How to search on a search bar on the basis of Core-Data entity and attribute

By firing an API, I am getting a certain list of titles which I am storing in an array like so:

self.arr1.updateValue(user, forKey: "title") and
self.sampleArray.append(self.arr1["title"] as! String)

Now sampleArray has all the titles I need and I need to filter on the basis of these titles. My coredata model has an entity called Posts and attributes content,title.

Also, currently this is how I am filtering:

    filtered = sampleArray.filter({ (text) -> Bool in
                let tmp: NSString = text as NSString
                let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
                return range.location != NSNotFound
            })

Here, sampleArray has just a list of names and those names are added to the array named 'filtered', but the issue is that on clicking a row we go to a webview using segue and that webview has some content in a paragraph. Clicking on each of the row shows the webview with a different data. With this filtering that I am doing above, when I click on the row I get after filtering, the webview data shown is incorrect. In other words, I am not able to figure out how I will pass the correct array so that the correct webview content is shown.

My entity 'Posts' has the attributes 'title' and 'content'. If I can filter the Posts and then get the title from it, then I think I can get the content also, but I am not able to figure out how that is done.

You are searching on the basis of just the attributes while you are to search on the basis of your managed object array. Try this format...

filtered = self.arrayOfYourManagedObjectType.filter { ($0.title?.lowercased().contains(searchText.lowercased()))! }

What do you mean by appropriate content after clicking on filtered result ??. Usually, you can filter list of values either by using filteredArrayUsingPredicate or filter method.
