I am working on developing my first ResearchKit App. I have been watching this video. One of the techniques used that is going to be helpful for me is serializing the results of a survey to JSON. The method used in the video is ORKESerializer.JSONDataForObject(taskResult). He explains that this is not a standard part of researchKit, but it was included in a test app, called ORKTest that is on GitHub.
I set up my taskViewController delegate just like he had it set on the video, like this:
extension ViewController : ORKTaskViewControllerDelegate {
func taskViewController(taskViewController: ORKTaskViewController, didFinishWithReason reason: ORKTaskViewControllerFinishReason, error: NSError?) {
switch reason {
case .Completed:
let taskResult = taskViewController.result
let jsonData = try! ORKESerializer.JSONDataForObject(taskResult)
if let jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding) {
print(jsonString)
}
break
case .Failed, .Discarded, .Saved:
break
}
//Handle results with taskViewController.result
// let taskResult = taskViewController.result
taskViewController.dismissViewControllerAnimated(true, completion: nil)
}
}
I am getting this error upon compiling : use of unresolved identifier: ORKESerializer
So in the ORKTest app, in the GitHub files, I found 2 files. One called ORKESerialization.h, and one called ORKESerialization.m. I tried dragging those into my project, as I saw those files in the man's project in the video. And then that also prompted me to create a bridging header file as well, which I also saw in his project.
After doing that I am still getting the same error. The truth is I don't know exactly how to include these serialization packages with my app. Does anyone know how to included the right files so that I can implement this ORKEserialization method?
Thanks!
