Description

Only building an iOS app, so can't talk for Android, but when the following is run, the svg appears but not the animation. I have tried importing the animateTransform property too, still not working.

  <Svg
    width="38px"
    height="38px"
    viewBox="0 0 38 38"
    xmlns="http://www.w3.org/2000/svg"
    stroke="blue"
    aria-label="spinner"
  >
    <G fill="none" fillRule="evenodd">
      <G transform="translate(1 1)" strokeWidth="2">
        <Circle strokeOpacity=".5" cx="18" cy="18" r="18" />
        <Path d="M36 18c0-9.94-8.06-18-18-18">
          <animateTransform
            attributeName="transform"
            type="rotate"
            from="0 18 18"
            to="360 18 18"
            dur="1s"
            repeatCount="indefinite"
          />
        </Path>
      </G>
    </G>
  </svg>

Contributor guide

Research direction
Investigate why animateTransform is not supported on iOS in react native svg. Check the native rendering code (likely in Objective C or Swift) for the SVG element handling and see if animateTransform is implemented or if there is a missing mapping.
