 Swift Package Manager is a powerful tool for managing dependencies in Swift that allows developers to enjoy a more native integration experience with Xcode.
 If you already use Swift Package Manager or prefer it over other package managers on Apple platforms, this guide will show you how to install the Kotlin Multiplatform SDK using Swift Package Manager.
-However, we recommend [installing our SDK with Cocoapods](/platforms/kotlin-multiplatform/#install) because it currently has the best compatibility with Kotlin Multiplatform.
+
+<Note>
+Adding third party dependencies through Swift Package Manager in libraries such as the Sentry SDK is not yet officially supported in the Kotlin Multiplatform ecosystem and might not be compatible in more advanced use cases. We recommend [installing our SDK with Cocoapods](/platforms/kotlin-multiplatform/#install) for the best compatibility and experience with Kotlin Multiplatform.

+## Running Tests
+
+If you configured the Sentry Kotlin Multiplatform SDK with Swift Package Manager and try running tests, it won't work out of the box and you'll encounter the following error: `ld: framework 'Sentry' not found`.
+
+Follow these steps for the workaround:
+
+### 1. Download the Sentry xcframework
+
+Choose the release based on the version specified in the version compatibility table, download the `Sentry.xcframework.zip`, and unzip it.
+
+### 2. Create Frameworks directory and insert Sentry.framework
+
+Create a `/Frameworks` directory in the directory where the `test.kexe` resides. Put the `Sentry.framework` into it. (The `Sentry.framework` can be found inside of the `ios-arm64_x86_64-simulator`.)
+The `test.kexe` will usually reside in `build/bin/iosSimulatorArm64/debugTest`.
+
+### 3. Add the linker options
+
+```kotlin {filename:shared/build.gradle.kts}
+  listOf(
+      iosX64(),
+      iosArm64(),
+      iosSimulatorArm64(),
+  ).forEach {
+      it.binaries.framework {
+          baseName = "shared"
+          isStatic = true
+      }
+      it.compilations.all {
+          if (compilationName == "test" && target.platformType == KotlinPlatformType.native) {
+              compilerOptions.configure {
+                  freeCompilerArgs.add("-linker-options")
+                  freeCompilerArgs.add("-F/your/path/Carthage/Build/Sentry.xcframework/ios-arm64_x86_64-simulator/")
+              }
+          }
+      }
+  }
+```

+### 4. Run the tests
