fix(ios): make podspec helpers visible inside the spec block

[jkasprzyk17]

What does this change?

Every pod install of the package has been broken since #51. That PR added two top-level def helpers to react-native-better-maps.podspec to read betterMaps.iosGoogleProvider from Podfile.properties.json. CocoaPods loads a podspec with eval inside Pod._eval_podspec, so a def in the file becomes an instance method of the Pod module. Inside the Pod::Spec.new block self is that module, so the call fails on every Ruby and CocoaPods version:

[!] Invalid `react-native-better-maps.podspec` file: undefined method 'better_maps_ios_google_provider_enabled?' for module Pod.

(add_nitrogen_files is unaffected because it arrives through load, which defines methods on Object.)

Three changes, all in the podspec:

1. The helpers become local lambdas. This is the podspec hunk from perf: update overlays in place, coalesce marker refreshes, fix quadratic clustering #67.
2. rescue StandardError inside the helper resolved to Pod::StandardError for the same lexical-scope reason (cocoapods-core defines that class), so it never caught JSON::ParserError and a malformed Podfile.properties.json still broke pod install. It is now rescue ::StandardError.
3. Valid JSON that is not an object (null, an array, a scalar) raised on the key lookup. It is now treated as no properties, with a warning. (CodeRabbit finding.)

Because of 2 and 3 the file is no longer byte-identical to #67, so #67 will get a small conflict in this file on rebase; take main's version.

Without this, a 1.2.0 cut from main cannot be installed in any iOS project.

How was it verified?

Host: CocoaPods 1.17.0 with Ruby 4.0.6; the original failure also reproduces with the system Ruby 2.6.10.

• pod ipc spec package/react-native-better-maps.podspec on main fails with the error above. On this branch the helper evaluates and the command only stops at install_modules_dependencies, the React Native Podfile helper that does not exist outside a real pod install.
• A Ruby harness that loads the file the way pod install does (Pod::Specification.from_file, with install_modules_dependencies stubbed) and swaps Podfile.properties.json between seven states: absent, "true", "false", null, [], 42, malformed. On main every state fails. With only the lambda rewrite, null, [], 42 and malformed still fail. On this branch all seven load; GoogleMaps is a dependency only for "true", and the non-object and malformed cases record the warning.
• End to end in example/: expo prebuild --platform ios --no-install, then pod install completes (93 dependencies, 92 pods) with react-native-better-maps (1.1.0) in Podfile.lock and no GoogleMaps, because no API key was configured.
• ruby -c on the system Ruby 2.6.10 parses the file.

Not run: xcodebuild. No Swift or generated sources change, only the podspec DSL.

Scope

• Providers: both (the flag only decides whether the Google Maps SDK is linked)
• Platforms: iOS

Checklist

• bun run lint, bun run typecheck and bun run build pass
• Tests pass, and new behavior is covered by a test (163 tests; no JS test can cover a podspec, see note below)
• Nitro specs changed? bun run nitrogen was re-run and the generated code is committed (not changed)
• Public API changed? The README and the capability matrix are updated (not changed)
• Commits follow Conventional Commits
• Behavior changed without a type change? Say so explicitly above — it breaks consumers whose code still compiles (no consumer-visible change beyond pod install working again)

CI never evaluates the podspec, which is how #51 landed green. A macOS-free check is possible (gem install cocoapods plus a script that calls Pod::Specification.from_file with the RN helper stubbed); worth a separate PR.

📝 Summary

Summary by CodeRabbit

• Chores
  • Improved iOS configuration handling for Google Maps provider settings.
  • Invalid or unexpected configuration values are handled more safely, with warnings where appropriate.
  • No user-facing feature or public API changes.

Walkthrough

The podspec replaces top-level helper methods with local lambdas and a provider-enabled boolean. Property parsing now rejects non-object JSON values with a warning. The GoogleMaps dependency condition uses the boolean.

Changes

Podspec Provider Configuration

Layer / File(s)	Summary
Local provider resolution package/react-native-better-maps.podspec	Property loading and provider detection use local lambdas and a boolean. Null, array, and scalar JSON values produce a warning and return {}. Read and parse errors retain warning handling. The GoogleMaps dependency condition uses the boolean.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to df1f5

The podspec preserves expected provider configuration behavior and handles invalid property files without blocking installation.
