Inner filtering of array doesn't filter swift - swift

Question

I am trying to filter an array of structs that has array. Below are the data structures I am using. I want the inner array filtered also but it doesn't work
var objects = [SomeObject]() //array of objects
var filteredObject = [SomeObject]() //filtered array
var isSearching = false
struct SomeObject {
var sectionName: String
var sectionObjects : [History]
}
struct History {
var firstName: String
var lastName: Int
}
func searchBar(_ text: String) {
filteredObject = objects.filter({ (obj: SomeObject) -> Bool in
return obj.sectionObjects.filter { $0.firstName.contains(text.lowercased())}.isEmpty
})
print("====", filteredObject, "fill===")
}
let history = History(firstName: "John", lastName: 1)
let anotherHistroy = History(firstName: "Dee", lastName: 2)
let historyArray = [history, anotherHistroy]
let newObject = SomeObject(sectionName: "Section 1", sectionObjects: historyArray)
objects.append(newObject)
searchBar("Jo") // printing of filtered object should not have another history in it's sectionObjects

Answer 1

You might be looking for something like this:
func searchBar(_ text: String) {
filteredObject = []
for var ob in objects {
ob.sectionObjects = ob.sectionObjects.filter {
$0.firstName.contains(text)
}
if !ob.sectionObjects.isEmpty {
filteredObject.append(ob)
}
}
print("====", filteredObject, "fill===")
}
Could perhaps be done more elegantly with reduce(into:), but on the whole it is best to start simply by saying exactly what you mean. You can tweak as desired to take account of case sensitivity.
