+          This package contains Swift bindings for ARK Drop.
+
+          ## Contents
+
+          - `arkdrop_uniffiFFI.xcframework` - Pre-built XCFramework for iOS and macOS
+          - `Sources/ArkDrop/ArkDrop.swift` - Swift bindings generated by UniFFI
+          - `Package.swift` - Swift Package Manager configuration
+          - `arkdrop_uniffiFFI.h` - C header file (reference)
+          - `module.modulemap` - Module map (reference)
+
+          ## Installation
+
+          ### Swift Package Manager
+
+          Add to your `Package.swift`:
+
+          ```swift
+          dependencies: [
+              .package(path: "path/to/ArkDrop-Swift-Package")
+          ]
+          ```
+
+          Or add the extracted package directory to your Xcode project via:
+          File → Add Package Dependencies → Add Local...
+
+          ## Usage
+
+          Import the module in your Swift code:
+
+          ```swift
+          import ArkDrop
+          ```
+          EOF
+
+          # List package contents
+          echo ""
+          echo "Package contents:"
+          find ArkDrop-Swift-Package -type f | sort
+
+          # Create a zip archive
+          echo ""
+          echo "Creating archive..."
+          zip -r ArkDrop-Swift-Package.zip ArkDrop-Swift-Package/
+
+          # Create checksum
+          echo "Creating checksum..."

+            ## Swift Bindings for ARK Drop
+
+            This release contains the Swift bindings for ARK Drop, including:
+            - XCFramework for iOS (device and simulator) and macOS
+            - Swift source files
+            - Swift Package Manager configuration
+
+            ### Installation
+
+            #### Swift Package Manager
+
+            1. Download and extract `ArkDrop-Swift-Package.zip`
+            2. Add the package to your Xcode project or include it in your `Package.swift`:
+
+            ```swift
+            dependencies: [
+                .package(path: "path/to/ArkDrop-Swift-Package")
+            ]
+            ```
+
+            #### Manual Installation
+
+            1. Download `ArkDrop-Swift-Package.zip`
+            2. Extract and add `arkdrop_uniffiFFI.xcframework` to your Xcode project
+            3. Add `drop.swift` to your project sources
+
+            ### Verification
+
+            Verify the package integrity using the SHA256 checksum:
+            ```bash
+            shasum -a 256 -c ArkDrop-Swift-Package.zip.sha256
+            ```
