[divineniiquaye]

I encountered this issue on my MacOS Sequoia 15.0 (Beta) with new architect enabled react native expo 51.0.31

Guten Tag, Hans here! 🥨🍻

Thanks for reporting ze issue. It looks like you have a compilation problem related to MMKVConfig and MmkvCxxMode. However, I see that you are using a beta version of macOS and a new architect of React Native, which could lead to compatibility issues.

Could you please provide more details about your setup? Specifically, we need to know the versions of React Native and other libraries you are using, as well as output from the Xcode build logs showing any additional context on ze errors. This information can help mrousavy track down ze issue more effectively.

If you're finding this repository useful, consider sponsoring mrousavy to help keep ze project alive: Sponsor mrousavy.

Note: If you think I made a mistake, please ping @mrousavy to take a look.

I was able to resolve the issue by using the patch Originally posted by @davebray131 in https://github.com/mrousavy/react-native-mmkv/issues/718#issuecomment-2295330525.

Just rename the patch file to react-native-mmkv+3.0.1.patch

I am working on a fix and will release it soon - in the meantime you can sponsor me on GitHub to buy me a coffee or say "thanks". 😃❤️

released in react-native-mmkv 3.0.2 :rocket:

Still facing the same issue. With version 3.0.1 and 3.0.2 both

Everything is working fine. Just make sure that react-native is on version 0.75.x. I used the new architecture on version 0.74 but it didn’t work, so I had to upgrade to 0.75

react-native: "0.75.2" expo: "51.0.32" mmkv: "3.0.2"

still the same issue during the building process on IOS

+1 with 0 details helps no one, See here where I outline a number of things about the combination of libs and migrating between versions https://github.com/mrousavy/react-native-mmkv/issues/731#issuecomment-2339487315

[batcodegen]

for me updating my mac and xcode to latest update fixed the issue automatically. Also had to follow the steps https://github.com/reactwg/react-native-new-architecture/blob/main/docs/enable-apps.md specifically https://github.com/reactwg/react-native-new-architecture/blob/main/docs/enable-apps.md#troubleshooting

I was also facing the same issue with my iOS build and after having a look at NativeMmkvModule.h I noticed some definitions missing. I updated the file and the build worked fine. Here is the patch file react-native-mmkv+3.0.2.patch

[oscadev]

"add new architecture" : nah "use this patch!": nah

Just use v2.12.2 and it works.
