[Bug]: Swift Package does not obey BYPASS_PERMISSION_LOCATION_ALWAYS setting

[pento]

Please check the following before submitting a new issue.

• I have searched the existing issues.
• I have carefully read the documentation and verified I have added the required platform specific configuration.

Please select affected platform(s)

• Android
• iOS
• Linux
• macOS
• Web
• Windows

Steps to reproduce

1. flutter create --platforms=ios geolocator_package_bug
2. Set your pubspec.yaml to enable swift package manager:

flutter:
  config:
    enable-swift-package-manager: true

3. Add geolocator to your dependencies, along with a package that still uses Pods (eg, flutter_keyboard_visibility), to force the Podfile to be created.
4. To generate the initial Podfile: flutter build ios --release
5. Add the config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', 'BYPASS_PERMISSION_LOCATION_ALWAYS=1'] section to the Podfile, as defined in the README.
6. flutter clean && flutter build ios --release
7. strings build/ios/iphoneos/Runner.app/Runner | grep -c "requestAlwaysAuthorization"

Expected results

% strings build/ios/iphoneos/Runner.app/Runner | grep -c "requestAlwaysAuthorization"
0

Actual results

% strings build/ios/iphoneos/Runner.app/Runner | grep -c "requestAlwaysAuthorization"
1

I was able to fix it in a local fork of geolocator_apple, by modifying geolocator_apple/darwin/geolocator_apple/Package.swift like so:

// swift-tools-version: 5.9
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "geolocator_apple",
    platforms: [
        .iOS("11.0"),
        .macOS("10.11")
    ],
    products: [
        .library(name: "geolocator-apple", targets: ["geolocator_apple"])
    ],
    dependencies: [],
    targets: [
        .target(
            name: "geolocator_apple",
            dependencies: [],
            resources: [
                .process("PrivacyInfo.xcprivacy")
            ],
            publicHeadersPath: "include/geolocator_apple",
            cSettings: [
                .headerSearchPath("include/geolocator_apple"),
                // Disable "Always" location permission - only use "When In Use"
                .define("BYPASS_PERMISSION_LOCATION_ALWAYS", to: "1")
            ]
        )
    ]
)
