I have an arrays

var searchArray = [(
 ean: String,
 name: String,
 weight: String,
 brand: String,
 percent: String,
 inside: String,
 img: String,
 packet: String,
 date: String)
 ]()

var searchArrayFiltered = [(
 ean: String,
 name: String,
 weight: String,
 brand: String,
 percent: String,
 inside: String,
 img: String,
 packet: String,
 date: String)
 ]()

I have a code for search from arrays and show result in table:

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
 searchArrayFiltered = searchText.isEmpty ? searchArray : searchArray.filter((dataString: String) -> Bool in
 return dataString.(of: searchText, options: .caseInsensitive) != nil
 )

 tableView.reloadData()

But in line return dataString.String(of: searchText, options: .caseInsensitive) != nil i have an error:

Value of tuple type '(ean: String, name: String, weight: String,
brand: String, percent: String, inside: String, img: String, packet:
String, date: String)' has no member 'String'

If I change dataString.String to dataString.name, I have an error:

Cannot call value of non-function type 'String'

Please help me to do search from searchArray for "name".

First of all you are discouraged from using a tuple as array type. Use a custom struct or class

Apple says:

Tuples are useful for temporary groups of related values. They’re not suited to the creation of complex data structures. If your data structure is likely to persist beyond a temporary scope, model it as a class or structure, rather than as a tuple.

There are two major issues:

1. Copy&Paste mistake, you mean dataString.range(of...
   


2. 
   dataString is not a string, it's a tuple (the type annotation is redundant)

Change the function to

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
 searchArrayFiltered = searchText.isEmpty ? searchArray : searchArray.filter(tuple -> Bool in
 return tuple.name.range(of: searchText, options: .caseInsensitive) != nil
 )

 tableView.reloadData()

create a struct for

struct Model 
 var ean: String
 var name: String
 var weight: String
 var brand: String
 var percent: String
 var inside: String
 var img: String
 var packet: String
 var date: String

then apply filter on your [Model]
