Thanks for the feedback!

Be sure to review Apple's Watch Kit Submission Guide, and see the Troubleshooting section for any issues you may have.

  • Ensure you have:

    • Distribution Provisioning Profiles created for your projects.
    • The Deployment Target (MinimumOSVersion) for the iOS parent app set to 8.2 or earlier (8.3 is not supported).
  • In iTunes Connect:

    • Create your iOS app entry (or add a New Version to an existing app).
    • Add Watch icon and screenshots.
  • Then in Xamarin Studio (Visual Studio is not currently supported):

    • Right-click the iOS app and choose Set As Startup Project.
    • Change to the App Store configuration.
    • Use the Archive feature create an application archive.
  • Finally, switch to Xcode 6.2+

    • Go to the Window > Organizer and choose Archives.
    • Select the application and archive from the list.
    • (Optionally) Validate... the archive.
    • Submit... the archive and follow the steps to upload to iTunes Connect for review and approval.

Read specific tips related to these items below. See the Troubleshooting section if you have problems.

Distribution Provisioning Profiles

To build for App Store deployment you need to create a Distribution Provisioning Profile for each App ID in your solution.

If you have a wildcard App ID, only one Provisioning Profile will be required; but if you have a separate App ID for each project then you'll need a provisioning profile for each App ID:

Once you've created all three profiles, they'll appear in the list. Remember to download and install each one (by double-clicking on it):

You can verify the provisioning profile in the Project Options by selecting the Build > iOS Bundle Signing screen and selecting the AppStore | iPhone configuration.

The Provisioning Profile list will show all matching profiles - you should see the matching profiles that you've created in this drop-down list.

iTunes Connect

Follow the app distribution overview, in particular:

When configuring the app in iTunes Connect, don't forget to add the Watch icon and screenshots:

The icon file should be 1024x1024 pixels, and will have a circular mask applied to it when it is displayed. The icon should not have an alpha channel.

At least one screenshot is required, up to five may be submitted. They should be 312x390 pixels and demonstrate your Watch App in action. You can use the 42mm watch simulator to take screenshots at this size.

Xamarin Studio

  1. Ensure that the iOS app is the startup project. If not, right-click to set it:

  2. Choose the AppStore build configuration:

  3. Choose the Build > Archive menu item to start the archive process:

You can also choose the View > Archives... menu item to see archives that have been created previously.

Xcode

Xcode will automatically show archives created in Xamarin Studio.

  1. Start Xcode and choose Window > Organizer:

  2. Switch to the Archives tab and select the archive that was created with Xamarin Studio:

  3. Optionally Validate... the archive, then choose Submit... to upload the app to iTunes Connect.

  4. Choose the development team (if you belong to more than one) and then confirm the submission:

  5. Visit iTunes Connect again to see the uploaded binary. Go to your app's configuration page and choose Prerelease from the top menu to see the Builds list:

You can then submit the app for approval on the Versions page. Refer to the iOS app distribution overview for more information.

Troubleshooting

Here are some errors you might encounter while submitting to the App Store, and the steps you can take to fix them.

Archive menu option is not visible in Xamarin Studio

Follow the steps above to configure the solution for archiving. If you cannot set the startup project correctly, ensure the build configuration is first set to Debug or Release before attempting to change the startup project. Then set the build configuration back to AppStore.

Invalid Icon

Invalid Icon - The watch application '...watchkitextension.appex/WatchApp.app'
contains an icon file '...watchkitextension.appex/WatchApp.app/AppIcons27.5x27.5@2x.png'
with an alpha channel. Icons should not have an alpha channel.

Follow the instructions for removing the alpha channel from your icons.

CFBundleVersion Mismatch

CFBundleVersion Mismatch. The CFBundleVersion value '1' of watch application
'...watchkitextension.appex/WatchApp.app' does not match the CFBundleVersion
value '1.0' of its containing iOS application `YouriOS.app`.

