# When building my Cordova app, I get an error saying “invalid signature”. How do I resolve that?

Once the `ios` platform is added to your Cordova project, you must manually configure the signature of the application on the iOS side of things via the *.xcworkspace* of the app. The *.xcworkspace* can be found in `platforms/ios`. 

After opening the *.xcworkspace*, please go to the “Build Settings” and configure the “Signing & Capabilities” section.
