"exportOptionsPlist error for key 'method': expected one of {}, but found -1"

Understanding the Problem:

In your Azure DevOps pipeline, while executing a task for Xcode (Task Name: Xcode@5), you are encountering the following error:

vbnet

Copy code

Error Domain=IDEFoundationErrorDomain Code=1 "exportOptionsPlist error for key 'method': expected one of {}, but found development" UserInfo={NSLocalizedDescription=exportOptionsPlist error for key 'method': expected one of {}, but found development}.

This error specifically refers to the exportOptionsPlist configuration used when exporting your iOS app from Xcode. The error indicates that Xcode expects one of a set of predefined values for the method key, but it encountered the value "development" instead, which it doesn't recognize.

Common Causes and Solutions:

Xcode export method is set incorrectly
The key in question here is method, which dictates the type of distribution or signing you're using for your app when exporting it. This can be one of the following options:

app-store

ad-hoc

enterprise

development

validation

However, the error message you received suggests that the value "development" is not being accepted. It may be due to one of the following:

The exportOptionsPlist file is not correctly configured.

The build configuration in your pipeline does not match what Xcode expects.

A mismatch between provisioning profiles or certificates and the specified method.

Fixing the exportOptionsPlist configuration
The exportOptionsPlist file is crucial for defining how Xcode should export the build for distribution. If you are using a development provisioning profile (which is typical for local development and testing), it must be explicitly recognized and configured.

Here's how you can troubleshoot and resolve the issue:

Step-by-Step Guide:

Step 1: Check Your exportOptionsPlist Configuration

The exportOptionsPlist is a file that contains a dictionary of export options used by Xcode when exporting the IPA. The method key specifies how the app should be exported.

For Development builds, the method should typically be set to "development".

For Ad-Hoc distribution, it should be "ad-hoc".

For App Store distribution, it should be "app-store".

Ensure your exportOptionsPlist file looks like the following for development:

xml

Copy code

<?xml version="1.0" encoding="UTF-8"?> method development teamID Your-Team-ID provisioningProfiles com.example.yourapp your-development-profile signingStyle automatic

Key Points to Check:

Correct Method: Ensure that method is correctly set to "development". If you're building for something other than development (like Ad-Hoc or App Store), use the respective method.

Provisioning Profiles: Ensure that the correct development provisioning profile is associated with your app identifier.

Signing Style: Ensure the signing style is set to automatic (unless you're manually managing your signing certificates and profiles).

Step 2: Update Your Pipeline YAML to Include Correct Export Options

In the Azure DevOps pipeline YAML, the task Xcode@5 might require specific parameters for handling export options. Here is a basic example of how to include an export options plist for a development build:

yaml

Copy code

- task: Xcode@5 displayName: 'Build and Export iOS App' inputs: actions: 'build,archive' sdk: 'iphoneos' configuration: 'Release' signingOption: 'manual' signingIdentity: 'iPhone Developer' provisionProfileUuid: 'Your-Profile-UUID' exportMethod: 'development' # Make sure this matches your exportOptionsPlist configuration exportOptions: '$(Build.SourcesDirectory)/path/to/ExportOptions.plist' xcodeVersion: 'latest'

Make sure to replace '$(Build.SourcesDirectory)/path/to/ExportOptions.plist' with the correct path to your export options file.

Step 3: Verify Provisioning Profile

In order for the export method to work correctly, the provisioning profile must match the method. If you are building using the development method, ensure the following:

You have a valid development provisioning profile in your Apple Developer account.

The provisioning profile is linked to your app's bundle identifier and team.

You have the correct certificate installed on your build agent (the machine that runs the pipeline).

Step 4: Verify Build Configuration

Ensure that the build configuration is set correctly. For example, use Release for production builds, and Debug for development or testing.

Step 5: Debugging the Error Message

If you're still facing issues, it may help to add additional debugging output to your pipeline. You can increase the verbosity of the build process to get more insights into what Xcode is doing.

You can also try running the build locally on your macOS machine to see if the same error occurs. This can help isolate whether the issue is specific to the Azure DevOps environment or the Xcode configuration itself.

FAQ: Azure DevOps Pipeline Xcode@5 ExportOptionsPlist Error

Q1: What is the purpose of the exportOptionsPlist file?

A1: The exportOptionsPlist file is used by Xcode when exporting an IPA file for distribution. It provides essential information about how the app should be packaged, including the distribution method (development, ad-hoc, app-store, etc.), provisioning profiles, and signing options.

Q2: How do I fix the error expected one of {}, but found development?

A2: This error typically happens when the method specified in the exportOptionsPlist does not match the expected values in Xcode. Ensure the method is set correctly in the plist file, typically "development" for development builds, and that your provisioning profiles are configured properly.

Q3: Can I use the "development" method for an app that is already live on the App Store?

A3: No, the "development" method is for testing purposes and cannot be used for apps that are distributed via the App Store. If you want to distribute an update to an App Store app, you should use the "app-store" export method instead.

Q4: How do I know if I have the correct provisioning profile for development?

A4: You can check your Apple Developer account to see if you have a valid development provisioning profile associated with your app. The profile must be linked to the app’s bundle identifier and should be marked as valid for development.

Q5: What should I do if I don’t have the development method in my exportOptionsPlist?

A5: If you don’t have a development option, ensure that your Xcode version supports it and that your provisioning profiles and certificates are set up correctly. You may also want to ensure that your Apple Developer account is active and that your team has valid certificates.

Q6: Can I automate this process in Azure DevOps?

A6: Yes, Azure DevOps allows you to automate the process of building and exporting iOS apps using the Xcode@5 task. Make sure your pipeline is configured correctly with the necessary parameters and export options to match your app's distribution requirements.

Conclusion

The error you're encountering typically occurs due to mismatched configurations in your exportOptionsPlist file or in the Azure DevOps pipeline. To resolve the issue, ensure that the method you are using in the plist matches the one expected by Xcode, verify the provisioning profiles, and check that the signing identities are correct. Debugging locally and adjusting the pipeline configuration should help resolve the issue and get your iOS app exported successfully.
