Xcode 4 - A signed resource has been added, modified, or deleted
ios, signing, xcode
Solution
I had the same issue and what worked for me was deleting the Derived Data (in Organizer).
Problem
Issue: I have created an app, distributed an ad-hoc version and successfully uploaded it under Organizer - Devices. So far so good. Now, i've tried a 2nd app. When i uploaded this one, i get the following message: A signed resource has been added, modified, or deleted. I googeld for a while and tried the following things: - avoid special chars in the projectname - clear the build - delete derived data under Organizer - Projects - renew my Certificate - renew all my provisioning profiles - i've made a new and minimalistic project It failed all. Same message every time. Hopefully someone can help me, please.
