Optimizing integrations with the Mapbox Navigation SDK
summary
Delivery Hero integrates the Mapbox iOS Navigation SDK into its rider app, uses Xcode profiling and Sentry telemetry, and sees hangs spike — from moderate to ~37k then ~50k per day after rollout. Root cause is repeated recreation of navigation views (about once per second) combined with UIAppearance stylesheet accumulation so styles pile up in memory and view creation eventually takes ~0.5s, causing UI hangs. Resolution: profile SDKs, collect telemetry, use beta channels, file issues, and limit repeated styling and view recreation.
