ios - command/usr/bin/codesign failed with exit code 1- code sign error

Question

I'm currently in the process of submitting my first app to the Apple store. I've completed the following processes

1. Obtained a developer account
2. Logged into the Member Center to Create an App ID
3. Used keychain access to request and receive a distribution certificate
4. Obtained a provisioning profile using my id and certificate

When I build the app it runs perfectly in the app simulator and on the actual ipad, however when I switch my app to Archive on iOS Device i have a major code sign error which i've attached below.

codesign /Users/Gaby/Library/Developer/Xcode/DerivedData/RoyalAppInspection-dthvtpxadkslqmhkwdpaqkyujscg/Build/Products/Debug-iphoneos/RoyalAppInspection.app
cd /Users/Gaby/Desktop/RoyalAppInspection

79640A11C8D22589BD337496ABB8443581513846: no identity found Command /usr/bin/codesign failed with exit code 1

I have no idea what to do to fix this, as I've tried to make sure all the other aspects of the process were completed correctly.

One concern i did have was when i clicked the provisioning profile file it would not open and "add to library" wouldn't pop up (i cannot access iphone configuration utility for some reason.) I manually added the .mobileprovision file to my xcode project but i'm thinking this may also be a source of my error.

Anyone, can you please help?

Answer 1

The following steps solved the problem for me. I was having the issue where it was not compiling for the device or archiving, working fine for simulator.

1. Open keychain access.
2. Lock the 'login' keychain.
3. Unlock it.

Clean and build after doing the above steps and everything works fine now.
