We’re seeing custom symbol images disappear in CarPlay on iOS 27.0. Their text labels remain visible, and built-in SF Symbols still display correctly.
We reproduced this in a small standalone app using:
- CPGridButton in CPListTemplate.headerGridButtons
- CPListImageRowItemCondensedElement
The custom symbol is an SVG symbol asset loaded from a resource bundle:
UIImage(named: "chapters", in: resourceBundle, compatibleWith: nil)?.withRenderingMode(.alwaysTemplate)
For comparison, the same screen displays the built-in dot.radiowaves.left.and.right symbol.
On iOS 26.6.1, the custom symbol and built-in symbol appear correctly in both controls. On iOS 27.0, the custom symbol is missing from both controls, while the built-in symbol remains visible.
The failing device is an iPhone 13 Pro running iOS 27.0 (24A437), with the sample built using Xcode 27.0 (27A266a).
Has anyone else encountered this? Is this a known regression, or is there a new requirement forsupplying custom symbols to CarPlay?
