iOS

Review Xcode project settings

This step covers reviewing the most important settings in the Xcode workspace. For detailed procedures and descriptions, see Prepare for app distribution.

Navigate to your target’s settings in Xcode:

  1. In Xcode, open Runner.xcworkspace in your app’s ios folder.
  2. To view your app’s settings, select the Runner project in the Xcode project navigator. Then, in the main view sidebar, select the Runner target.
  3. Select the General tab.

Verify the most important settings.

In the Identity section:

Display Name
Runner
Bundle Identifier
The App ID you registered on App Store Connect.

In the Signing & Capabilities section:

Automatically manage signing
Whether Xcode should automatically manage app signing and provisioning. This is set true by default, which should be sufficient for most apps. For more complex scenarios, see the Code Signing Guide.
Team
Select the team associated with your registered Apple Developer account. If required, select Add Account…, then update this setting.

In the Deployment Info section:

Deployment Target:
The minimum iOS version that your app supports. Flutter supports iOS 8.0 and later. If your app includes Objective-C or Swift code that makes use of APIs that were unavailable in iOS 8, update this setting appropriately.

The General tab of your project settings should resemble the following:

Xcode Project Settings

For a detailed overview of app signing, see Create, export, and delete signing certificates.

Updating the app’s name

In the main view sidebar, select the Info.plist file. Rename the Bundle name field.

Updating the app’s version number

The default version number of the app is 1.0.0. To update it, navigate to the pubspec.yaml file and update the following line:

version: 1.0.0+1

The version number is three numbers separated by dots, such as 1.0.0 in the example above, followed by an optional build number such as 1 in the example above, separated by a +.

Both the version and the build number may be overridden in Flutter’s build by specifying --build-name and --build-number, respectively.

In iOS, build-name uses CFBundleShortVersionString while build-number uses CFBundleVersion. Read more about iOS versioning at Core Foundation Keys on the Apple Developer’s site.

Add an app icon

When a new Flutter app is created, a placeholder icon set is created. This step covers replacing these placeholder icons with your app’s icons:

  1. Review the iOS App Icon guidelines.
  2. In the Xcode project navigator, select Assets.xcassets in the Runner folder. Update the placeholder icons with your own app icons.
  3. Verify the icon has been replaced by running your app using flutter run.

Create a build archive

This step covers creating a build archive and uploading your build to App Store Connect.

During development, you’ve been building, debugging, and testing with debug builds. When you’re ready to ship your app to users on the App Store or TestFlight, you need to prepare a release build. At this point, you might consider obfuscating your Dart code to make it more difficult to reverse engineer. Obfuscating your code involves adding a couple flags to your build command.

On the command line, follow these steps in your application directory:

  1. Run flutter build ios to create a release build ( flutter build defaults to --release).
  2. To ensure that Xcode refreshes the release mode configuration, close and re-open your Xcode workspace. For Xcode 8.3 and later, this step is not required.

In Xcode, configure the app version and build:

  1. In Xcode, open Runner.xcworkspace in your app’s ios folder.
  2. Select Product > Scheme > Runner.
  3. Select Product > Destination > Generic iOS Device.
  4. Select Runner in the Xcode project navigator, then select the Runner target in the settings view sidebar.
  5. In the Identity section, update the Version to the user-facing version number you wish to publish.
  6. In the Identity section, update the Build identifier to a unique build number used to track this build on App Store Connect. Each upload requires a unique build number.

Finally, create a build archive and upload it to App Store Connect:

  1. Select Product > Archive to produce a build archive.
  2. In the sidebar of the Xcode Organizer window, select your iOS app, then select the build archive you just produced.
  3. Click the Validate App button. If any issues are reported, address them and produce another build. You can reuse the same build ID until you upload an archive.
  4. After the archive has been successfully validated, click Distribute App. You can follow the status of your build in the Activities tab of your app’s details page on App Store Connect.

You should receive an email within 30 minutes notifying you that your build has been validated and is available to release to testers on TestFlight. At this point you can choose whether to release on TestFlight, or go ahead and release your app to the App Store.

For more details, see Upload an app to App Store Connect.

Release your app on TestFlight

TestFlight allows developers to push their apps to internal and external testers. This optional step covers releasing your build on TestFlight.

  1. Navigate to the TestFlight tab of your app’s application details page on App Store Connect.
  2. Select Internal Testing in the sidebar.
  3. Select the build to publish to testers, then click Save.
  4. Add the email addresses of any internal testers. You can add additional internal users in the Users and Roles page of App Store Connect, available from the dropdown menu at the top of the page.

For more details, see Distribute an app using TestFlight.

Release your app to the App Store

When you’re ready to release your app to the world, follow these steps to submit your app for review and release to the App Store:

  1. Select Pricing and Availability from the sidebar of your app’s application details page on App Store Connect and complete the required information.
  2. Select the status from the sidebar. If this is the first release of this app, its status is 1.0 Prepare for Submission. Complete all required fields.
  3. Click Submit for Review.

Apple notifies you when their app review process is complete. Your app is released according to the instructions you specified in the Version Release section.

For more details, see Distribute an app through the App Store.

The Distribute your app guide provides a detailed overview of the process of releasing an app to the App Store.
