-| `BUILD_CERTIFICATE_BASE64` | Export a Development certificate (.p12) from Keychain Access, then base64-encode it: `base64 -i build_certificate.p12 \| pbcopy` |
-| `P12_PASSWORD` | The password you set when exporting the .p12 certificate. |
-| `BUILD_PROVISION_PROFILE_BASE64` | Download the provisioning profile (.mobileprovision) from [Apple Developer > Profiles](https://developer.apple.com/account/resources/profiles/list).

-| `KEYCHAIN_PASSWORD` | Any random password for the temporary CI keychain. Generate one with: `openssl rand -base64 32` |
