feat(ios): runtime .pulsar bundle loader + SwiftPM plugin (2/6) - #203
Merged
Conversation
Foundation for custom preset bundles. Defines the .pulsar format (ZIP + manifest.json), a JSON schema, and pulsar-gen: a zero-dependency Node/TS CLI that reads a .pulsar and emits typed accessors for swift/kotlin/dart and an RN JSON sidecar (keyof-inference, nano-icons style). Includes a fixture bundle, golden outputs, and a node:test suite (7 passing). Portable emitter core is reusable from Studio's browser exporter.
Adds runtime bundle loading to the standalone iOS SDK (PulsarHaptics), the artifact RN + Flutter link against: - Bundle/PulsarUnzip.swift: minimal STORE+DEFLATE zip reader over the Compression framework (no new dependency). - Bundle/PulsarBundle.swift: Codable manifest, PresetHandle (lazy parse, synced audio via parsePatternWithSound, animation bytes for the app to render), LoadedBundle (untyped string-keyed surface for the RN/Flutter bridges), and the typed PulsarBundle<P>/BundleDescriptor<P>/BundleResolver. - Bundle/BundleLoader.swift: Pulsar.loadBundle(data:/path:) + typed loadBundle(_:strict:); haptics JSON decodes straight into PatternData; audio extracted to caches for Core Haptics. - pulsar-gen-swift host tool + PulsarGenPlugin build-tool plugin: regenerate the typed accessor on every build, no Node/network in the sandbox. - BundleTests: unzip + load + typed-view + schema-rejection (Swift Testing). The loaded bundle owns its handles, so no change to the compiled preset registry. Note: native/plugin code is not compiled in this environment (iOS/UIKit); verify via xcodebuild on a simulator.

Runtime bundle loading in the standalone iOS SDK (
PulsarHaptics, the pod RN + Flutter link against).Bundle/PulsarUnzip.swift— minimal STORE+DEFLATE zip reader over theCompressionframework (no new dependency).Bundle/PulsarBundle.swift— Codable manifest;PresetHandle(lazy parse, synced audio viaparsePatternWithSound, animation bytes exposed for the app to render);LoadedBundle(untyped string-keyed surface for the RN/Flutter bridges); typedPulsarBundle<P>/BundleDescriptor<P>/BundleResolver.Bundle/BundleLoader.swift—Pulsar.loadBundle(data:/path:)+ typedloadBundle(_:strict:). Haptics JSON decodes straight into the existingPatternData; audio extracted to caches for Core Haptics.pulsar-gen-swifthost tool +PulsarGenPluginbuild-tool plugin — regenerate the typed accessor on every build, no Node in the sandbox.BundleTests(Swift Testing): unzip + load + typed-view + schema rejection.The loaded bundle owns its handles, so the compiled preset registry is untouched.
Verification
