The types of companies that hire iOS developers and build iOS apps also hire android developers and build android apps, again, IME.
For cases where portability or development time is valued more than having perfect Apple-HIG-compliant UI polish, there are lots of better options. Since Apple has flattened their Aqua interface out of existence down to mostly just gray text labels, even Electron apps started looking good-enough.
Could you give some examples? Most people I talked to really hate React Native, for example. Ionic doesn't seem to have gained enough momentum. You mention Electron, but the last time I checked it's only for the desktop, not mobile. Each year new options appear, but I'm not sure they are that great.
