SwiftUI Preview 错误地尝试从另一个平台构建条件依赖
当导入的 Swift 包之一对另一个平台有条件依赖时，SwiftUI 预览对我来说就被破坏了。
重现步骤：
- 创建具有 2 个目标的 Xcode 项目。一个用于 macOS，另一个用于 iOS。
- 添加具有条件依赖项的 Swift 包 - 例如。依赖于另一个包，但仅依赖于 iOS。 示例：
targets: [
.target(name: "Components",
dependencies: [
.productItem(name: "FloatingPanel", package: "FloatingPanel", condition: .when(platforms: [.iOS])),
]),
]
- 尝试在 macOS 上运行 SwiftUI 预览。这是行不通的。
我得到的错误是no such module UIKit。 看起来 Xcode 正在尝试构建 FloatingPanel 依赖项，即使它的条件指定了 iOS 平台。
有什么办法可以解决这个问题吗？
SwiftUI Previews are broken for me when one of imported Swift Package has a conditional dependency to another platform.
Steps to reproduce:
- Create Xcode Project with 2 targets. One for macOS, another for iOS.
- Add a Swift Package that has a conditional dependency - eg. depends on another package but only on iOS.
Example:
targets: [
.target(name: "Components",
dependencies: [
.productItem(name: "FloatingPanel", package: "FloatingPanel", condition: .when(platforms: [.iOS])),
]),
]
- Try running SwiftUI preview on macOS. It won’t work.
The error I get is no such module UIKit.
It looks like Xcode is trying to build FloatingPanel dependency even though it's condition specifies iOS platform.
Is there any way to fix this?

是的，我有同样的问题。
在为 iOS 构建时，条件适用于其他平台，但在为其他平台构建时，也始终包含 iOS 依赖项...
在 swift 论坛上发帖：

并且报告了几个错误...
Yes, I have the very same issue.
Condition works for other platform when building for iOS, but when building for other platrfom iOS dependencies are always included too...
