What happened to the archiving stuff in Swift 2.0? I can't use stringByAppendingPathComponent any more?

Real problem. Just updated my Xcode and now it's telling me I need to use URLByAppendingPathComponent on NSURL instead of stringByAppendingPathComponent.

As my users progress through my app I am keeping track of their progress by archiving their progress and calling back to it as I need it.

The basic idea of the code is: let filemgr = NSFileManager.defaultManager() let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) let docsDir = dirPaths[0] as? String

    dataFilePathDictionary = docsDir!.stringByAppendingPathComponent(dictionaryArchive)

if filemgr.fileExistsAtPath(dataFilePathDictionary!){ print("Loading the progressDictionary") userProgressDictionary = NSKeyedUnarchiver.unarchiveObjectWithFile(dataFilePathDictionary!) as! [Int: Int] }else { print("User Progress Dictionary Didn't Exist yet at File Path: (dataFilePathDictionary!)") userProgressDictionary = [ 0:0, 1: 0, 2:0, 3:0, 4:0, 5:0, 6:0, 7:0, 8:0, 9:0, 10:0, 11:0, 12:0, 13:0, 14:0, 15:0, 16:0, 17:0] }

I was able to archive anything like a Dictionary, string, int, or what ever I needed. I sunk if I can't figure this out.

And yes, this exact code has been working for months. That is before I updated.

The answer: Remove the ? after the "as" and change the "String" to "NSString" Doing that makes everything work.
