</li>
|

<li><p>

Swift新增了一个 <a href="https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/BasicOperators.html#//apple_ref/doc/uid/TP40014097-CH6-XID_124" data-id="//apple_ref/doc/uid/TP40014097-CH6-XID_124">Nil合并运算符（Nil Coalescing Operator）</a> (<code>a ?? b</code>), 该表达式中，如果Optional <code>a</code>的值存在，则取得它并返回，若Optional <code>a</code>为<code>nil</code>，则返回默认值 <code>b</code>

<li><p>
