Failed to verify code signature (resource added!) #66
iResign had worked perfectly with several builds of an app but a recent build failed with this error in the Xcode device log:
: 0x10070c000 -[MICodeSigningVerifier performValidationWithError:]: 186: Failed to verify code signature of : 0xe8008017 (Signed resources have been added, removed, or modified)
Another line in the log reported this:
resource added: /private/var/mobile/Library/Caches/com.apple.mobile.installd.staging/temp.D4oAby/extracted/Payload/[deleted].app/Data/sharedassets1.resource
I unzipped both the original and the re-signed IPA and right-clicked on the App file to "Show Package Contents". Sure enough, the re-signed version has a Data/sharedassets1.resource file which is 14.2Mb in size! The original does not.
The file _CodeSignature/CodeResources does not reference the file sharedassets1.resource in either the original or re-signed App, which is probably the cause of the problem, i.e. the file is appearing from nowhere and is not signed.
I was able to delete the sharedassets1.resource file through File Explorer, re-zip the IPA, and then it installed.
Where in the world is the sharedassets1.resource file appearing from?
