iOS: How does Keychain maintain application isolation?

I know that each app has their own Keychain which cannot be accessed by any other apps. How does iOS enable this "privacy"?

Looking at an example from KeychainAccess:

let keychain = Keychain(service: "com.example.github-token")
keychain["kishikawakatsumi"] = "01234567-89ab-cdef-0123-456789abcdef"

What exactly will prevent another app from running this same code and accessing your kishikawakatsumi data?

From the Keychain Services documentation of Apple.

Note: On iPhone, Keychain rights depend on the provisioning profile used to sign your application. Be sure to consistently use the same provisioning profile across different versions of your application.

Keychain Access Controls

iOS: iOS gives an application access to only its own keychain items. The keychain access controls discussed in this section do not apply to iOS.
