How is the RestKit related to the new Watson Conversation SDK? Linker Error?

Question

I am going to update my customised sample based on Build a home assistant mobile application with Watson and IoT Platform services

I did:

1. carthage update --platform iOS
2. did the pod install
3. Using the autofix for the API Changes of the Watson Conversation Parameter inside xCode
4. Asking a question about: How to handle a concrete situation with a parameter, here on Stack Overflow

And now I got a linker error and I do not now is the error related to the update of the API or is it related to a newer xCode version, or the RestKit?

In this code I get the message:

d: framework not found RestKit clang: error: linker command failed with exit code 1 (use -v to see invocation)'

I followed some hits here in stackoverflow 1. linker command failed with exit code 1 (use -v to see invocation), build app in xcode-Cocoapods

But I was not able to find a solution which helped to fix the problem.

Answer 1

If you are using the latest release of the Watson Swift SDK, it no longer builds RestKit as a separate framework, but instead links it directly into each service. So you should be able to just remove the RestKit framework from your project.

In your particular case, you need to select the Home Assistant Project in Xcode and then the Home Assistant target.

In Build Phases, open "Link Binary with Libraries" item and delete RestKit.framework.

Then in the "Run Script" phase, delete RestKit.framework from the input files list.

With these two changes your app should build.
