I already have a working Xcode project for a MacOS App. However, I would like to add a Swift framework from Github using Swift Package Manager.

I ran "swift package init" inside the project folder. Then I updated Package.swift file. Then I ran "swift package resolve".

However, it still complains no such module when I try to build.

Since I already have a working project, if I run "swift package generate-xcodeproj", it messes up the folder structure as well as removing the storyboard.

How can I tell Xcode to use the module that swift package manager downloaded into the project?

Thank you!

macOS, iOS, tvOS, and watchOS do not support the Swift Package Manger at the time of this writing (Dec 2017). Instead, you will have to add the files from the package directly to your project.

I would suggest creating a Dependencies group in your project and a group below that with the package name:

Then add the files to the group:

I was unable to get this to work if I added folders, so you should add all the files to groups if you want to maintain structure of the package. I might have done this the wrong way though.

You can then access the code as you usually would when you write it yourself. No imports.

Steps to achieve Swift Package Manager and XCode integration in 2019:

1) Create Dependencies.swift file
/yourproject/Dependencies/Sources/Dependencies.swift

(empty file)

2) Create macos.xcconfig file
/yourproject/Dependencies/Sources/macos.xcconfig

MACOSX_DEPLOYMENT_TARGET = 10.14

3) Create Package.swift file
/yourproject/Dependencies/Package.swift

// swift-tools-version:4.2
import PackageDescription

let package = Package(
 name: "Dependencies",
 products: [
 .library(name: "Dependencies", type: .static, targets: ["Dependencies"])
 ],
 dependencies: [
 .package(url: "https://github.com/YourDependency/here.git", .upToNextMinor(from: "0.1.0"))
 ],
 targets: [
 .target(name: "Dependencies", dependencies: ["YourDependency"])
 ]
)

4) Generate Dependencies.xcodeproj and drag-and-drop into your existing project

swift package generate-xcodeproj --xcconfig-overrides Sources/macos.xcconfig

5) Import your dependency

import YourDependency

This is enough to make it work but you can make your life a bit easier with a few extra steps.

Additional (optional) steps:

6) Create ios.xcconfig file
/yourproject/Dependencies/Sources/ios.xcconfig

SDKROOT = iphoneos
SUPPORTED_PLATFORMS = iphonesimulator iphoneos
IPHONEOS_DEPLOYMENT_TARGET = 10.0

ARCHS = $(ARCHS_STANDARD)
VALID_ARCHS = $(ARCHS_STANDARD)

VALIDATE_PRODUCT = YES
LD_RUNPATH_SEARCH_PATHS = $(inherited) @executable_path/Frameworks
TARGETED_DEVICE_FAMILY = 1, 2

7) Add Pre-build action to your main project's iOS and macOS Schemes

iOS

echo "Building SPM Dependencies"
BASE_DIR="$PROJECT_DIR/Dependencies"
cd $BASE_DIR

rm -fr Dependencies.xcodeproj
swift package update
swift package generate-xcodeproj --xcconfig-overrides Sources/ios.xcconfig

sleep 3

until [ -d "Dependencies.xcodeproj" ]
do
echo "File not found"
sleep 0.1
done
echo "File found"
exit

macOS

echo "Building SPM Dependencies"
BASE_DIR="$PROJECT_DIR/Dependencies"
cd $BASE_DIR

rm -fr Dependencies.xcodeproj
swift package update
swift package generate-xcodeproj --xcconfig-overrides Sources/macos.xcconfig

sleep 3

until [ -d "Dependencies.xcodeproj" ]
do
echo "File not found"
sleep 0.1
done
echo "File found"
exit

8) Run your project and enjoy :)

The generated Xcode project from SPM is different from your app's Xcode project/workspace.

You should generate that Xcode project in another directory eg. "Dependencies".

Then drag it into your app's, and add the linked framework. I have written a full step-by-step.
