[Bug] iOS build broken due to compiler errors in MMKVCore

[trcoffman]

Describe the bug
iOS builds suddenly started failing because of upstream publishing of new MMKV and MMKVCore to cocoapods.

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/trcoffman/mmkv-build-issue
2. Try to build it with npm run ios

Expected behavior
The app compiles

If you use expo with CNG, you can work around it like this:

In the plugins section of your app.config.js use expo-build-properties to pin MMKV and MMKVCore pods:

    [
      'expo-build-properties',
      {
        ios: {
          extraPods: [
            {
              name: 'MMKV',
              version: '1.3.9',
            },
            {
              name: 'MMKVCore',
              version: '1.3.9',
            },
          ],
        },
      },
    ],

If you use a bare RN workflow, put this in your Podfile.

pod 'MMKV', '1.3.9'
pod 'MMKVCore', '1.3.9'

pod 'MMKV', '1.3.9'
pod 'MMKVCore', '1.3.9'

same issue. is the only solution downgrading?

Same thing also happen in MMKV_iOS flutter plugin. I think it has something to do with the MMKV pod / MMKVCore pod

[heritvithalani19]

Xcode: 16.2
mmkv: "react-native-mmkv-storage": "0.10.2",
RN version: 0.71.19

The same issue also occurs with the MMKV_iOS React Native plugin. I believe it might be related to the MMKV pod or the MMKVCore pod.
