blocks|key|3235016|text|你的假设很接近，但有一些事情是可以改变的。我将尝试帮助您尽可能接近Objective-C版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3235017|首先，nonatomic和assign在swift中是不相关的。这给我们留下了|offset|length|style|CODE|3235018|@property+(getter+=+isOpen)+BOOL+open;|code-block|syntax|javascript|3235019|因为swift中的属性只是实例变量，所以swift的转换如下所示。|3235020|var+open:Bool|3235021|尽管它具有与Objective-C版本相同的基本功能，但它缺少命名getter+(isOpen)。不幸的是，(到目前为止)还没有直接翻译到swift。您可以使用自定义的getter和setter。|3235022|var+open:Bool+{

Your assumption was close, but a few things could be changed. I will try to help you get as close as possible to the Objective-C version.

First of all, the <code>nonatomic</code> and <code>assign</code> are irrelevant in swift. That leaves us with 

<pre><code>@property (getter = isOpen) BOOL open;
</code></pre>

Since properties in swift are just instance variables, the swift translation would be as follows.

<pre><code>var open:Bool
</code></pre>

Although this has the same basic functionality as the Objective-C version, it is lacking the named getter (<code>isOpen</code>). Unfortunately, there is no direct translation to swift for this (yet). You could use a custom getter and setter.

<pre><code>var open:Bool {
 get {
 // custom getter
 }
 set {
 // custom setter
 }
}
</code></pre>

A rather crude work around would be to make another function literally called <code>isOpen</code> that would act as a getter.

<pre><code>func isOpen() -&gt; Bool { return self.open }
</code></pre>

In conclusion, what you are asking is only slightly possible, but hopefully in later releases of swift can become a reality.

<pre><code>var open: Bool {
 @objc(isOpen)

Leads to this generated header:

<pre class="lang-c prettyprint-override"><code>SWIFT_CLASS("_TtC11SwiftToObjC9TestClass")
@interface TestClass : NSObject
@property (nonatomic, getter=isOpen) BOOL open;
- (nonnull instancetype)init OBJC_DESIGNATED_INITIALIZER;
@end
</code></pre>

blocks|key|2401765|text|作为补充，对于设置器，您需要重复@objc指令：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2401766|@objc(+setOpen:)+set+{+self.open+=+newValue+}|code-block|syntax|javascript|2401767|别忘了半柱。|2401768|一件特别的事情是，在这样做的时候，self.open将调用setter/getter本身并产生一个无限循环。在Obj-C中，您可以使用self->open修复它。如果是swift，该怎么做呢？|2401769|entityMap^0|G|5|0|0|0|H|9|1V|A|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

As a remarq, for the setter you need to repeat the <code>@objc</code> directive:

<pre><code>@objc( setOpen:) set { self.open = newValue }
</code></pre>

Don't forguet the semi-column.

A particular thing is that, doing this, <code>self.open</code> will call the setter/getter itself and produce an infinite loop.
In Obj-C you fix it using <code>self-&gt;open</code>. How do this if swift?

What is the equivalent of the following Objective-C code in Swift?

<pre><code>@property (nonatomic, assign, getter = isOpen) BOOL open;
</code></pre>

Specifically, how does one declare a variable in Swift to synthesize the getter with a custom name?

Furthermore, how can you subsequently override the implementation of the getter and setter?

以下Objective-C代码在Swift中的等价物是什么？@property (nonatomic, assign, getter = isOpen) BOOL open;具体地说，如何在Swift中声明一个变量来合成带有自定义名称的getter？此外，您如何随后重写getter和setter的实现？