All the projects in your solution - the iOS App, the Watch Extension, and the Watch App - should be using the same version number. Edit each Info.plist file so that the version number matches exactly.

Missing Icons

Missing Icons. No icons found for watch application '...watchkitextension.appex/WatchApp.app'.
Please make sure that its Info.plist file includes entries for CFBundleIconFiles.

Follow the instructions in the working with icons to add all the required images to the Watch App project.

Missing Icon

Missing Icon. The watch application '...watchkitextension.appex/WatchApp.app'
is missing icon with name pattern '*44x44@2x.png' (Home Screen 42mm).

Ensure you have the latest version of Xamarin Studio, and that your AppIcons.appiconset contains a complete set of images. If you are still seeing this error, view the source of the Contents.json to confirm it contains an entry for all the required images. Alternatively, once you have ensured you're using the latest version of Xamarin, delete and re-create the AppIcons.appiconset.

NOTE: There is a known bug in Xamarin Studio's Watch icon support: it expects an 88x88 pixel image for the 29x29@3x image (which should be 87x87 pixels).

You cannot fix this in Xamarin Studio - either edit the image asset in Xcode or manually edit the Contents.json file (to match this sample).

Invalid WatchKit Support

Invalid WatchKit Support - The bundle contains an invalid implementation of WatchKit.
The app may have been built or signed with non-compliant or pre-release tools.

This message may appear during validation and submission, or in an automated email from iTunes Connect after an apparently successful upload.

NOTE: You must Archive your app in Xamarin Studio and then switch to Xcode 6.2+ to validate and upload to iTunes Connect.

Use the Stable Xamarin channel, and Xcode 6.2+.

Invalid Provisioning Profile

Invalid Provisioning Profile. The provisioning profile included in the bundle
...iOSWatchApp.watchkitapp [iOSWatchApp.app/PlugIns/...iOSWatchApp.watchkitextension.appex/WatchApp.app]
is invalid. [Missing code-signing certificate.]

Distribution Provisioning Profiles must be supplied for all three projects in a watch app solution: the iOS App, the Watch Extension, and the Watch App - either explicitly (three profiles) or via a single wildcard profile. Check that the provisioning profiles exist in the iOS Dev Center and that you have downloaded and added them to your Mac.

Invalid Code Signing Entitlements

ITMS-90046: Invalid Code Signing Entitlements. Your application bundle's signature contains
code signing entitlements that are not supported on iOS. Specifically, value
'...watchkitextension' for key 'application-identifier' in '...watchkitextension'
is not supported. The value should be a string startign with your TEAMID, followed
by a dot '.' followed by the bundle identifier.

Ensure your provisioning profiles are set-up correctly on the Apple Dev Center, and that you have downloaded and installed them. Also check they are set in Xamarin Studio's properties window for each project.

Invalid Architecture

Invalid architecture: Apps that include an app extension
and framework must support arm64.

You can only add Watch Apps Unified API (64-bit) Xamarin.iOS apps. Right-click on the iOS app project then go to Options > Build > iOS Build > Advanced tab and ensure that the Supported Architectures for the AppStore-iPhone configuration includes ARM64 (eg. ARMv7 + ARM64).

This bundle is invalid.

ITMS-90068: This bundle is invalid. The value provided for the key
MinimumOSVersion '8.3' is not acceptable.

Your parent iOS application must have the MinimumOSVersion set to '8.2' or earlier.

Non-public API usage

Your app contains non-public API usage.
Please review the errors, and resubmit your application.

Ensure you are using the latest version of Xcode and Xamarin's tools. Your code should not access any non-public APIs.

Build Error MT5309

Error MT5309: Native linking error: clang: error: no such file or directory:

This error is likely the result of your having renamed your Xcode installation from Xcode.app. For instance, this error will occur if you rename your installation to XCode 6.2.app.

Xamarin Workbook

If it's not already installed, install the Xamarin Workbooks app first. The workbook file should download automatically, but if it doesn't, just click to start the workbook download manually.
