MissingKeychainEntitlement

The OS refused a Keychain data-protection-store operation with errSecMissingEntitlement (OSStatus -34018). This is not “the binary isn’t signed” — an ad-hoc or Development-signed binary with no keychain-access-groups entitlement at all also gets -34018, and a signed binary that does carry that entitlement with no provisioning profile behind it is killed by the kernel at launch instead. The fix is a team-prefixed keychain-access-groups entitlement backed by an embedded provisioning profile — in Xcode, set DEVELOPMENT_TEAM so automatic signing fetches and embeds one. A build with no team must omit the entitlement entirely, which means it also has no access to the data-protection keychain and will hit this error on first use.

KeychainTemporarilyUnavailable

The OS refused this keychain operation with errSecInteractionNotAllowed (OSStatus -25308): the keychain is locked, the display is asleep, or the login session cannot show UI. Nothing is wrong with the entry or with this process’s entitlements — the same operation succeeds once the session unlocks, so a caller that needs the key should say so and try again rather than treat the store as broken or the key as absent.

Trait Implementations

impl Debug for KeyError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for KeyError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for KeyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
