Trouble integrating latest BraintreeDropIn pod to NativeScript app

App_Resources/iOS/Podfile と App_Resources/iOS/build.xcconfig を調査し、その後 BraintreeDropIn 9.1.0 を使用して iOS ビルドを再現し、動作する 8.x 構成および Braintree 5.4.2 のケースと比較します。新しい DropIn pod を使用して NativeScript iOS ビルドが完了し、メタデータ生成が成功すれば完了です。

I am trying to update the native dependencies within the nativescript-braintree plugin. While everything works as expected on Android side, I am struggling to make the ios build process working.

The migration guide says:

The Braintree iOS v5 SDK requires Xcode 12+, Swift 5.1+ and a minimum deployment target of iOS 12.0.
If your application contains Objective-C code, the Enable Modules build setting must be set to YES.

I am adding the following to App_Resources/iOS/Podfile:

platform :ios, '12.0'
pod 'BraintreeDropIn', '9.1.0'

And I am adding this to App_Resources/iOS/build.xcconfig:

IPHONEOS_DEPLOYMENT_TARGET = 12.0;
ENABLE_MODULES = YES;

When using version 8.x.y of the BraintreeDropIn pod, everything works as expected. Also when using the latest core pod of the Braintree SDK (Braintree pod version 5.4.2), the build process works as expected, so something is going wrong with the BraintreeDropIn particularly.

I cannot see any issues on Github so I think this is somehow related to NativeScript?

The build log looks like this (only snippets, the whole log file is provided below):
