Sparkle appcast not working - sparkle

Question

I'm having a problem getting Sparkle to read my appcast which is in my website's root:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0" xmlns:sparkle="http://www.andymatuschak.org/xml-namespaces/sparkle" xmlns:dc="http://purl.org/dc/elements/1.1/">

<enclosure url="http://yWebSite.net/downloads/myApp.zip" sparkle:version=“6.2” length=“1500000” type="application/octet-stream" />
<sparkle:minimumSystemVersion>10.10</sparkle:minimumSystemVersion>
</item>
</channel>
</rss>
In my app I've added a user preference:
[prefs setObject:#"http://www.myWebSite.net/appcast.xml" forKey:#"SUFeedURL"];
[prefs synchronize];
When I select my 'Check for updates' menu item Sparkle reports it doesn't seem to like the feed and logs:
Sparkle: Error: An error occurred in retrieving update information. Please try again later. An error occurred while parsing the update feed.
I've seen this post but it's solution doesn't seem to have helped (although Sparkle did work ok when I used the sample appcast). Presumably my appcast is wrong. I'd appreciate some help in correcting it.

Make sure the sparkle feed is being served on HTTPS or mark 'Allow Arbitrary Loads' to YES in your Info.plist
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
