[SOLVED] The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data

I have added NSPhotoLibraryAddUsageDescription as well as NSPhotoLibraryUsageDescription in info.plist file of my project. While trying to create album or add image to photo library following error is coming

This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.

I have tried some swift library like PhotosHelper.as well to do that but still I am facing same Issue

Following is code that I am following

import UIKit
import Photos

class PhotoLibraryManager
{


private class func fetchAlbumWithName(albumName:String)->PHAssetCollection?
{
    let fetchPredicate = PHFetchOptions()
    fetchPredicate.predicate = NSPredicate(format: "title == '" + albumName + "'")
    let fetchResult = PHAssetCollection.fetchAssetCollections(with: PHAssetCollectionType.album, subtype: PHAssetCollectionSubtype.albumRegular, options: fetchPredicate)
    return fetchResult.firstObject
}

/**
 This function requests for authorization to use the photo gallery and adds the image in the album both of which are specified.If the album does not exist it creates a new one and adds the image in that
 - Parameters:
 - image:The image to be inserted
 - albumName:The name of the album in which the image is to be inserted
 */


class func saveImageToPhone(image:UIImage,albumName:String)
{
    PHPhotoLibrary.requestAuthorization({(status:PHAuthorizationStatus)->Void in
        switch status
        {
        case PHAuthorizationStatus.authorized:
            insertImageAfterAuthorization(image: image,albumName: albumName)
        default:
            print("Unable To Access Photo Library")
        }
    })
}

/**
 This function fetches the specified album from the photo library if present or creates a new one
 - Parameters:
 - image:The image to be inserted
 - albumName:The name of the album in which the image is to be inserted
 */


private class func insertImageAfterAuthorization(image:UIImage,albumName:String)
{
    let album = fetchAlbumWithName(albumName: albumName)
    guard let albumToBeInserted = album else{
        print("Creating A New Album \(albumName)")
        PHPhotoLibrary.shared().performChanges({
            PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: albumName)
        }, completionHandler: {(success:Bool,error:Error?)->Void in
            guard let errorObj = error else{
                let album = fetchAlbumWithName(albumName: albumName)
                guard let createdAlbum = album else{
                    print("Album Not Created")
                    return
                }
                addImageIntoAlbum(image: image,album: createdAlbum)
                return
            }
            print(errorObj.localizedDescription)
            return
        })
        return
    }
    addImageIntoAlbum(image: image,album: albumToBeInserted)
}

/**
 This function adds an image into the album specifed
 - Parameters:
 - image:The image to be added
 - album:The album in which the image is to inserted
 */

private class func addImageIntoAlbum(image:UIImage,album:PHAssetCollection)
{
    PHPhotoLibrary.shared().performChanges({
        let imgCreationRequest = PHAssetChangeRequest.creationRequestForAsset(from: image)
        print(imgCreationRequest)
        let albumRequest = PHAssetCollectionChangeRequest(for: album)
        guard let albumSpecificationRequest = albumRequest , let placeholderObjForImg = imgCreationRequest.placeholderForCreatedAsset else{
            print("Image Could Not Be Added")
            return
        }
        let arrAlbumSpecificationRequest:NSArray = [placeholderObjForImg]
        albumSpecificationRequest.addAssets(arrAlbumSpecificationRequest)
        //            albumSpecificationRequest.addAssets([placeholderObjForImg])
    }, completionHandler: {(success:Bool,error:Error?)->Void in
        guard let errorObj = error else{
            return
        }
        print(errorObj.localizedDescription)
    })
}

}

Here is my info.plist
