xcode - BranchSDK 3.9.1 compilation failure: Branch.h file not found - Stack Overflow

Xcode is failing to compile the latest BranchSDK 3.9.1 included in the project from Cocoapods. Compilation fails to find the Branch.h header that does exist in Pods/BranchSDK/Sources/BranchSDK/Public/Branch.h

I was able to fix this by adding a kludge in my Xcode project file to add that as a user header search path, but this seems like the wrong solution:

"USER_HEADER_SEARCH_PATHS[arch=*]" = "Pods/BranchSDK/Sources/BranchSDK/Public/**";

What is the proper way to get Xcode to find this header for BranchSDK?

BranchSDK 3.9.1 (latest as of March 2025) Xcode 15.3 Cocoapods 1.15.2

Podfile:

source '.git'
source '/'
platform :ios, '12.0'
use_frameworks!
target 'Amtrak' do
    project 'Amtrak.xcodeproj'
    ...
    pod 'BranchSDK', '~> 3.9.1'
end

Here is the detailed error
