Read-Only properties : <p>I need help with "read-only" in swift. I tried various ways, but simply couldn't figure out how to compile it without errors. Here's the question and what i thought of.</p>

<p>Create a read-only computed property named isEquilateral that checks to see whether all three sides of a triangle are the same length and returns true if they are and false if they are not.</p>

<pre><code>var isEquilateral: Int {

}
</code></pre>
