How to fix "Command /usr/bin/codesign failed with exit code 1" error

I am trying to code sign my first app but I can't get it to compile and it keeps giving me the Command /usr/bin/codesign failed with exit code 1 error

To code sign the app I followed the tutorial at this link:

https://ioscodesigning.com/generating-code-signing-files/

I've already checked my keychain for a duplicate certificate, cleared my Derived Data, and selected my provisioning profile in build settings. I don't quite understand Info.plists and bundles so it may be a problem with one of these, but I'm not sure.

I also tried the first answer below about the signing identity for the app. After I added my provisioning profiles, the error went from

Any ideas what the problem is?

Solution

Your issue is probably caused by the wrong signing identity you have selected

Signing Identity: "-"

Seems to be an invalid signing identity

Try to select a valid signing identity on your project's signing settings:

Target build settings -> Signing
