Could you build this?
No A high-performance, low-latency PDF annotation engine with 60/120fps Apple Pencil stroke rendering, vector layers, and synchronized audio playback requires deep native graphics programming.
What it would actually take: This requires native Swift/SwiftUI and Metal or Core Graphics to implement a custom low-latency drawing pipeline that handles stroke coalescing, smoothing algorithms (Catmull-Rom splines), and memory management over massive multi-page PDFs. The hardest parts are rendering stroke-heavy documents without thermal throttling/battery drain, multi-layer vector compositing, and time-indexing audio buffers directly to discrete vector stroke timestamps.
