How to check if a file exists in the Documents directory in Swift?

I am using [ .writeFilePath ] method to save an image into the Documents

Answer 1

It's pretty user friendly. Just work with NSFileManager's defaultManager singleton and then use the fileExistsAtPath() method, which simply takes a string as an argument, and returns a Bool, allowing it to be placed directly in the if statement.

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let documentDirectory = paths[0] as! String
let myFilePath = documentDirectory.stringByAppendingPathComponent("nameOfMyFile")

let manager = NSFileManager.defaultManager()
if (manager.fileExistsAtPath(myFilePath)) {
    // it's here!!
}

Note that the downcast to String isn't necessary in Swift 2.
