I'm building a command line tool with the Swift Package Manager, using Ink as a dependency.
I'm following this article by John Sundell for reference, and I managed to get the tool to compile and run with swift build -c release.
I also generated a corresponding Xcode project with swift package generate-xcodeproj, so that I can use the debugger and work more effectively.
However, whenever I try to run my tool from Xcode, I get this error:
dyld: Library not loaded: /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/Ink.framework/Versions/A/Ink
Referenced from: /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/HIToolbox
Reason: Incompatible library version: HIToolbox requires version 1.0.0 or later, but Ink provides version 0.0.0
Program ended with exit code: 9
For reference, here's my Package.swift:
import PackageDescription
let package = Package(
name: "SwiftSiteGen",
dependencies: [
// Dependencies declare other packages that this package depends on.
// .package(url: /* package url */, from: "1.0.0"),
.package(
url: "https://github.com/johnsundell/files.git",
from: "4.0.0"
),
.package(
url: "https://github.com/johnsundell/Ink.git",
from: "0.1.3"
),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "SwiftSiteGen",
dependencies: ["SwiftSiteGenCore"]),
.target(name: "SwiftSiteGenCore",
dependencies: ["Files", "Ink"]),
.testTarget(
name: "SwiftSiteGenTests",
dependencies: ["SwiftSiteGen"]),
]
)
I'm running on Xcode 11.2.1, on macOS 10.14.4.
Since running swiftc build works, I feel that the problem is with Xcode trying to use dynamic frameworks rather than static libraries. Possibly related question here.
Are there some Xcode project settings I need to change to make this work?
Verified Solution
Do not run swift package generate-xcodeproj.
Instead, just open Package.swift directly in Xcode.
That way, all packages are statically linked.

I'm new with Swift and all this tools.
I've tried to look for guides but they didn't help me. I wanna try to work with packages in VS code.So I decided to add a SwiftyJSON package. This is my Package.swift file:
import PackageDescription
let package = Package(
name: "SwiftyJSON",
dependencies: [
.package(url: "https://github.com/SwiftyJSON/SwiftyJSON.git", from: "4.0.0"),
]
)
And I got an error
error: no such module 'PackageDescription' import PackageDescription
For VS Code I use an extension Swift and package dependencies.
It automatically detects a package but when I save my Package.swift file terminal gives me an error:
> Executing task: swift package resolve <
'swiftpackages': error: the manifest is missing a Swift tools version specification;
consider prepending to the manifest '// swift-tools-version: 5.6' to
specify the current Swift toolchain version as the lowest Swift version
supported by the project;
if such a specification already exists, consider moving it to the top
of the manifest, or prepending it with '//' to help Swift Package
Manager find it
The terminal process "/opt/homebrew/bin/zsh '-c', 'swift package
resolve'" failed to launch (exit code: 1).
How I can add packages in VS code?
I'm trying to build swift package with external dependency (CoreStore) with xCode11 beta 7. My package is targeted for iOS11+, it's declared in Package.swift:
// swift-tools-version:5.1
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "Storages",
platforms: [.iOS(.v11)],
products: [
// Products define the executables and libraries produced by a package, and make them visible to other packages.
.library(
name: "Storages",
targets: ["Storages"]),
],
dependencies: [
// Dependencies declare other packages that this package depends on.
.package(url: "https://github.com/JohnEstropia/CoreStore.git", from: "6.3.0")
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "Storages",
dependencies: [.product(name: "CoreStore")]),
.testTarget(
name: "StoragesTests",
dependencies: ["Storages"]),
]
)
However, when I build it dependency builds without iOS version specified, so I get compatibility errors:
"'uniquenessConstraints' is only available in iOS 9.0 or newer" and so on.
How can I fix it? Looks like it's xCode11 bug, but I'm not sure.
On my machine, adding the platforms: parameter to the manifest solved it. For example:
let package = Package(
name: "MyLibrary",
platforms: [.iOS("13.0")],
// ...
I'm not sure is it xCode bug or not, however with Swift Package Manager and xCode 11 you have to clearly specify iOS version when use #available check. Not matter if library is targeted for iOS 10+ or not, instead of
if #available(macOS 10.11, *) {
info.append(("uniquenessConstraints", self.uniquenessConstraints))
}
you should use
if #available(macOS 10.11, iOS 9.0, *) {
info.append(("uniquenessConstraints", self.uniquenessConstraints))
}

