If you use @ionic-native/google-maps, please tell the package.json (only @ionic-native/core and @ionic-native/google-maps are fine mostly)

@ionic-native/core : 4.9.2
@ionic-native/google-maps : 4.8.2 

Current behavior:
After updating from 2.3.6 to 2.3.7 I cannot build for ios (building for android is working fine).

steps:

1. ionic cordova plugin rm cordova-plugin-googlemaps
2. ionic cordova plugin add cordova-plugin-googlemaps --variable ...
3. ionic cordova build ios

Expected behavior:
Successful build for ios

Likewise, it appears like the functions are defined in both files, but I think either file comes from different locations (CordovaGoogleMaps from the Google Maps SDK; the other from the plugin file, MyPluginLayer).

[antmr1]

Yes, you are right. Different files, but both from the googlemaps plugin...

[wf9a5m75]

Please share your project files that reproduce your issue 100% onto GitHub

[antmr1]

Sorry, that's not that simple as the project is a private one. I try to set up a test repository, otherwise I need to get the permission to request private support with committing to an NDA.

[wf9a5m75]

Without reproducible project, I won't do nothing.
Basically I don't change so much from v2.3.6 to v2.3.7
Double check your project, please

[wf9a5m75]

:scream:Uh, ah....

It seems I copied the code of MyPluginLayer.m into CordovaGoogleMaps.m...

[wf9a5m75]

v2.3.8 is available. Please reinstall the plugin.
https://www.npmjs.com/package/cordova-plugin-googlemaps/v/2.3.8

[kelvindart]

Thanks @wf9a5m75 - it's working well. Great work.
