Codesign verification failed in Xcode for iphone app distribution

Question

Hi,

I am trying to prepare my app for distribution to the app store and am getting the following warning in Xcode which is causing an error in ApplicationLoader. I know this is a common problem from searching but I have yet to find a proper solution? I went thru Apple's steps for distribution on the iOS provisioning portal and still get this error.

My distribution profile is set on my Target.

"Application failed codesign verification. The signature was invalid, or it was not signed with an Apple submission certificate. (-19011)"

Any suggestions?

Answer 1

App distribution certificate is only used for the app store. You will get this error if you try and put an app signed with your distribution certificate on your phone -- it simply won't work.

Answer 2

Do you have a valid iPhone Distribution certificate in your Keychain?

Does the Xcode Organizer Provisioning Profile window show your Distribution provision?

Does your distribution provisioning profile have an app ID that is the same or compatible (wildcard) with the Identifier setting in your Target Info Properties setting?

Edit: added:

Do you have exactly one iPhone Distribution certificate in your Keychain?

Did you do a Build Clean in Xcode before your distribution build? (or rm -rf ./build)

Answer 3

First of all check your Certificate, is it distribution or developer? And it must be Distribution certificate. Follow the step- 1- clean all certificate from your keychain and download new distribution certificate. 2- Also clean remove the distribution provisioning profile what you use for the particular for your this application and re download that one. after that must be clean build in Xcode and after that in project setting you must be select the particular D.P.P. for your application and go a head just only build it. then you get the particular build. 3- Regarding the D.P.P you must be clear what type of profile you create for this. it must be Appstore D.P.P.

I hope it should be helpful for you.
