The file “ ” couldn’t be opened because you don’t have permission to view it

Question

I am downloading a file to a folder and I am validating that the file is indeed there in the code, but I am getting the above error. Can someone help me figure out why i dont have permissions to read this file?

let documentsURL = NSSearchPathForDirectoriesInDomains
(.DocumentDirectory, .UserDomainMask, true)[0]

let checkValidation = NSFileManager.defaultManager()

if (checkValidation.fileExistsAtPath(documentsURL))
{
    print("FILE AVAILABLE");
}
else
{
    print("FILE NOT AVAILABLE");
}

print(documentsURL)

do{
    let data = try String(contentsOfFile: documentsURL as String,
                          encoding: NSASCIIStringEncoding)
    print(data)
    
}
catch let error { print(error) }

Answer 1

Try

fileURL.startAccessingSecurityScopedResource()
//...
fileURL.stopAccessingSecurityScopedResource()

Answer 2

Your documentsURL is the address of the Documents FOLDER in your app. It is not a FILE that you can get the contents of:

/var/mobile/Containers/Data/Application/7FA4D6A9-2149-4053-BF08-22E94A00AE34/Documents
