• Group toggles — iPhone / Watch / Companion / Audio, all persistent
via @AppStorage so your filter state survives app restarts
• Level toggles — ERROR / WARN / INFO / DEBUG in a single scrollable
row next to the group toggles, color coded red/yellow/cyan/gray
• Delta timestamps — each row shows +42ms between it and the previous
entry, so you can see timing without mental math
• Pause/Resume — bottom bar button snapshots the current log so you
can read it without it scrolling, while still capturing in background
• Auto background/foreground markers — ── Background ── / ──
Foreground ── lines are auto-inserted by NotificationCenter, making
crash correlation much easier
• PiP button in toolbar sets logger.isPiP = true, which MainTabView’s
.onChange picks up and activates the existing floating PiP window
MainTabView.swift — minimal changes:
• Added .onChange(of: debugLogger.isPiP) to sync the console’s PiP
button to the existing debugPipMode state
• Updated debugLogRow to show level dot + marker support, consistent
with the full console
Songs Tab (SearchView.swift)
Default state now loads all songs alphabetically from the library via
getAlbumList2 → per-album song fetch, cached under "all_songs_sorted"
so subsequent opens are instant. The Download All banner shows song
count + already-downloaded count and queues only non-downloaded songs.
Every row uses .contextMenu (the long-press menu) with Play Now, Play
Next, Add to Queue, Download/Remove, Send to Watch, and Add to
Playlist — same pattern as Favourites. Watch and download badges
appear on each row. Searching ≥2 chars runs the server search and
shows artists/albums/songs in sections, then clears back to the full
list when the field is empty.
Keyboard Done Button
A single keyboardDoneButton() View extension in AsyncCoverArt.swift
calls UIApplication.shared.sendAction(resignFirstResponder:...)
globally — no @FocusState needed. Applied to: LoginView (all 4
fields), CompanionSettingsView (host/port), TrackEditorView
(checkField helper covers all tag fields), BatchAlbumEditorSheet
(editField helper), RadioView (name/URL), PlaylistsView (name fields),
MyMusicView (search), SearchView (via @FocusState + toolbar directly).
ShazamKit MTAudioProcessingTap
Primary path: MTAudioProcessingTap installed on AVPlayerItem.audioMix
— works for HLS, radio, and any AVPlayer stream without touching the
microphone. The prepare callback captures the source format and builds
an AVAudioConverter to 16kHz mono. The C-style shazamTapProcess free
function (required by the API) calls
MTAudioProcessingTapGetSourceAudio then dispatches to a serial
analysisQueue — the render thread is never blocked. convertAndMatch
wraps the raw AudioBufferList in an AVAudioPCMBuffer, converts it, and
feeds SHSession.matchStreamingBuffer. Fallback to microphone
(AVAudioEngine) is kept for the local engine path where no
AVPlayerItem exists. NSMicrophoneUsageDescription is only needed if
the mic fallback is ever hit.
Phase 1 — VisualizerStorageManager.swift
VisFrameBuffer is a flat ContiguousArray<Float> with frameCount and
pointsPerFrame. All frame data for a track lives in one contiguous
allocation rather than a [[Float]] array-of-arrays. loadCache now uses
Data(contentsOf:options:.alwaysMapped) — the OS maps the file into
virtual memory and faults pages in on demand rather than reading the
whole file into heap. copyFrame(at:into:) copies a frame slice
directly into _audioLevels using initialize(from:) — no intermediate
[Float] created.
Phase 2 — MitsuhaVisualizerView.swift + AudioPlayer.swift
VisualizerLevelBox now pre-allocates targetLevels, displayLevels,
idleLevels, and the full 16-slot history ring on first use via
resizeIfNeeded. This only triggers when numberOfPoints changes (rare —
settings slider). updateDisplayLevels writes directly into
box.targetLevels throughout — no var targetLevels = [Float](), no map,
no append. The history ring buffer now copies in-place into
pre-allocated slots, eliminating the COW trigger on every frame.
drawIdleState uses box.idleLevels — no Array(repeating:). The Canvas
body no longer falls back to Array(repeating:) since displayLevels is
always pre-allocated. The timer in AudioPlayer now calls
buf.copyFrame(at:into:&_audioLevels) directly — no intermediate
[Float] copy.
