NSFileManager.defaultManager().fileExistsAtPath returns false instead of true

问题

How is it possible?

let exists = NSFileManager.defaultManager().fileExistsAtPath(path.absoluteString)
print("exists: \(exists)") //false

This is path.absoluteString

And you can see it is there where it should be:

What is going on?

(The code in this answer has been updated for Swift 3 and later.)

Apparently your path variable is a NSURL (describing a file path). To get the path as a string, use the path property, not absoluteString:

let exists = FileManager.default.fileExists(atPath: path.path)

absoluteString returns the URL in a string format, including the file: scheme etc.

Example:

let url = URL(fileURLWithPath: "/path/to/foo.txt")

// This is what you did:
print(url.absoluteString)
// Output:    file:///path/to/foo.txt

// This is what you want:
print(url.path)
// Output:    /path/to/foo.txt

If you want to check if a path exist,you should check path

let url = NSURL(string: "balabala")

let path = url?.path
//Check path
