steps to reproduce

  1. go to the gallery app
  2. edit the info.plist to use impeller
  3. open the ios/Runner.xcworkspace in xcode
  4. Make sure the "API Validation" checkbox is turned on for the configuration
  5. (not sure if this is necessary) run the project with the Release configuration
  6. Notice the crash at app startup.

notes

  1. Turning off "API Validation" removes the crash.
