<div dir="ltr"><div><div class="gmail_signature"><div>Hello,</div><div><br></div><div>I'm having an issue with (NS)Calendar on Linux which I think is a bug, but I just wanted to check first if it was just me or if this is indeed a bug. I've filed a bug report here, just in case: <a href="https://bugs.swift.org/browse/SR-2846">https://bugs.swift.org/browse/SR-2846</a></div><div><br></div><div>In short, Calendar has a method date(byAdding:to:wrappingComponents:) which returns a new date which is the result of date arithmetic on the passed-in date. It works fine on El Capitan, but doesn't seem to work properly on Ubuntu 14.04. Below is some sample code:</div><div><br></div><div><pre class="gmail-code-java" style="margin-top:0px;margin-bottom:0px;padding:0px;max-height:30em;overflow:auto;white-space:pre-wrap;word-wrap:normal;color:rgb(51,51,51);font-size:12px"><span class="gmail-code-keyword" style="color:rgb(0,0,145)">import</span> Foundation
let today = Date()
let diffComponents = DateComponents(day: -1)
let newDate = Calendar.current.date(byAdding: diffComponents, to: today) <span class="gmail-code-comment" style="color:rgb(128,128,128)">//returns nil</span></pre></div><div><br></div><div>I've tried this in the swift REPL on Ubuntu 14.04 with both Swift 3.0-RELEASE, and the latest snapshot (October 2).</div><div><br></div><div>If anyone else could try this out as a sanity check for me, that would be great - I'd be happy to be embarrassed that I've done something wrong.</div><div><br></div><div>Thanks,</div><div><br></div><div>Jason</div></div></div>
