&gt; Few.swift lets us express UIs as stateless, composable, immutable-ish values of their state. When their state changes, Few.swift calls a function to render the UI for that state, and then intelligently applies any changes.<p>arent most Objective-C and Swift views written like this already?<p>in the .h:<p><pre><code>    @property Klass *model;

</code></pre>
in the .m:<p><pre><code>    - (void)setModel:(Klass *)model {
      if (![model isEqual:_model) {
        _model = model;
        &#x2F;&#x2F; ... stuff like self.text = model.value ...;
        [self setNeedsLayout];
      }
    }</code></pre>
