Migrate all remaining migratable .js/.mjs files to .ts with strong typing:
- constants/MediaTypes: as const + derived MediaType union
- utils/profiles/{download,subtitles,trackplayer}: typed against
@jellyfin/sdk DeviceProfile/SubtitleProfile/CodecProfile models;
native.ts now validates its profile with `satisfies DeviceProfile`
- trackplayer.d.ts removed (superseded by real TS implementation)
- index.js -> index.ts (entry point, "main" is extension-less)
- scripts/{typecheck,check-i18n-keys,detect-duplicate-issue} -> .ts,
all run via bun (typecheck switched from node to bun)
Remove scripts/symlink-native-dirs.js: dead since 446439c2 (2025-02-28)
when its only reference (prebuild:tv-new) was dropped; superseded by
`expo prebuild --clean` + cross-env EXPO_TV. Drop the matching
.gitignore relics (/iostv, /iosmobile, /androidmobile, /androidtv).
Document tooling-required .js exceptions (babel/metro/react-native/
tailwind configs) in CLAUDE.md and copilot-instructions.md so code
review guidelines stop flagging them.
Build #9 proved `-weak_framework SwiftUICore` does NOT bypass the allowed-client
check, and applying it to the tvOS app target regressed tvOS — reverted that
plugin (withSwiftUICoreWeakLink).
Confirmed root cause from build #8/#9 logs: both iOS jobs fail at the app
*executable* link (`Ld … Streamyfin`), not at any pod. SwiftUI was split into
SwiftUI + SwiftUICore on iOS 26; the SwiftUI pods emit a `-framework SwiftUICore`
autolink directive that, under use_frameworks :static, is inherited by the app's
static link, and the app isn't an allowed client of the private SwiftUICore.tbd.
Fix: in the pod post_install, compile pods with
`-Xfrontend -disable-autolink-framework -Xfrontend SwiftUICore` so they stop
emitting that direct autolink. SwiftUICore symbols then resolve through SwiftUI's
re-export (SwiftUI.tbd re-exports SwiftUICore). Scoped to phone
(ENV['EXPO_TV'] != '1') to leave the green tvOS build untouched.
Also harden scripts/ios/build-ios.ts: displayBuildError now surfaces the
"Undefined symbols for architecture …" linker block, which the error:-only
pattern filter was swallowing (so unsigned-build failures show the real symbol).
