Yattee 2 keys credentials by instance UUID with no notion of which Apple
account they belong to, and reads them back with SynchronizableAny. Apple
documents that Keychain data may stay on device when a user signs out and
chooses to keep it, so whoever signs in next would be served the previous
user's credential - guaranteed for migrated accounts, since local instances
survive the switch and the migrated account UUID is deterministically the
instance UUID.
Credentials are now keyed "<identityScope>|<accountID>", where the scope is
the CloudKit user record (identical across a user's devices, so iCloud
Keychain sync still works). Usernames get the same scope and live beside the
credential, keeping login identifiers out of synced metadata.
The legacy unscoped item is never adopted automatically. A strict
kSecAttrSynchronizable == true query was the candidate discriminator for
"this secret belongs to the current Apple account", but measured on iPadOS
27.0 a retained item keeps the attribute and still matches that query with
no Apple account signed in at all - the flag records what was once requested,
not live iCloud Keychain membership. Reads therefore never fall back to the
legacy key; adoption is an explicit user action that copies the item,
verifies the scoped read-back, then records a marker bound to the identity
and a salted fingerprint of the secret. The legacy item is retained, because
deleting a synchronizable item propagates and would log out devices still on
the previous release mid-rollout. Deleting it later needs all three of: a
marker on this device, matching identity, and the item still holding the
adopted secret.
The instance-keyed path is untouched, so no shipping call site changes
behavior. BasicAuthCredentialsManager stays instance-keyed - proxy auth
belongs to the instance, not to a user account.
While the scope is unresolved (first launch under a new Apple account,
CloudKit unreachable) reads report "can't tell yet" via isScopeResolved
rather than "signed out", and writes are refused rather than guessing a
scope. Login state is cached per scope so one identity's cache can never
answer for another.
Also adds the debug-only harness the measurement was taken with, under
Advanced > Developer > Experiments.
Extend SettingsFormSection to accept a @ViewBuilder footer for sections
with dynamic multi-line content (last background refresh, orphaned
files status). Move trailing button accessories (size, progress) out of
button labels so buttons size to their content on macOS.
Delete the multi-page onboarding sheet. On first launch the app now
silently imports any v1 instances from UserDefaults (splitting embedded
basic-auth credentials out of the URL and into the Keychain) and then,
if the device is signed in to iCloud, shows a single alert offering to
enable sync. Accepting shows a blocking progress overlay until the
initial upload completes.
Replace the tvOS bottom action bar with Settings / Info / Comments /
Next / Close. Settings reuses QualitySelectorView (video, audio,
subtitles, speed); Comments opens TVDetailsPanel directly on the
comments tab; Close stops playback and dismisses.
Debug button is hidden by default and can be re-enabled via a new
tvOS-only Advanced Settings > Developer toggle.
Present the settings sheet as a fullScreenCover with a centered
material card, fix the "Normal" hyphenation, and restyle row selection
throughout the quality selector on tvOS: per-row rounded backgrounds
with focus tint + stroke, vertical spacing instead of dividers, and a
focusable speed-rate menu.
