Not possible to use Scipio to build some of the popular frameworks

[mikeger]

Hey 👋

I've tried to use Scipio for my project, but I've found a couple of issues.
The following frameworks cannot be compiled:

SDWebImage

Compilation error

The following build commands failed:
	CompileC /Users/m.gerasymenko/Library/Developer/Xcode/DerivedData/RiderAppDependencies-hemauyjxyusqbydjtqogvbdpzofn/Build/Intermediates.noindex/ArchiveIntermediates/SDWebImageMapKit/IntermediateBuildFilesPath/RiderAppDependencies.build/Release-iphoneos/SDWebImage.build/Objects-normal/arm64/UIColor+SDHexString.o /Users/m.gerasymenko/Projects/logistics-rider-app-ios/.build/checkouts/SDWebImage/SDWebImage/Private/UIColor+SDHexString.m normal arm64 objective-c com.apple.compilers.llvm.clang.1_0.compiler (in target 'SDWebImage' from project 'RiderAppDependencies')

GoogleTagManager

Compilation error

The following build commands failed:
	CompileC /Users/m.gerasymenko/Library/Developer/Xcode/DerivedData/RiderAppDependencies-hemauyjxyusqbydjtqogvbdpzofn/Build/Intermediates.noindex/ArchiveIntermediates/GoogleTagManagerTarget/IntermediateBuildFilesPath/RiderAppDependencies.build/Release-iphoneos/GoogleUtilities-NSData.build/Objects-normal/arm64/GULNSData+zlib.o /Users/m.gerasymenko/Projects/logistics-rider-app-ios/.build/checkouts/GoogleUtilities/GoogleUtilities/NSData+zlib/GULNSData+zlib.m normal arm64 objective-c com.apple.compilers.llvm.clang.1_0.compiler (in target 'GoogleUtilities_NSData' from project 'RiderAppDependencies')
(1 failure)

Firebase

Seems that one of the sub-dependencies are not automatically linked.

xcodebuild: error: The project named "RiderAppDependencies" does not contain a scheme named "FirebaseStorageSwift". The "-list" option can be used to find the names of the schemes in the project.

Example Package.swift

// swift-tools-version:5.6

import PackageDescription

let package = Package(
    name: "RiderAppDependencies",
    platforms: [
        .iOS(.v11),
    ],
    products: [],
    dependencies: [
        .package(url: "https://github.com/firebase/firebase-ios-sdk.git", exact: "8.15.0"),
        .package(url: "https://github.com/googleanalytics/google-tag-manager-ios-sdk.git", exact: "7.4.1"),
        .package(url: "https://github.com/vadymmarkov/Fakery", exact: "5.1.0"),
        .package(url: "https://github.com/SDWebImage/SDWebImage.git", exact: "5.8.2")
    ],
    targets: [
        .target(
            name: "RiderAppDependencies",
            dependencies: [
                .productItem(name: "FirebaseRemoteConfig", package: "firebase-ios-sdk"),
                .productItem(name: "FirebasePerformance", package: "firebase-ios-sdk"),
                .productItem(name: "FirebaseAnalytics", package: "firebase-ios-sdk"),
                .productItem(name: "FirebaseCrashlytics", package: "firebase-ios-sdk"),

                .productItem(name: "GoogleTagManager", package: "google-tag-manager-ios-sdk"),
                .productItem(name: "Fakery", package: "Fakery"),
                .productItem(name: "SDWebImage", package: "SDWebImage"),
                .productItem(name: "SDWebImageMapKit", package: "SDWebImage")
            ])
    ]
)

SDWebImage uses cSettings on Package.swift. Scipio can't treat this declaration correctly.
I'm going to fix this.

I'm unable to build Firebase either. There is a third-party Package manifest that includes pre-built xcframework files though: https://github.com/akaffenberger/firebase-ios-sdk-xcframeworks

There is an in-depth discussion about this repo here: firebase/firebase-ios-sdk#6564

I've found another package that wouldn't build called SVGKit. This is an objective-c framework, which I suspect some parts of Firebase are too. Perhaps this could be a problem?

I had a look into this with another Objective-C library we use, that is a little simpler than Firebase. It's called SnowplowTracker.

Trying to build this with scipio produces build errors:

Package.swift

// swift-tools-version: 5.6
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "Dependencies",
    platforms: [
        .iOS(.v14),
    ],
    products: [],
    dependencies: [
        .package(url: "https://github.com/snowplow/snowplow-objc-tracker", exact: "5.0.0"),
    ],
    targets: [
        .target(
            name: "Dependencies",
            dependencies: [
                .product(name: "SnowplowTracker", package: "snowplow-objc-tracker"),
            ]),
    ]
)

However I was able to build with swift-create-xcframework:

$ swift create-xcframework --platform ios SnowplowTracker
...
xcframework successfully written out to: /path/to/snowplow-objc-tracker/SnowplowTracker.xcframework

Perhaps it might be worth comparing the differences between the generated xcodebuild commands of scipio and swift-create-xcframework?
