swift :changing the content of an array gives me an error
<p>I have this array :</p>

<pre><code>var array = [[12,46,["a","b","c"],"nil",true,7,true],[10,40,["c","d","e"],"nil",true,7,true],[0,1,["z","l","w"],"hey",false,7,true]].
</code></pre>

<p>when I try to change the value of the last boolean of an array boolean by this code :</p>

<pre><code>array[0][6] = false
</code></pre>

<p>I get this error "cannot assign through subscript subscript is get-only array"</p>
