[image-cache-it] src and fallback images with local (~/...) paths don't render in v8.0.1 (iOS)

On iOS, local src or fallback images (e.g. ~/images/flags/flag.png) no longer render. Remote (http(s)://) URLs are unaffected. Works fine in v7.5.0 but not on 8.0.0 or 8.0.1. Android is fine. Environment: NativeScript 9.0.x

In index.ios.js, the ~/ branch of srcProperty.setNative assigns the resolved path string to nativeViewProtected.src, which doesn't seem to handle local paths. Going through setImageSource() instead loads the UIImage correctly, but it still doesn't render. The workaround (which seems to be ok) is to assign to this.imageSource:

if (src.startsWith('~/')) {
  // this.nativeViewProtected.src = this.getFileName(src); // FAILS
  this.imageSource = ImageSource.fromFileOrResourceSync(this.getFileName(src));
}

The same problem exists with fallback images.

Related: placeHolder and errorHolder are declared in common.ts and documented as iOS-supported, but 8.0.x has no code to handle them in iOS. Android still implements both.

Start in index.ios.js at srcProperty.setNative and inspect the ~/ path handling, then compare the Android implementation for fallback, placeHolder, and errorHolder. Check common.ts for the declared iOS-supported properties. Done means local src and fallback images render on iOS, and the documented placeholder and error images are handled there without regressing remote URLs.
