Xcode 4 - A signed resource has been added, modified, or deleted

Question

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.

Answer 1

I had the same issue and what worked for me was deleting the Derived Data (in Organizer).
