Intermittent dependency problems

[denizdogan]

I have always had intermittent issues with resolving package dependencies when using Tuist for generating my project. Below is the last part of the error log.

$ tuist clean && tuist fetch && tuist generate -n

Consider creating an issue using the following link: https://github.com/tuist/tuist/issues/new/choose

Re-running the command resolves the issue. Sometimes I'll have to re-run it again. That's why I'm saying it's intermittent, it's almost random. It works maybe 80% of the time. This has gone on ever since I started using Tuist some months ago.

After Tuist succeeds, sometimes Xcode will still fail with strange errors about the dependencies, and then it's about all of the project dependencies, not specifically this Facebook one. Right-clicking "Package Dependencies" in the sidebar and choosing "Reset Package Caches" resolves that problem.

Unforuntately I can't show you the entire Tuist configuration (not a public project), but basically I have a few relatively simple targets with the following dependencies:

.package(product: "FacebookCore"),
.package(product: "FacebookLogin"),
.package(product: "FacebookShare"),

The Tuist project has an SPM dependency as such:

.remote(url: "https://github.com/facebook/facebook-ios-sdk", requirement: .upToNextMinor(from: "13.2.0")),

The Dependencies object is defined as follows, with the seemingly non-offending dependencies redacted:

let dependencies = Dependencies(
  swiftPackageManager: SwiftPackageManagerDependencies(
    [
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(url: "https://github.com/facebook/facebook-ios-sdk", requirement: .upToNextMinor(from: "13.2.0")),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .remote(...),
      .local(path: "..."),
    ],
    productTypes: [
      "...": .staticLibrary,
    ],
    targetSettings: [
      "...": [
        "MODULEMAP_FILE": "...",
      ],
    ]
  ),
  platforms: [.iOS]
)

The Config is defined simply as:

let config = Config(
  compatibleXcodeVersions: .upToNextMajor("13.3"),
  swiftVersion: "5.6"
)

Any ideas what's going on here?

Tuist version: 3.3.0
Xcode version: 14.3.1
macOS 12.4 on M1

You should use .external, not .package to define external dependencies
