Can't build because warning "'temporaryDirectory' is only available in macOS 10.12 or newer"

about

• Can't build because warning 'temporaryDirectory' is only available in macOS 10.12 or newer at line 556 of CommandLine.swift.
• It may have something to do with 573ae3f.
• If version 0.49.4 is specified in a similar environment, the build succeeds.

environment

• SwiftFormat 0.49.6
• macOS 12.3
• Xcode13.3
• iOS App project (target iOS 15.0 or newer)
• use SPM.（I have introduced this guideline.）

// swift-tools-version:5.6
import PackageDescription

let package = Package(
    name: "BuildTools",
    platforms: [.macOS(.v10_12)],
    dependencies: [
        .package(url: "https://github.com/nicklockwood/SwiftFormat", from: "0.49.0"),
    ],
    targets: [.target(name: "BuildTools", path: "")]
)

@dazy1030 fixed in 0.49.7

Hi,

I almost have the same issue on both 0.49.7 & 0.49.18:

'temporaryDirectory' is only available in iOS 10.0 or newer

I have tried to clean the project, remove derived data and reset package caches but nothing helped.
Do you have any suggestion to fix that?
Please let me know if I can provide any further information.

Thank you in advance

Environment

• macOS 12.5.1
• Xcode 13.4.1
• iOS App project (target iOS 14.3 or newer)
• use SPM

I have same issue as @bilalb. Checked with 0.49.7 & 0.49.18
On 0.49.4 I have this issue: #424
I've added SwiftFormat through Package Dependencies on iOS Project in Xcode 13.4.1.
My idea was to use SwiftFormat as Swift Package plugin (https://developer.apple.com/videos/play/wwdc2022/110359/)
@nicklockwood any ideas? ;)

I'm not exactly clear how you can correct it, but it seems like the way you've integrated SwiftFormat means it's trying to build it for iOS, which isn't right.

Even if you are planning to format an iOS project, the SwiftFormat plugin should be built for macOS, in which case the iOS version you are targeting shouldn't matter?

[bilalb]

I've just realised SwiftFormat should not be added to the project's package dependencies 😅
So I've removed it and now everything works as expected 🎉

Thanks your feedback and keep up the great work!

@bilalb If not added as project's package dependencie - then how to add it through SPM?

[bilalb]

It should not be added via SPM, as described in Xcode build phase > Using Swift Package Manager
