I then iterate over it. The problem is, it's a bit cumbersome to write:<br>
<br>
if let container = someOptionalContainer<br>
{<br>
for item in container<br>
{<br>
}<br>
}<br>
<br>
I wish I could just write<br>
<br>
for item in someOptionalContainer<br>
{<br>
}<br>
<br>
such that if the optional is nil, it just skips the iteration altogether.<br>
<br>
Is there a syntax for that (especially in Swift 3)?<br>
