I want to create a Swift Package with binary targets which has sub dependencies. As the binary targets not support sub dependencies out of the box, I have created a wrapper target that depends on both the binary framework and other dependencies as described here
Package has a target called Logger.
CocoaLumberjack is a dependency of Logger.
Logger I have generated as XCFramwork and hosted in a server as publicly accessible. Below I have added a screenshot of the Xcode project which I used to generate XCFramwork.
Please refer to the Package manifest file.
import PackageDescription
let package = Package(
name: "spmpoc",
products: [
.library(
name: "Logger",
targets: ["LoggerTarget"]),
],
dependencies: [
.package(
name: "CocoaLumberjack",
url: "https://github.com/CocoaLumberjack/CocoaLumberjack.git",
from: "3.6.1"),
],
targets: [
.target(
name: "LoggerTarget",
dependencies: [.target(name: "LoggerWrapper",
condition: .when(platforms: [.iOS]))]
),
.target(
name: "LoggerWrapper",
dependencies: [
.target(name: "Logger", condition: .when(platforms: [.iOS])),
.product(name: "CocoaLumberjack", package: "CocoaLumberjack")
]
),
.binaryTarget(name: "Logger", url: "https://mypath.com/Logger.xcframework.zip", checksum: "mychecksum")
]
)
I am able to add Swift package via Swift Package Manager, but When I try to import Logger module build error occured as ..../Logger.framework/Modules/Logger.swiftmodule/arm64-apple-ios.swiftinterface:4:8: No such module 'CocoaLumberjack'
Could someone please help me to figure out what could be the issue here?
Error
XCFramwork code snapshot for reference
Update:
I have change import to @_implementationOnly import in Logger.swift. Now in the generated .swiftinterface files does not contains the "import CocoaLumberjack" hence, compile error went away. However, app crashing because it is still looking for CocoaLumberjack.framework but its not available. '.../Library/Developer/Xcode/DerivedData/TestSPMApp-gfbagjtzjrrkjuathrrienvklwxs/Build/Products/Debug-iphonesimulator/CocoaLumberjack.framework/CocoaLumberjack' (no such file)
CocoaLumberJack added to Logger framework as a pod dependency. It seems, inside the Pods-Logger.xcconfig file it is referring to CocoaLumberjack.framework. I believe this causes the issue now.
