SwiftFiles

Save, Load and Delete files from within a Swift playground

Usage

List file NSURLs in a given location

 do {
    if let files = try FileList.allFilesAndFolders(inDirectory: NSSearchPathDirectory.CachesDirectory, subdirectory: "Data") {
    for file in files {
        print("Filename:\(file.lastPathComponent!) NSURL:\(file)")
        }
    }
    else {
        print("failed to find given location")
    }
  }
catch  {
    print("error occurred")
}

Save a string to a file

FileSave.saveStringToTemporaryDirectory("hello World", path: "myString.txt", subdirectory: "")

Save, load and delete

FileSave.saveString("hello world", directory: NSSearchPathDirectory.DocumentDirectory, path: "myString.txt", subdirectory: "MyFiles")
FileLoad.loadString("myString.txt", directory: NSSearchPathDirectory.DocumentDirectory, subdirectory: "MyFiles", encoding: NSUTF8StringEncoding)
FileDelete.deleteFile("myString.txt", directory: NSSearchPathDirectory.DocumentDirectory, subdirectory: "MyFiles")
FileLoad.loadString("myString.txt", directory: NSSearchPathDirectory.DocumentDirectory, subdirectory: "MyFiles", encoding: NSUTF8StringEncoding) // returns nil file is deleted

Save and load data

let data = "Hello Swift".dataUsingEncoding(NSUTF8StringEncoding)!
FileSave.saveData(data, directory: NSSearchPathDirectory.CachesDirectory, path: "myFile.txt", subdirectory: "Data")
FileLoad.loadData("myFile.txt", directory: NSSearchPathDirectory.CachesDirectory, subdirectory: "Data") == data // true

Find file locations on your system

// find out the location of your files to use in Finder -> Go -> Go to Directory dialogue box
FileDirectory.applicationDirectory(NSSearchPathDirectory.DocumentDirectory)
FileDirectory.applicationTemporaryDirectory()

Note that the majority of the methods are throwing methods and so require do/try/catch. See the playground for examples.
