<title>Building macOS apps with Flutter</title>
<location>https://docs.flutter.dev/platform-integration/macos/building</location>
<excerpt>Building macOS apps with Flutter # Building macOS apps with Flutter Platform-specific considerations for building for macOS with Flutter. This page discusses considerations unique to building macOS apps with Flutter, including shell integration and distribution of macOS apps through the Apple Store. ## Integrating with macOS look and feel While you can use any visual style or theme you choose to build a macOS app, you might want to adapt your app to more fully align with the macOS look and feel. Flutter includes the Cupertino widget set, which provides a set of widgets for the current iOS design language. Many of these widgets, including sliders, switches and segmented controls, are also appropriate for use on macOS. Alternatively, you might find the macos_ui package a good fit for your needs. This package provides widgets and themes that implement the macOS design language, including a `MacosWindow` frame and scaffold, toolbars, pulldown and pop-up buttons, and modal dialogs. ## Building macOS apps To distribute your macOS application, you can either distribute it through the macOS App Store, or you can distribute the `.app` itself, perhaps from your own website. You need to notarize your macOS application before distributing it outside the macOS App Store. The first step in both of the above processes involves working with your application inside of Xcode. To be able to compile your application from inside of Xcode you first need to build the application for release using the `flutter build` command, then open the Flutter macOS Runner application. bash ``` flutter build macos open macos/Runner.xcworkspace ``` Once inside of Xcode, follow either Apple&`#39`;s documentation on notarizing macOS Applications, or on distributing an application through the App Store. You should also read through the macOS-specific support section below to understand how entitlements, the App Sandbox, and the Hardened Runtime impact your distributable application. Build and release a macOS app provides a more detailed step-by-step walkthrough of releasing a Flutter app to the App Store. ## Entitlements and the App Sandbox macOS builds are configured by default to be signed, and sandboxed with App Sandbox. This means that if you want to confer specific capabilities or services on your macOS app, such as the following: - Accessing the internet - Capturing movies and images from the built-in camera - Accessing files Then you must set up specific entitlements in Xcode. The following section tells you how to do this. ### Setting up entitlements Managing sandbox settings is done in the `macos/Runner/*.entitlements` files. When editing these files, you shouldn&`#39`;t remove the original `Runner-DebugProfile.entitlements` exceptions (that support incoming network connections and JIT), as they&`#39`;re necessary for the `debug` and `profile` modes to function correctly. If you&`#39`;re used to managing entitlement files through the Xcode capabilities UI, be aware that the capabilities editor updates only one of the two files or, in some cases, it creates a whole new entitlements file and switches the project to use it for all configurations. Either scenario causes issues. We recommend that you edit the files directly. Unless you have a very specific reason, you should always make identical changes to both files. If you keep the App Sandbox enabled (which is required if you plan to distribute your application in the App Store), you need to manage entitlements for your application when you add certain plugins or other native functionality. For instance, using the `file_selector` plugin requires adding either the `com.apple.security.files.user-selected.read-only` or `com.apple.security.files.user-selected.read-write` entitlement. Another common entitlement is `com.apple.security.network.client`, which you must add if you make any network requests. Without the `com.apple.security.network.client` entitlement, for example, network requests fail with a messag…[truncated]</excerpt>

<excerpt>Set up macOS development # Set up macOS development Configure your development environment to run, build, and deploy Flutter apps for macOS devices. Learn how to set up your development environment to run, build, and deploy Flutter apps for the macOS desktop platform. info Note If you haven&`#39`;t set up Flutter already, visit and follow Install Flutter first. If you&`#39`;ve already installed Flutter, ensure that it&`#39`;s up to date. ## Set up tooling With Xcode, you can run Flutter apps on macOS as well as compile and debug native Swift and Objective-C code. 1. ### Install Xcode If you haven&`#39`;t done so already, install and set up the latest version of Xcode. If you&`#39`;ve already installed Xcode, update it to the latest version using the same installation method you used originally. 2. ### Set up Xcode command-line tools To configure the Xcode command-line tools to use the version of Xcode you installed, run the following command in your preferred terminal: ``` $ sudo sh -c &`#39`;xcode-select -s /Applications/Xcode.app/Contents/Developer &amp;&amp; xcodebuild -runFirstLaunch&`#39`; ``` content_copy If you downloaded Xcode elsewhere or need to use a different version, replace `/Applications/Xcode.app` with the path to there instead. 3. ### Agree to the Xcode licenses After you&`#39`;ve set up Xcode and configured its command-line tools, agree to the Xcode licenses. 1. Open your preferred terminal. 2. Run the following command to review and sign the Xcode licenses. ``` $ sudo xcodebuild -license ``` content_copy 3. Read and agree to all necessary licenses. Before agreeing to the terms of each license, read each with care. Once you&`#39`;ve accepted all the necessary licenses successfully, the command should output how to review the licenses. 4. ### Install CocoaPods To support Flutter plugins that use native macOS code, install the latest version of CocoaPods. Install CocoaPods following the CocoaPods installation guide. If you&`#39`;ve already installed CocoaPods, update it following the CocoaPods update guide. ## Validate your setup 1. ### Check for toolchain issues To check for any issues with your macOS development setup, run the `flutter doctor` command in your preferred terminal: ``` $ flutter doctor -v ``` content_copy If you see any errors or tasks to complete under the Xcode section, complete and resolve them, then run `flutter doctor -v` again to verify any changes. 2. ### Check for macOS devices To ensure Flutter can find and connect to your macOS device correctly, run `flutter devices` in your preferred terminal: ``` $ flutter devices ``` content_copy If you set everything up correctly, there should be at least one entry with the platform marked as macos. 3. ### Troubleshoot setup issues If you need help resolving any setup issues, check out Install and setup troubleshooting. If you still have issues or questions, reach out on one of the Flutter community channels. ## Start developing for macOS Congratulations! Now that you&`#39`;ve set up macOS desktop development for Flutter, you can continue your Flutter learning journey while testing on macOS or begin expanding integration with macOS. - Build and deploy to macOS - Bind to native macOS code - Embed native macOS views - Set up app flavors - Use Swift Package Manager</excerpt>

Pass the smoke condition through Flutter's supported Xcode setting path.

XCODE_XCCONFIG_FILE is not consumed by the flutter build macos invocation. Flutter 3.41.0 forwards only FLUTTER_XCODE_* variables to xcodebuild. The PacketTunnel Profile target therefore builds without VPN_SMOKE_TEST.

The extension omits request loading, failAfterSettings, forced fallback, and result recording. waitForResult then can wait 60 seconds and fail for failed-after-settings; each fallback request would also time out if reached.

Suggested fix 
-          printf '%s\n' 'SWIFT_ACTIVE_COMPILATION_CONDITIONS = $(inherited) VPN_SMOKE_TEST' \
-            > "$RUNNER_TEMP/vpn-smoke.xcconfig"
-          echo "XCODE_XCCONFIG_FILE=$RUNNER_TEMP/vpn-smoke.xcconfig" >> "$GITHUB_ENV"
+          echo 'FLUTTER_XCODE_SWIFT_ACTIVE_COMPILATION_CONDITIONS=$(inherited) VPN_SMOKE_TEST' \
+            >> "$GITHUB_ENV"