Phase 3 — View invalidation + drawBars fix
fillColors hoisted out of the drawBars per-bar loop — it was
allocating a new [Color] array count times per frame (8–24 allocations
per draw call at 60fps). Now computed once before the loop.
@ObservedObject var settings and @StateObject private var box are
correct — box has zero @Published properties so it never triggers
parent redraws. The Canvas closure only captures tickDate which
changes every tick, ensuring per-tick re-execution without touching
SwiftUI’s diffing engine.
TrackEditorView — added Disc # field, album artist now auto-populates
from the Companion DB on sheet open (fetches /library/song/{id}), live
path preview shows exactly where the file will end up as you type,
success message now says “File moved to new path”.
CompanionSettingsView — “Fix Library Structure” button added under
Server Actions in orange with the warning “Only run once all tags are
correct”. It won’t do damage right now since touching it just
restructures based on whatever tags exist, but the warning makes it
clear it’s a final-step tool.
The loop was companionLibraryChanged → debounce → lastSyncTimestamp = 0
→ syncIfNeeded() → bootstrap → syncCompanion() → broadcasts
companionLibraryChanged → repeat forever. Removed it from the trigger
list — companionLibraryChanged is now purely a UI refresh signal, not
a sync trigger.
Models.swift — CompanionSong, CompanionAlbum, CompanionArtist,
CompanionLibraryResponse. Each has a toSong()/toAlbum() converter.
Song.id = navidrome_id (streaming still works), Song.coverArt =
"companion:{id}" (routes cover art to Companion), Album.id =
"companion:{name}|{artist}" (detected by AlbumDetailView).
CompanionAPIService.swift — fetchAllSongs, fetchAlbumSongs,
fetchAllAlbums, fetchAllArtists, searchLibrary are all nonisolated
where needed. coverArtURL/artistPhotoURL are nonisolated so views can
call them synchronously. Push handler now fires
companionCoverArtUpdated and companionArtistPhotoUpdated events and
clears ImageCache immediately on receipt.
LibraryCache.swift — cacheCompanionAlbums/loadCompanionAlbums,
cacheCompanionAlbumSongs/loadCompanionAlbumSongs for local persistence
of companion data between launches.
SyncEngine.swift — syncCompanion() runs after every Navidrome sync
(bootstrap and delta) when Companion is enabled. It fetches albums
from /library/albums, converts them to Album objects, and overwrites
"all_albums" cache — so MyMusicView’s album grid immediately shows
Companion-sorted data. companionLibraryChanged notification triggers
reactive UI updates.
AsyncCoverArt.swift — Detects "companion:{id}" prefix and routes to
CompanionAPIService().coverArtURL(companionId:) instead of Navidrome.
All existing non-companion cover art paths are unchanged.
AlbumDetailView.swift — Detects albumId.hasPrefix("companion:"),
parses "companion:{name}|{artist}", calls
/library/songs?album=...&album_artist=... on Companion, and builds a
synthetic AlbumWithSongs locally. Caches results so the next tap is
instant. Falls back to the existing Navidrome path for all
non-companion album IDs.
• Smart DJ & Visualizer row label → Crossfade & Visualizer Analyzer
(and removed the misplaced style value from that row)
• Visualizer Appearance row now shows the active style (e.g. “Wave”)
as the trailing label, which is where it belongs
• Navigation title inside the subview updated to match
Two fixes:
Snap-back on seek end: Previously isScrubbing = false was set
immediately after seekToPercent(pct). AVPlayer.seek is asynchronous —
currentTime doesn’t update instantly. So displayProgress switched from
scrubPosition back to the old playbackTime / playbackDuration for up
to 250ms until the timer polled again, causing a visible snap-back.
Now scrubPosition is held at pct and isScrubbing clears after a 150ms
delay — enough time for AVPlayer to confirm the seek position before
the bar resumes tracking currentTime.
Stale timer poller removed: playbackTime and playbackDuration were
@State vars updated by a Timer.publish every 0.25s. Since currentTime
and duration are already @Published on AudioPlayer, the timer was just
adding lag and a secondary update cycle. They’re now computed
properties reading directly from audioPlayer.currentTime and
audioPlayer.duration — updates arrive instantly via SwiftUI’s
observation, same as the full Now Playing view.
