While attempting to debug a build created using the 3.2 SDK on an iPhone device I receive the message \"A signed resource has been added, modified, or deleted.\".
I
solved my issue!!!
I found out by accident that somehow a space " " found it's way into the Product Name of my app so it was called "First Second.app" instead of "FirstSecond.app". After deleting the space the issue was gone!
I changed it here: right click on target Get Info Build Tab Packaging Section Product Name <- The name here will be used for the bundle (.app) name
Hope this helps, let me know!
Cheers, nils
The simplest (and probably most common cause) appears to be rebuilding without any changes.
So the simplest thing to cure it is to make a trivial change to a source file (such as adding a space, then deleting it), and then rebuilding.
If this doesn't work, feel free to try all the other answers here.
For months, I'd get this error without realizing it was due to such a simple cause. I'd usually do a Clean Build to get rid of it.
