Scipio v0.30.0 could not build Firebase 11.15.0

[r-plus]

We can build firebase v11.15.0 with Scipio v0.29.1 but could not with v0.30.0.
This is Package.swift for scipio.

// swift-tools-version: 6.0

import PackageDescription

let package = Package(
    name: "Dependencies",
    platforms: [
        .iOS(.v16),
    ],
    products: [],
    dependencies: [
        .package(url: "https://github.com/firebase/firebase-ios-sdk", exact: "11.15.0"),
    ],
    targets: [
        .target(
            name: "Dependencies",
            dependencies: [
                .product(name: "FirebaseRemoteConfig", package: "firebase-ios-sdk"),
            ]
        ),
    ]
)

issue is similar to #239 but we are not receiving signal 5.

[mackoj]

I have the same issue but with my own package that used to work with Scipio, this issue appeared after updating to the 0.30.

[S-Shimotori]

According to my investigation, three issues may occur by current Scipio and firebase-ios-sdk.

DecodedError.typeMismatch due to warning control settings

PackageManifestKit didn't support the warning control settings, .disableWarning("...").

I already fixed PackageManifestKit, and we need to update Scipio's Package.swift.
giginet/PackageManifestKit#1

Swift Build only accepts an absolute path of DerivedData, but Scipio on CLI passes a relative path.

unable to write module session file at 'Dependencies/.build/scipio/DerivedData/ModuleCache.noindex/Session.modulevalidation': unknown error

I think this is a bug of Swift Build.
swiftlang/swift-build#944

I opened a PR to add a workaround to Scipio.
#256

Swift Build on CLI fails to find a Info.plist in some cases.

Build input file cannot be found: '/absolute/path/to/package/.build/checkouts/promises/.build/scipio/Info-Promises_FBLPromises.plist'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it?

There is .build/scipio/Info-Promises_FBLPromises.plist, but Swift Build looks for .build/checkouts/promises/.build/scipio/Info-Promises_FBLPromises.plist.

I'm still investigating when and how Swift Build causes. IMO a relative path from evaluate(BuiltinMacros.INFOPLIST_FILE) causes this issue.

FYI: This issue doesn't occur when Scipio creates APNGKit.xcframework.

[r-plus]

not yet resolved on 40f93e2 cause probably swbuild issue. (using Xcode 26.1.1)

[GoogleUtilities_GoogleUtilities-NSData#23] Build input file cannot be found: '/Users/r0107/gitclone/project/Dependencies/.build/checkouts/GoogleUtilities/Dependencies/.build/scipio/Info-GoogleUtilities_GoogleUtilities-NSData.plist'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it?
[GoogleUtilities_GoogleUtilities-NSData#23] failed

correct path is /Users/r0107/gitclone/project/Dependencies/.build/scipio/Info-GoogleUtilities_GoogleUtilities-NSData.plist in this case.

[r-plus]

Thanks for update but still not resolved on d4131d0 with Xcode 26.1.1 and 26.2
I should keep v0.29.1 for now.

[r-plus]

I try to bisect the merge commit between v0.29.1 and v0.30.0 to detect when Firebase no longer builds.
Resultly, e6c60cc is success; a294117 is failed.
I hope this research will be of some help.

[giginet]

Sorry for waiting for such a long time.

I tried this situation with the prepare mode using the latest version 0.32.0, it seems to be succeeded.

Could you try this?
