Hello,
In Xcode 15 beta 3, if a project embedded a Swift package (no matter static or dynamic), and the package has its own dependencies, the linker will always emit following warning:
ld: warning: duplicate -rpath '/Users/.../Library/Developer/Xcode/DerivedData/MyApp.../Build/Products/Debug-iphonesimulator/PackageFrameworks' ignored
The warning is not appeared on beta 2 and beta 1.
Reproduce Steps
- [1] Create a new iOS project in Xcode 15 beta 3
- [2] Create a new Swift package
MyLibrary
, and add any dependency in thePackage.swift
. Example:
// swift-tools-version: 5.9
import PackageDescription
let package = Package(
name: "MyLibrary",
platforms: [.iOS(.v16)],
products: [
.library(name: "MyLibrary", targets: ["MyLibrary"]),
],
dependencies: [
// 👀 Add any dependency to this package.
// Here I use "Version" which is a simple pure swift package:
.package(url: "https://github.com/mxcl/Version.git", .upToNextMajor(from: "2.0.0")),
],
targets: [
.target(name: "MyLibrary", dependencies: ["Version",]),
]
)
- [3] In the project page, embed
MyLibrary
into the iOS app target. - [4] Build the project. It will succeed but with link warnings.
In addition, if you create a dynamic framework and embed MyLibrary
, the warnings also reproduce. And this is only a simple case. In my real project, the linker will also emit a lot of warnings like this:
