pod install fails with undefined method post_install for nil

[antonsthb]

Hi,

I've been trying to install MapLibre in my app, but I cannot get it to work. Is there something I'm missing here? I've been following the installation guides for both iOS and android. Seems like the native MapLibre module is not being installed.

Steps to Trigger Behavior

1. Create new React Native project: npx @react-native-community/cli@latest init MapLibreTest --version 0.74.6
2. install MapLibre: npm install @maplibre/maplibre-react-native --save
3. Follow iOS Instructions (i.e. add line $MLRN.post_install(installer) in Podfile and run pod install)

Expected Behavior

Pods should install.

Actual Behavior

I get the following error during pod install:

Additional context

[KiwiKilian]

Could you please try with the latest beta pre-release? If it still doesn't work, please create a reproduction repository.

[antonsthb]

@KiwiKilian Thanks for your response, sorry, I forgot to fill in the latest version, I just updated the issue and added a repository containing a minimal reproducible example.

[KiwiKilian]

In your repository you are using $RNML instead of $MLRN in the Podfile.

[antonsthb]

Huh, no idea how I messed that up, it works now, thanks for the quick response! I'll close this as completed.
