App ID, provisioning profile, and signing certificate
WHAT IT TESTS: the code-signing trust chain. OUTLINE: the certificate proves who you are, the App ID identifies the app and its capabilities, and the provisioning profile binds certificate, App ID, and allowed devices so iOS trusts the install.
WHAT IT TESTS: understanding how the three pieces combine into a trust chain iOS enforces at install and launch. ANSWER OUTLINE: the signing certificate, backed by a private key, proves the build came from an authorized developer; the App ID identifies the application by bundle identifier and declares its entitlements; the provisioning profile ties together the App ID, one or more certificates, and, for development or ad hoc, a list of permitted device UDIDs, all signed by Apple.
