (Error code: 115) I really prefer to use the UIKit in Adobe XD rather than paying for Figma or Sketch. Thanks. Apple Design Resources

Maintain app icon contrast when switching to grayscale mode
Context & Issue I am developing an iOS application. My app icon uses colors that are relatively close to each other. When the user enables Accessibility → Display & Text Size → Color Filters → Grayscale (or similar modes), the icon becomes harder to distinguish because it loses color and contrast is reduced. Goal When iOS switches to grayscale mode, I want the app icon to maintain good contrast between its elements so it remains clearly recognizable. What I’ve tried Redesigned the icon with more contrasting colors. Added strokes/outlines, but it still doesn’t look much better in grayscale. Researched how iOS renders app icons when grayscale is enabled, but couldn’t find a way to override or provide an alternative icon. Specific questions Is there any API or mechanism in iOS that allows providing a different version of the app icon when the user has grayscale mode enabled? If there’s no direct API, are there any best practices for designing iOS app icons to ensure good contrast when converted to grayscale? Do we have to design grayscale version for app icon? Thank you!

Swift Playground with C language.
I want to know if the program written in C language can be implemented through the software package, write a software package containing C language on Xcode, and then apply it in Swift Playground.

Need Help Moving INRx App to New Developer Account – Design Issue Blocking Submission
Hello Apple Developer Support, We initially uploaded our INRx App on a different Apple Developer account for internal testing purposes. Now, we would like to publish the same app under a new Apple Developer account for production, but we're currently facing a design-related rejection during the review process. We believe the app meets all guidelines, and there were no design issues flagged previously when submitted from the testing account. Could you please help us understand: Why the same app is now being rejected for design issues? Is there a way to resolve this while moving the app to the new account? Any advice or clarification would be greatly appreciated so we can successfully proceed with publishing. Thank you!

New to macOS Development. How Do I Build a Timeline Editor UI Like Logic Pro?
Hi everyone, I’m new to macOS development and working on an app idea that needs a timeline-based editor interface, similar to what you see in Logic Pro or Final Cut. The UI I want to build would have: A horizontal beat ruler that follows BPM and shows beat positions Several vertical tracks stacked below it (for things like events or markers) Horizontal zooming and scrolling A preview panel on the right side that stays in sync with the timeline I’m currently trying this in SwiftUI, but I’m running into some limitations and wondering if AppKit would be a better fit, or maybe a hybrid of the two. My questions: Where should I start when building something like this? What’s the best way to make the beat ruler and all track layers scroll together? How should I handle zooming in/out and syncing the display to a BPM timeline? Is there a clean way to integrate AppKit for the timeline view while keeping SwiftUI elsewhere?

How can I force a function only runs once during the whole app lifecycle?
Hi, I want to generate some sample datas for demonstrating the functions of my app when the app launched. My codes are as followings: func generateSampleData() { let hasLaunchedKey = "HasLaunchedBefore" let defaults = UserDefaults.standard if !defaults.bool(forKey: hasLaunchedKey) { //generate the demo data } defaults.set(true, forKey: hasLaunchedKey) } And I put the func in a view's onAppear modifier. I found every time I go the view, it generates the demo data again, which results in producing a lot of demo data. But I have set the status of the function running in the userdefault. Why did it happen? Best Wishes,

Liquid glass - precent automatic color changes
I have an app that displays a MapView. While I am in light mode everything is fine. I can scroll around the map and my overlays (made by UIVisualEffectView containing an UIGlassEffect) stay light and look well! As soon as I change my phone to dark mode, depending on what's underneath the buttons (a light residential area or darker wooded areas) some of my buttons change color. But not all, only where it's supposedly lighter or darker underneath. This makes my whole UI look strange. Some buttons bright, some dark. Is there a way to lock a "color" or interfaceStyle to the effects-view? In light mode everything is fine, but in dark mode it just looks super strange.

App crashes on click NEXT to next View
I am developing an app in Swift Playground (No Xcode). All my Views respond to the navigation call when I click NEXT except one. When I click NEXT the app hangs then crashes. The error message does not identify the cause of the crash. I have research every possible lead with no success. I would like to get some ideas on how to resolve this issue.

Can't get a simple network call working. Novice developer.
Here is my code and the error code being generated during build. let myString : String = "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=AAPL&apikey= D5GY7HKODE66G0T9" var banjo = URL(string: myString) let task = URLSession.shared.dataTask(with:banjo ) { myDatastring , response , error in} // task.resume() I've tested that URL in my browser and it works. But when I try to build I get: Value of optional type 'URL?' must be unwrapped to a value of type 'URL' Please tell me what I'm doing wrong. I think the URL struct is not returning a URL type of object.

Always use new animation in Stage Manager, why not?
The brand new animation in Stage Manager greatly reduced dizziness. However, don’t know why it ONLY applies when no window was presented. What would be the problem elsewhere? Stage Manager is one of pretty few motion pictures that annoyed me and forced me to turn on Reduce Motion, or stop using Stage Manager. Big pity… macOS 26.0 (25A5346a) wont use ipad to post…

Icon composer won't allow me to import any files
I have been battling the new Icon Composer app for 2 days trying to build an app icon. However, I cannot get it to import any files. I have used the Apple provided App Icon Template. I have exported my layers to .svg and when I open the finder, everything is disabled. I can't find help for this anywhere. I am on Sequoia on my Mac and not sure how to design this app icon without access to the composer.

IOS 26
H ello there. I just installed IOS 26 on my iPhone 15 Pro Max. But i think i found a Bug with a Widget where you have an overview of all devices and their battery. In IOS 18 when we used the Dark Theme (Dark Icons etc.) this widget was dark aswell (look at the picture) and now in IOs everything is dark except this widget. Its kinda annoying…

Categorize Contacts
I would really like to be able to categorize my contacts. I work for a grocery store and have contacts from various companies. I would like to be able to categorize them by company or group them as I see fit. Currently, I don't see a way to do this. Please add this in a future update. Having all contacts just alphabetically is not efficient enough. Also, I would like to be able to manually adjust the size of widgets. i.e. If I want more stocks to be visible, I would like to be able to lengthen the height/width of the widget beyond what it currently allows to view more information. Thank you. If you have any follow-up questions, please let me know. Torrey
