Uninstall single package from grouped packages in Swift Package Manager

[ghost]

I installed the following packages from the AWS SDK for iOS (https://github.com/aws-amplify/aws-sdk-ios-spm):

AWSCognitoIdentityProvider

AWSMobileClientXCF

I no longer need AWSCognitoIdentityProvider. It was imported into only one file, and then that import was later removed, and I've confirmed that it is not being imported anywhere else.

I can't seem to uninstall only this package. All attempts to do so cause build errors related to AWSMobileClientXCF.

The installation appears in Xcode as a single package called AWSiOSSDKV2, both in the navigator and in the Project > Package Dependencies section, so I can't just remove the one I no longer need.

The only place I can find a mention of AWSCognitoIdentityProvider is in Target > Build Phases > Link Binary With Libraries.

I've tried various combinations of the following steps:

• Uninstall the entire package, then reinstall and select only the one I need
• Remove the other package from Target > Build Phases > Link Binary With Libraries
• Clean the Build folder
• Delete the Products folder
• Delete the DerivedData folder
• Reset the package caches

Every time I try to build after performing some or all of these steps, it fails. The exact error depends on which combination of the above steps I attempted.

For example, this is one attempt:

1. Uninstall the entire package
2. Delete DerivedData
3. Clean the build folder
4. Install the package and select only AWSMobileClientXCF
5. Clean the build folder
6. Build - Failure

Errors:

Command SwiftCompile failed with a nonzero exit code

someFileOfMine: Failed to build module 'AWSMobileClientXCF'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.7.2 (swiftlang-5.7.2.135.5 clang-1400.0.29.51)', while this compiler is 'Apple Swift version 5.10 (swiftlang-5.10.0.13 clang-1500.3.9.4)'). Please select a toolchain which matches the SDK.

arm-64-apple-ios-simulator.private: Could not build Objective-C module 'AWSCognitoIdentityProvider'

AWSCognitoIdentityProvider: 'AWSCore/AWSCore.h' file not found

Immediately after this I did the following:

1. Close the simulator
2. Clean the build folder
3. Build - Failure

Errors this time:

Missing package product 'AWSMobileClientXCF'

someFileOfMine: No such module 'AWSMobileClientXCF'

In AWSiOSSDKV2 > Package.swift, I see this:

extension Target.Dependency {
    // Framework dependencies present in the SDK
    static let awsCore: Self = .target(name: "AWSCore")
    static let awsAuthCore: Self = .target(name: "AWSAuthCore")
    static let awsCognitoIdentityProviderASF: Self = .target(name: "AWSCognitoIdentityProviderASF")
    static let awsCognitoIdentityProvider: Self = .target(name: "AWSCognitoIdentityProvider")
}

Does this mean AWSCognitoIdentityProvider must also be installed? I can't see how that would be the case since I never had installed AWSCore or AWSAuthCore. If this is the case, I can install it again, but I want to be sure so I don't have unused packages installed.

How can I remove this package I no longer need?

Hi @occassionally, thanks for reaching out.

Yes, AWSCognitoIdentityProvider is a required dependency of AWSMobileClientXCF.
