Note

Medium Risk
Moderate risk because it upgrades a native iOS SDK dependency, which can introduce behavioral or API changes at build/runtime despite minimal code changes here.

Overview
Updates the iOS podspec to depend on Helium 4.3.0 (from 3.1.6).

Bumps the library version in package.json from 3.0.23 to 3.0.24 to publish the dependency update.

Major dependency bump masked as patch version update

Medium Severity

The native Helium CocoaPods dependency jumps from 3.1.6 to 4.3.0 (a major version change), but the npm package version only gets a patch increment (3.0.23 → 3.0.24). Consumers using semver ranges like ^3.0.23 will automatically receive this update, which bundles a major native SDK version change. This violates semver expectations — a major dependency upgrade can introduce behavioral changes, even if the wrapper's Swift bridge API remains source-compatible.
