Sparkle Always Up To Date

Question

I recently added the Sparkle Framework [ http://sparkle-project.org/ ] to my cocoa application. When I add a dummy new item (version 1.1) to the appcast.xml, and subsequently try to update from version 1.0, it says "XXX 1.0 is currently the newest version available".

I've been at this for a while, and I've read the documentation [ https://github.com/sparkle-project/Sparkle/wiki ] quite a few times, with no success.

Here is my Info.plist:

<?xml version="1.0" encoding="UTF-8"?>

And my appcast.xml (renamed to Snappi.xml):

Thanks!

Addition: Thinking about this more, should this result in behavior different from "You're already up to date" ? I feel like it would but I'm not sure.

Answer 1

Sparkle compares the sparkle:version attribute in the appcast to the CFBundleVersion in your plist (this is machine-readable versions).

So, here, your CFBundleVersion (100) indicates you have a newer (>1.0) version that what is in the appcast.

On the other hand, CFBundleShortVersionString (which corresponds to the sparkle:shortVersionString in the cast) is used for "user displayable" versions.

Answer 2

I suggest sticking with the Major.Minor.Batch (0.4.12) versioning, and keep them the same on the app cast and in the info.plist file (CFBundleShortVersionString) of the project itself. you may also try this hassle-free build server that integrate seamlessly with Sparkle http://amtourky.me/2016/01/20/mac-os-x-continuous-delivery-sparkler-the-missing-build-server-for-sparkle/
