Struggling creating a custom SF Symbol: The provided variants are not interpolatable
Hi, I am trying to create a custom SF Symbol from an SVG file created with Affinity Designer but, even though my SVG file look perfect in Firefox for example compared to the exported custom.circle.svg file (as recommended in Apple's documentation), I fail to get rid of this error: "The provided variants are not interpolatable" My creation process using Affinity Designer is: Export as SVG file Duplicate the custom.circle.svg file exported from the SF Symbols app In the new file, replace the 3 "path" tags in the "g" sections "id="Black-S", "Regular-S", "Ultralight-S" with the paths from the SVG file exported from Affinity designer Set the 3 transform matrices to "matrix(1 0 0 1 0 0)" for the 3 variants to be generated at the correct location. Verify in an SVG viewer that the file looks correct. Import the file via Drag&Drop into the SF Symbols app. What is wrong with my file? Thank you in advance for any help, Marc mySymbol.svg.txt

Live Weather Radar Overlay in CarPlay Maps
Hi all — I wanted to share an idea I recently submitted through Feedback Assistant that I think could improve safety and usability for drivers using CarPlay: Add an option to overlay live weather radar (rain, snow, storms, etc.) directly onto CarPlay Maps while navigating. Similar to how traffic conditions are shown now, this would allow drivers to visually track incoming weather in real time without switching apps or relying on separate devices. Why this matters: • Enhances driver safety by increasing situational awareness • Helps with trip planning and route adjustments around severe weather • Reduces distractions by integrating everything into one screen • Useful for everyday drivers, long-haul travelers, and first responders I submitted this via Feedback Assistant, but I’d love to know what others think. If you also see value in this feature, consider submitting your own version via Feedback Assistant so Apple sees there’s interest. Let’s push for smarter, safer navigation — thanks for reading!

Handling Context Save Errors

CPContactTemplate does not display buttons iOS26
I'm trying to display CPButtons (CPContactCallButton, CPContactMessageButton) in CPContactTemplate. They are displayed using device with iOS16, but with iOS26 device CPContactTemplate only displays contact image and contact name. No buttons. Is it a bug? I don't have iOS17/18 devices to try.

UITabBarController with sidebar on iPadOS 18
When I create a tab group for the sidebar on iPad, the title and disclosure triangle act like a single control. Every time I tap the section title, the disclosure triangle for that section activates and hides or exposes that section's children and actions. I want the section title to behave like Photos, where tapping a section title just displays its view controller, and the disclosure triangle is a separate control that must be tapped to hide and show children and actions. I did not see any delegate methods that would let me control this behavior. Is this supported?

How to create a custom SF Symbol using Affinity Designer
When I first tried to create a custom SF Symbol using Affinity Designer, I encountered difficulties because of two problems which have cumulated: SVG files created by Affinity Designer cannot be directly imported into the SF Symbols app because Affinity Designer totally recreates the content of tag <g id="Notes">, making so the file incompatible for later import into the SF Symbols app. So I had to manually fix that tag via a text editor in order to make the file compatible with the SF Symbols app. Because I was so focused on fixing manually the SVG file, I did not see that the actual content of my SVG file did not follow all Apple recommendations. As a consequence, I have posted this question on the forum: Struggling creating a custom SF Symbol: The provided variants are not interpolatable Finally I have found a way to create an SVG file compatible with SF Symbols using Affinity Designer, meeting the Apple recommendations, and at last perfectly suitable for further use in Xcode. You will find the solution in my reply to this post below which is actually a quasi copy/paste of my final own reply to my original post. Marc

tvOS alternative app icons
Does anyone know if alternate app icons are actually supposed to work for Apple TV projects? We tried to set this up, and while it works in Debug, we run into validation errors when uploading the app to App Store Connect. Is this feature officially supported on tvOS, or is it iOS-only?

Getting original LocationNode from hit tested SCNNode
I would like to modify the content of a published LocationNode upon been clicked by the user. But unfortunately: func hitTest(_ point: CGPoint, options: [SCNHitTestOption : Any]? = nil) -> [SCNHitTestResult] returns an SCNNode array from which it is impossible to retrieve the original LocationNode being inserted in order to be able to modify it. Of course the solution would be to either insert the SCNNode corresponding to the inserted LocationNode in a custom class or conversely insert the identifier of the custom object as a tag of the LocationNode, in order to solve the issue. But both options seem impossible to implement. May anyone help me?

Repost : Analog Clock on lock screen
When we are going to have a real analog clock option on the lock screen. If an apple watch can do it surely its not that difficult. For someone who uses a clock to tell what time it isn't as opposed to what time it is, i’m constantly having to convert a digital image where the image of hands on a dial is so much easier. Surely this isnt because someone has forgotten how to read a clock

Novice SwiftUI developer can't make network call
I'm trying to use URL structure in the foundation framework and it is failing to build, returning a nil value. Could it be trying to evaluate the string I am giving it as a variable for its argument at build time? Is there a test argument I can give URL to see if it can return a non-nil value? (of URL type)?

New in SF Symbols 7: ipod.and.vision.pro.
Why? Why stop there? (Why not ipod.and.imacg3? applenewton.and.vision.pro?) I get why the older ipod symbols exist but these new pairings are odd. If anyone ever sees these restricted symbols in the wild, or even just someone using a Vision Pro and an iPod (Touch) together in a way that's not contrived, please do let me know!

Should we design for Liquid Glass on visionOS?
Liquid Glass was introduced as a universal design language for all platforms, but isn't supported by visionOS 26 beta. For a small team creating a visionOS app targeted for release in fall 2026, should we focus our design work on Liquid Glass, or for the existing visionOS design language?

Liquid Glass Navigation Bar
The system provided liquid glass background looks terrible with my companies navigation bar background color. The navigation background color is not up for discussion and cannot be changed. The clear liquid glass style looks great and I can apply that to buttons I add to the navigation bar, but that doesn't effect the system provided back button. I would prefer to maintain the default back button functionality. Please make it possible to set the liquid glass style that the system provides for navigation bar items.
