Your SDK Verification

Here you will learn how to check your SDK XCFramework and make sure it has no direct dependency on the Group Link SDK.

Step 1 - Check your SDK XCFramework​

Build your SDK with your usual process and then check the generated XCFramework:

grep -l GroupLinkStatic <YOUR_PROJECT_PATH>/<YOUR_SDK>.xcframework/ios-arm64/<YOUR_SDK>.framework/Modules/<YOUR_SDK>.swiftmodule/*.swiftinterface
  • grep: must return nothing, meaning there is no reference to GroupLinkStatic in your SDK module.

Commands for a DYNAMIC SDK​

otool -L <YOUR_PROJECT_PATH>/<YOUR_SDK>.xcframework/ios-arm64/<YOUR_SDK>.framework/<YOUR_SDK> | grep -i grouplink
  • otool: must return nothing, meaning there is no reference to GroupLinkStatic in your SDK dynamic dependencies list.
nm -m <YOUR_PROJECT_PATH>/<YOUR_SDK>.xcframework/ios-arm64/<YOUR_SDK>.framework/<YOUR_SDK> | grep -c GroupLinkStatic
  • nm: must return a number greater than 0, meaning the GroupLinkStatic code is inside your SDK dynamic binary.

Command for a STATIC SDK​

ar -t <YOUR_PROJECT_PATH>/<YOUR_SDK>.xcframework/ios-arm64/<YOUR_SDK>.framework/<YOUR_SDK> | grep GroupLink
  • ar: must return 1 line, meaning GroupLinkStatic is inside your SDK static archive.

[OPTIONAL] - Check your SDK Swift Package dependencies​

If your SDK is distributed as a Swift Package, it is important to check that it has no direct dependency on the Group Link SDK.

In your SDK Package.swift:

  • Check that your SDK does not have dependencies: on iOSGrouplinkStatic.

Example of a Package.swift with no dependency on iOSGrouplinkStatic

// swift-tools-version:5.9

import PackageDescription

let package = Package(
    name: "YourSDK",
    platforms: [
        .iOS(.v13)
    ],
    products: [
        .library(
            name: "YourSDK",
            targets: ["YourSDK"]
        )
    ],
    dependencies: [
        // ...
        // No dependency on iOSGrouplinkStatic
    ],
    targets: [
        .binaryTarget(
            name: "YourSDK",
            path: "YourSDK.xcframework"
        )
    ]
)
