Singleton Overlaps?

<p>I have two classes using as singletons.</p><pre><br /><code>class Boss {<br /> static let sharedInstance = Boss()<br /> private init() {} <br /><br /> var user_id : String?<br /> var username : String?<br />}<br /><br /><br /><br />class Job {<br /> static let sharedInstance = Job()<br /> private init() {} <br /><br /> var job_id : String?<br /> var JobType : String?<br />}<br /></code><br /></pre><p>But after populating the <code>Boss.sharedInstance</code> first, <code>Job.sharedInstance</code> also containing Boss' class variables. But after replacing the <code>sharedInstance</code> with other name (for eg. <code>job_sharedInstance</code> and <code>boss_sharedInstance</code>) respectively, things are working fine. It's quite weird. Can anybody explain me the reason why it would happen like this. Thanks in advance.</p><br /><h2>Click here view more answers <a href="%20http://stackoverflow.com/questions/34525828/singleton-overlaps">http://ift.tt/1YSl1Zb</a></h2>
