How to add NSMutableDictionary values in NSMutableArray

Question

I have one NSMutableDictionary with different keys and values. All key values I need to save in NSMutableArray in Swift3.

Here is my NSMutableDictionary :

  {
    92 =     (
        "<Group.VideoRange: 0x6040003a09a0>",
        "<Group.VideoRange: 0x6040003a0c40>"
    );
    93 =     (
        "<Group.VideoRange: 0x6040003a0540>"
    );
  }

Note: Here 92 and 93 is my dictionary keys.

Below is my code to add dictionary all values in my array.

for value in videoRangeDic.allValues{

    arrVideoRange.add(value)
}

As an output, I am getting below array value :

(
        (
        "<Group.VideoRange: 0x6040003a0540>"
    ),
        (
        "<Group.VideoRange: 0x6040003a09a0>",
        "<Group.VideoRange: 0x6040003a0c40>"
    )
)

Instead, I want my output should be like :

    (
        "<Group.VideoRange: 0x6040003a0540>",
        "<Group.VideoRange: 0x6040003a09a0>",
        "<Group.VideoRange: 0x6040003a0c40>"
    )

The reason is dictionary is saving values in array like (), So I just need to remove this array. Can anyone please help me to solve my problem without creating any new array. Thank you!

You can get all the value of your dic by single line code

print("values array : \(videoRangeDic.map{$0.value}.flatMap{$0})")

Thank you @iPatel for your time, I tried above solution. I'm not getting my array output in single (). – user2786 Nov 23 '17 at 06:39

Yes because you are using objective c array and dictionary thats why – iPatel Nov 23 '17 at 06:42
Is there any way to convert objective c array and dictionary into swift? – user2786 Nov 23 '17 at 06:48

If your arrVideoRange is NSMutableArray like this

var arrVideoRange : NSMutableArray = []

then try this

for value in videoRangeDic.allValues{

    arrVideoRange.addObjects(from: value as [Any])

}

You can use flatMap to flatten the array of dictionaries to array

let array = groupDicts.flatMap { $0.values.joined() }

or

let newArray = Array(dicts.lazy.flatMap { $0.values }.joined())
