Answer 1

Swift 4

I will tell you the steps to save a photo from Document] -> [Photos Library] in the easiest way that is using UIImageWriteToSavedPhotosAlbum() function of UIKit

Step 1:

• Ask for permission to access Photos Library “Privacy - Photo Library Additions Usage Description”
• Refer to this link for more details https://developer.apple.com/documentation/photokit/delivering_an_enhanced_privacy_experience_in_your_photos_app

Step 2:

• Get the [image data] you want to copy with Data(contentsOf: URL)
• You can learn how to get the [Url] of the file in the [Document], do a search because this job has a lot of articles and is also very easy to do. Dont worried

Step 3:

• Create a [UIImage] from the [Data] you got above

Step 4:

• Pass the [UIImage] present in step 3 to the first parameter of UIImageWriteToSavedPhotosAlbum(). All remaining parameters can be set to nil.
