I'm trying to integrate recaptcha enterprice sdk in my ios app, built with swift. I followed the documentation mentioned here. https://cloud.google.com/recaptcha-enterprise/docs/instrument-ios-apps#swift.

I have imported the recaptcha-enterprise-mobile-sdk for ios using Swift Package Manager. the package url mentioned in the docs was https://github.com/GoogleCloudPlatform/recaptcha-enterprise-mobile-sdk.

When i try to run this block of code.

let (recaptchaClient, error) = await Recaptcha.getClient(siteKey: key)
if let recaptchaClient = recaptchaClient {
  self.recaptchaClient = recaptchaClient
}
if let error = error {
  print("RecaptchaClient creation error: \(error.errorMessage ?? "NIL").");
}

I'm getting these errors,

I solved it!

Many probably skip this point: https://cloud.google.com/recaptcha-enterprise/docs/instrument-ios-apps#configure_app

Objective - C Bridging Header

You need

  1. create an Objective-C bridging header and include the following import

To create a bridging header in your Swift project and include an import for Objective-C code, follow these steps:

  1. In Xcode, create a new header file by going to File -> New -> File (or press Command+N).

  2. Select "Header File" under the "Source" section and click "Next". Name the file "YourProjectName-Bridging-Header" (replace "YourProjectName" with the actual name of your project) and save it in your project's directory.

  3. In your project's build settings, search for "Objective-C Bridging Header" and set the value to the path of your bridging header file. For example, "YourProjectName/YourProjectName-Bridging-Header.h".

  4. Open the bridging header file you created and import the Objective-C code by adding the following line:

#import <RecaptchaEnterprise/RecaptchaEnterprise.h>

Simple Bridging Header file

Now you can access your Objective-C code from your Swift files. Make sure to import the necessary headers in your Objective-C file as well, if needed.

Note: If you don't see the "Objective-C Bridging Header" setting in your build settings, you may need to manually configure it by specifying the bridging header file path in the "Objective-C Bridging Header" build setting (under "Swift Compiler - General").

Remember to replace "YourProjectName" and "YourObjectiveCFile.h" with the appropriate names for your project and Objective-C file.

Build Setting image

  1. Ensure that -ObjC is listed on your linker flags. Navigate to Target > Build Settings > All > Linking and verify that Other Linker Flags shows -ObjC.
