CFBundleVersion in the Info.plist Upload Error

Question

"The binary you uploaded was invalid. The key CFBundleVersion in the Info.plist file must contain a higher version than that of the previously uploaded version."

I’m getting this error when I come to upload my application.

I set the updated version to 1.2 on iTunes Connect and have also updated the .plist file to 1.2.

I don’t understand why I am getting this error. Any help would be appreciated. Thanks.

There's at least 1 known bug in Apple's upload server that they've not fixed for more than 12 months. Things to beware of:

1. Apple deletes any leading zeroes inside the version number; i.e. the "whole string" is NOT treated as a number, instead the bits between dots are treated as SEPARATE numbers. e.g. "1.02" is treated by Apple as "1.2". So, for Apple, 1.02 is GREATER THAN 1.1
2. Apple sometimes gets "confused" and seems to compare your uploaded-app to the version of a DIFFERENT app you've previously uploaded. It's happened to a lot of people, and I've seen it myself a few times
3. Apple is supposed to be comparing the "CFBundleVersion" (i.e. "Bundle version" not the "Bundle versions string, short"); don't get mixed up.
4. Frequently, the only viable solution is to bump the front number (e.g. the "2" in "2.4" -- increase it to "3")
5. The version number you upload is unrelated to the version number that appears in iTunes - you can put anything you want there, and that's what your users will see
6. ...except, if you also report the "actual" version number inside your app, the user will see the CFBundleVersion (usually, depends how you code it), rather than the iTunes version (which - I think - cannot be accessed from inside your app)
