    • You will now need to change the coding signing entries in Build Settings to reflect your new Provisioning Profile. Make sure you change the code signing settings under Targets as well as Project.
    • Finally, you need to generate two p12 for each certificate. Go to Keychain and look up for your Apple Push Development Certificate.
    • Then, right-click, export. You should put a password, this password needs to be provided with your p12 for installing on EMMA server.
    • Click the right arrow and repeat the process for your private key. Now you will have two p12, one for the certificate and one for your key.
    • Repeat it for production using the same password
