Summary

Improve iOS simulator screenshot stability by reopening Simulator around screenshot attempts and centralizing retry policy constants in iOS config.
Add a unit test that verifies simulator screenshot retries on transient screen-surface timeout failures.

  • node --test src/platforms/ios/tests/index.test.ts
