iOS build error AppboyUI.ContentCards.bundle not found

[Personal-Group]

We're getting the following error when building with any version of the plugin (master or 2.21.0), though we're specifically using the geofence branch.

The following build commands failed:

This is happening with Xcode 12.4, Cocoapods 1.10.1.

This can be replicated with a bare-bones Cordova application:

cordova create BrazePluginTest
cd BrazePluginTest
cordova platform add ios
cordova plugin add https://github.com/Appboy/appboy-cordova-sdk.git#2.21.0
cordova build ios

Please let me know if you require any additional information.

It seems this issue is either due to Cocoapods or a Cordova build directory setting. I have implemented a temporary workaround to override using CONFIGURATION_BUILD_DIR in the build.js script as suggested in apache/cordova-ios#659.
