Copying files from bundle to Libraries folder (IOS10, Swift3, xcode 8.2)

Question

Here is my code for copying the folder from bundle to libraries.

    let library = FileManager.default.urls(for: .libraryDirectory, in: .userDomainMask)[0]
    let bundle = Bundle.main.path(forResource: "MYFOLDER", ofType: "")!

    let fileManager = FileManager.default
    do
    {
        try fileManager.copyItem(atPath: bundle, toPath: library.path)
        print("NO CATCH")
    }
    catch
    {
            print(error)
    }

I get this error:

Error Domain=NSCocoaErrorDomain Code=516 "“MYFOLDER” couldn’t be copied to “CBE6D212-8827-423B-AEC8-6830EED0EC5C” because an item with the same name already exists."

**BUT I CHECKED IT DOES NOT EXIST IN THE LIBRARY FOLDER*

Answer 1

As per your error, file is already existing. try this code and check

  let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
let url = NSURL(fileURLWithPath: path)
let filePath = url.appendingPathComponent("NewFolder")?.path
let fileManager = FileManager.default
if fileManager.fileExists(atPath: filePath!) {
    print("FILE AVAILABLE")
} else {
    print("FILE NOT AVAILABLE")
}
