Hey, you need to read the parent a bit closer.<p>Nobody&#x27;s saying that Xamarin uses web views, but clearly there&#x27;s a comparison to be drawn with the craze a few years back for writing mobile apps using web views. This was advocated as being cross-platform, allowing developers to write the same code and run it on multiple platforms. The downsides are the same in some ways, as the parent enumerated.<p>Xamarin&#x27;s use of native UI is important, but in my experience it&#x27;s clearly not as seamless as you think; while you access the UI natively, there are intrinsic architectural differences that make it difficult to do so in a high-performance manner without a lot of fairly hacky code.
