How search in Array with similar data? Swift

Question

I want to search a string in array and get all indexes at which string is present.

My Array consisting of json data coming from server is.

["Non Native", "Native", "Native & Non Native"]

The method I am using is

let indexArray = demand.indices.filter {
   demand[$0].localizedCaseInsensitiveContains("Native") 
}
                
print(indexArray)

But my problem is I get all of the three indexes. I just want only Native indexes (as in this case second index). (As much as I searched although it is part of other indexes too). Any help will be highly appreciated.

If you use localizedCaseInsensitiveContains, then sure, all three of three of them contain "Native". That is what "contain" means. — matt

You are filtering contains, all items contain "Native", you have to filter is equal aka compare

let indexArray = demand.indices.filter { demand[$0].localizedCaseInsensitiveCompare("Native") == .orderedSame }           
print(indexArray)

You are using the localizedCaseInsensitiveContains method, which returns everything that contains "Native" while being case-insensitive.

It sounds like your goal is to filter the array and return only values that are equal to "Native"

The previous Answer has a great solution for accomplishing this. However, here is a more simple one:

let indexArray = demand.indices.filter { demand[$0] == "Native" }
