If this topic was already discussed, I’m apologizing for bringing it back to life in a new thread.</p>
<p>Lets say I’ve got a third party module and I want to know when the a variable of some type has changed:</p>
<pre><code class="swift">extension UIViewController {
public override var view: UIView {
willSet {
// do something useful here
}
didSet {
// do something useful here
}
}
}
</code></pre>
<p>Wouldn’t be handy to inject custom <code>didSet</code> and <code>willSet</code> functions into any property or computed property?</p>
<p>This would also allow us to build a proper two-way-binding mechanism. </p>
