I am trying to initialize a String from the content accessible by a URL:
actualresponse.response = String(contentsOfURL: url, usedEncoding: NSUTF8StringEncoding) I get the following error thrown, pointing at the usedEncoding:
Cannot convert value of type 'UInt' to expected argument type 'UnsafeMutablePointer'
Can anyone tell me why this error is thrown and how I can fix it?
There are two similar but different methods which can be mistaken.
The usual method is
init(contentsOfURL url: NSURL, encoding enc: UInt) throws The encoding parameter takes an NSStringEncoding value to specify the encoding, for example
let string = try? String(contentsOfURL:url, encoding:NSUTF8StringEncoding) The second method retrieves the encoding from the file by passing a pointer as usedEncoding parameter
init(contentsOfURL url: NSURL, usedEncoding enc: UnsafeMutablePointer<UInt>) throws The documentation says:
Upon return, if url is read successfully, contains the encoding used to interpret the data.
That means you have to pass a pointer which will contain the determined encoding of the file.
var encoding : NSStringEncoding = 0 let string = try? String(contentsOfURL:url, usedEncoding:&encoding)
