#11042 was missing a `:`,
causing label jobs to fail in CI.

Replaces the Obj-C example app with Swift. Rather than attempt to modify the example in place, I started clean from the Swift template:
- deleted the ios/ directory.
- ran `flutter create --platforms=ios .` using current `stable` (3.41.0).

…tes (#10577)

Adds percentage unit support for SVG shape attributes

  SVG shapes like `<rect>`, `<circle>`, `<ellipse>`, and `<line>` can have percentage values for their position and size attributes (e.g., width="50%", cx="50%"). Previously
  these weren't handled correctly. Easy to test with any image like https://placeholdit.com/600x400/dddddd/999999

  This adds:
  - Percentage parsing in parseDoubleWithUnits that resolves values against the viewport dimensions
  - Viewport width/height getters on SvgParser
  - Proper percentage reference handling for all basic shape elements
  - Circle radius uses the normalized diagonal per SVG spec

*List which issues are fixed by this PR. You must list at least one issue.*

I'm not sure if it fixes these issues, as they have no description. I can file a new issue if needed.
