Swift: Reading a plist from MainBundle and writing directly to Documents fails

Question

Take the following file, named Permissions.plist:

Answer 1

This is wrong:

guard let docsURL = NSURL(string: docsString) else { ... }

To create an NSURL from a file path, use

let docsURL = NSURL(fileURLWithPath: docsString)

Conversely, you cannot use string interpolation to create a file path from an NSURL:

let plistString = "\(plistURL)"

Use the .path method instead:

let plistPath = plistURL.path!

Or better, use the writeToURL() method to write your dictionary, then you don't have to convert the URL to a path.
