When using the static library built by spm, Xcode reports an error: Duplicate symbols

[tamwei]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

When a static library(framework) with a dependency was built in app, Xcode report an error: duplicate symbol

Expected behavior

The above swift static library can be used normally

Actual behavior

Xcode report an error: duplicate symbol

Steps to reproduce

Step:

1. I created a static library(framework) with a dependency by spm.
2. Then when I buld an app with the static library, Xcode reports an error: duplicate symbols

---

The following cases were tested:

1. Using either the Alamofire dependency or the Firebase dependency alone in Xcode will result in compilation errors.
2. No error will be reported when compiling the app under Objective-C, but an error will be reported when compiling the app under Swift.

Xcode report an error: duplicate symbol

This contradicts the question above whether this was reproducible from the SwiftPM CLI.
