Check if array contains part of a string in Swift?

Question

I have an array containing a number of strings. I have used contains() (see below) to check if a certain string exists in the array however I would like to chec

Answer 1

Try like this.

let itemsArray = ["Google", "Goodbye", "Go", "Hello"]
let searchToSearch = "go"

let filteredStrings = itemsArray.filter({(item: String) -> Bool in

     var stringMatch = item.lowercaseString.rangeOfString(searchToSearch.lowercaseString)
     return stringMatch != nil ? true : false
})

filteredStrings will contain the list of strings having matched sub strings.

In Swift Array struct provides filter method, which will filter a provided array based on filtering text criteria.

MARK:- Swift 5, Swift 4

//MARK:- You will find the array when its filter in "filteredStrings" variable you can check it by count if count > 0 its means you have find the results

let itemsArray = ["Google", "Goodbye", "Go", "Hello"]
let searchToSearch = "go"

let filteredStrings = itemsArray.filter({(item: String) -> Bool in

    let stringMatch = item.lowercased().range(of: searchToSearch.lowercased())
    return stringMatch != nil ? true : false
})
print(filteredStrings)


if (filteredStrings as NSArray).count > 0
{
    //Record found
    //MARK:- You can also print the result and can do any kind of work with them
}
else
{
    //Record Not found
}

In Swift 4:

    let itemsArray = ["Google", "Goodbye", "Go", "Hello"]
    let searchString = "Go"
    let filterArray = itemsArray.filter({ { $0.range(of: searchString, options: .caseInsensitive) != nil}
    })
    print(filterArray)
