Get only the string value from NSArray output

Question

I am storing values from Json response like

self.NameArray = self.attachmentsArray.valueForKey("filename") as! NSArray

Output:

NameArray(("Din.pdf","img.jpeg"),(),(),("41_58"))

I got this output. I need to get the array only having ("Din.pdf","img.jpeg","41_58").

How to get it using swift code?

@Mr.UB Actually now that OP has told us they have an NSArray, the linked answers would not be sufficient since OP would have to cast their NSArray to a Swift array first (screenshot). — Eric Aya

Convert NSArray to Swift Type [[String]]:

let NameArray:NSArray = [["Din.pdf","img.jpeg"], [], [], [ "41_58" ]]

let swiftArray = NameArray as! [[String]]

let flattenedArray = swiftArray.flatMap{ $0 }

If you do not want to convert it into Swift Type:

let NameArray:NSArray = [["Din.pdf","img.jpeg"], [], [], [ "41_58" ]]

let arrFiltered:NSMutableArray! = []

for arr in NameArray {
    for a in arr as! NSArray {
        arrFiltered.addObject(a)
    }
}

print(arrFiltered)
