Searchbar filtering issue

Question

Im new to the swift, I am trying to filter name from an array using the search bar in console am getting what I entered in the search bar but filtering with predicate im not

Answer 1

let array = self.caseListOfBooker.filter{$0.person_of_interest.contains(searchString)}

You are getting array of CaseDetails objects and trying to cast to array of String

It fails. You need to get string values from the CaseDetails object and join them

Use

filteredString = array.map { $0.person_of_interest }

Or

for caseDetail in array {
    filteredString.append(caseDetail.person_of_interest)
}

Instead of

if let list = array as? [String]{
    filteredString=list
}
