Hi guys,
<div class="">My idea is simple, put an access level control token
to the setter of a var</div>
<div class=""><br class=""></div>
<div class="">Right now, we are likely to do something like this in
order to hide the setter:</div>
<div class=""><br class=""></div>
<div class="">
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">fileprivate</span> <span style="font-variant-ligatures: no-common-ligatures;" class="">var</span>
<span style="font-variant-ligatures: no-common-ligatures;" class="">_timestamp:</span> <span style="font-variant-ligatures: no-common-ligatures;" class="">Date</span>
<span style="font-variant-ligatures: no-common-ligatures;" class="">=</span> <span style="font-variant-ligatures: no-common-ligatures;" class="">Date</span><span style="font-variant-ligatures: no-common-ligatures;" class="">()</span></div>
<p style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo; min-height: 24px;" class=""><br class="webkit-block-placeholder"></p>
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">public</span> <span style="font-variant-ligatures: no-common-ligatures;" class="">var</span>
<span style="font-variant-ligatures: no-common-ligatures;" class="">timestamp:</span> <span style="font-variant-ligatures: no-common-ligatures;" class="">Date</span>
<span style="font-variant-ligatures: no-common-ligatures;" class="">{</span></div>
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">return</span> <span style="font-variant-ligatures: no-common-ligatures" class="">self</span><span style="font-variant-ligatures: no-common-ligatures;" class="">.</span><span style="font-variant-ligatures: no-common-ligatures;" class="">_timestamp</span></div>
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">}</span></div>

<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-family: Helvetica; font-size: 12px;" class=""><br class=""></span></div>
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-family: Helvetica; font-size: 12px;" class="">The idea is to do it without using another var, like
this:</span></div>
<div style="margin: 0px; font-size: 20px; line-height: normal; font-family: Menlo;" class=""><span style="font-family: Helvetica; font-size: 12px;" class=""><br class=""></span></div>
<div style="margin: 0px; line-height: normal;" class="">
<div style="font-family: Menlo; font-size: 20px; margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">public</span><span style="font-variant-ligatures: no-common-ligatures;" class=""> </span><span style="font-variant-ligatures: no-common-ligatures;" class="">var</span><span style="font-variant-ligatures: no-common-ligatures;" class=""> timestamp: </span><span style="font-variant-ligatures: no-common-ligatures;" class="">Date</span><span style="font-variant-ligatures: no-common-ligatures;" class=""> {</span></div>
<div style="font-family: Menlo; font-size: 20px; margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">get { </span><span style="font-variant-ligatures: no-common-ligatures;" class="">return</span><span style="font-variant-ligatures: no-common-ligatures;" class=""> </span><span style="font-variant-ligatures: no-common-ligatures;" class="">self</span><span style="font-variant-ligatures: no-common-ligatures;" class="">.</span><span style="font-variant-ligatures: no-common-ligatures;" class="">_timestamp
}</span></div>
<div style="font-family: Menlo; font-size: 20px; margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">fileprivate set(newValue) { _timestamp = newValue
}</span></div>
<div style="font-family: Menlo; font-size: 20px; margin: 0px; line-height: normal;" class=""><span style="font-variant-ligatures: no-common-ligatures;" class="">}</span></div>
<div style="font-family: Menlo; font-size: 20px; margin: 0px; line-height: normal;" class=""><span style="font-family: Helvetica; font-size: 12px;" class=""><br class=""></span></div>
<div style="margin: 0px; line-height: normal;" class="">In this way
the setter will be available “locally” in the file but it will
not be accessible from outside.</div>
<div style="margin: 0px; line-height: normal;" class="">The only
problem that I can see is how to reference the var itself? As you
can see I used “_timestamp” like Objective-C, but there
should be another way to do reference it.</div>
