How is it possible?

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

    (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