First, you need to add a platform parameter and fill it out with the supported platform versions. Then, you need to clear derived data in your host app. After that, try adding the spm framework again.
I had the same thing where I didn't add the platform parameter at first and it was giving me so many "'xxx' is only available in iOS 9.0 or newer" errors in my host app. Hopefully that fixes it for you.
I'm using Swift Package Manager to create a macOS executable. When I use things that aren't available in all macOS versions I get compile errors. Two big examples are URL(fileURLWithPath: filePath, relativeTo: directoryToSearch) and url.hasDirectoryPath.
When building with swift build I get error: 'init(fileURLWithPath:relativeTo:)' is only available on OS X 10.11 or newer errors. I don't care about any old OS versions, as it's just a personal tool. How can I set the deployment target to be 10.14 so I don't have to sprinkle checks all through out my code?
I found https://hirschmann.io/swift-package-manager/ which talks about this issue. However it's solution is creating an xcconfig file with the deployment target set and using swift package generate-xcodeproj --xcconfig-overrides ./main.xcconfig to apply it to the generated Xcode project. While it does work, it only works for the Xcode project, so if I just want to do swift build to get the free standing executable to use outside of Xcode then I can't.
My package file was auto generated by swift package init --type executable and hasn't been changed.
// swift-tools-version:4.2
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "swift_converter",
dependencies: [
// Dependencies declare other packages that this package depends on.
// .package(url: /* package url */, from: "1.0.0"),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "swift_converter",
dependencies: []),
.testTarget(
name: "swift_converterTests",
dependencies: ["swift_converter"]),
]

This may not help you right now, but the upcoming Swift 5.0 will include the ability to specify the deployment target in the package manifest, using a syntax like this:
...
platforms: [
.macOS(.v10_13), .iOS(.v12),
],
...
(The same is true for some other common build settings.)
Until then, you can override the default deployment target via command line arguments like this:
$ swift build -Xswiftc "-target" -Xswiftc "x86_64-apple-macosx10.14"
You'll have to include these arguments in every call to swift build, swift run, swift test.
I'm encountering an issue creating a Swift Package for my project. I have CocoaPods and Travis CI running and both are working swimmingly, however I now intend to also offer the project through the Swift Package Manager. This is where I'm running into issues. My package file is looking like the following:
// swift-tools-version:4.2
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "Voxosonus",
products: [
// Products define the executables and libraries produced by a package, and make them visible to other packages.
.library(
name: "Voxosonus",
targets: ["Voxosonus"]),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "Voxosonus",
path: "Voxosonus"),
.testTarget(
name: "VoxosonusTests",
dependencies: ["Voxosonus"],
path: "VoxosonusTests"),
]
)
However when I run swift build I encounter the following:
/Users/<hidden>/Documents/Projecten/Voxosonus/Voxosonus/SpeechRecognizer.swift:8:8: error: no such module 'Speech'
import Speech
My question is - why is it unable to find the 'Speech' module? This is core functionality from Apple themselves and so far the internet has made me none the wiser. Some details on the project:
Build target: iOS 12.x
macOS: 10.14
Swift Version: 4.2.1
As explained in the Swift Package Manager Github, you can't define the target platform of a Swift Package yet:
At this time there is no explicit support for depending on UIKit,
AppKit, etc, though importing these modules should work if they are
present in the proper system location. We will add explicit support
for system dependencies in the future. Note that at this time the
Package Manager has no support for iOS, watchOS, or tvOS platforms.
So when you are try to build the library with Xcode (or with the swift build command), the compiler can't find the Speech module because it is only available on iOS 10+.
You can check this github project (swift-package-manager-ios) which provides a ruby script that modify the xcodeproj generated by the Swift Package Manager by adding the necessary information in order to build for the iOS platform.
Example:
> mkdir myProject && cd myProject
> swift package init --type executable
Edit Package.swift (added 1 dependency):
// swift-tools-version:4.0
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "myProject",
dependencies: [
// Dependencies declare other packages that this package depends on.
// .package(url: /* package url */, from: "1.0.0"),
.package(url: "https://github.com/someone/myProject.git", from: "1.0.0"),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages which this package depends on.
.target(
name: "myProject",
dependencies: []),
]
)
