Save, Load and Delete files from within a Swift playground
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.
