I'm getting the weirdest error today.
"The application does not have a valid signature"
I get this error when I try to run the application from Xcode 4.3 on my device. Also when I archive it shows it as a generic archive instead of a real app.
Of course I deleted all of the invalid profiles, cleaned my derived data, cleaned my target, and restarted. No luck.
EDIT: Turns out that I had a folder reference in my app. I removed all of the references to the folders and made them groups and it worked!

Just throwing this out there, might help someone in the future (and also would be good for my future reference).
I have a bigger project with 2 projects within (an API and the main project that is running on the device itself and which uses the API).
I have solved this problem by cleaning both projects and then rebuilding them.

Ohhh...Cleaning the Project solved my problem..cheers :)

Basically you cannot have a folder reference called "resources"! I changed to "rsrc" and magic.

You can get a more detailed error message in the device log, which is extremely valuable for debugging this issue.
In XCode 7.3: Window -> Devices -> Select your device -> At the bottom there is an error log with detailed information.
For example in my case it outputs something like this:
Failed to install application at file:///var/mobile/Media/PublicStaging ... : Error Domain=LaunchServicesError Code=0 "(null)" UserInfo={Error=ApplicationVerificationFailed, ErrorDetail=-402620391,
ErrorDescription=Failed to verify code signature of
/private/var/mobile/Library/Caches/com.apple.mobile.installd.staging/temp.iKT2NH/extracted/XYZ.app
/Frameworks/Raygun4iOS.framework : 0xe8008019 (The application does not have a valid signature.)}
So in my case it is somehow caused by the Raygun framework that I have installed.

Also, make sure that when you go to Product > Scheme > Edit Scheme the Build Configuration is set to Running.

I struggled with this for a few hours, but it seems that if you have a framework listed under "Embedded Binaries" as well as being imported through a swift bridging header, this error comes up. I am running XCode 8 with iOS 10. I would try removing your framework from the embedded binaries tab under general settings of your XCode projects. Hope this helps out some person in the future!
