I want to quickly check to see if a file exists in my iPhone app's Documents directory (or any path for that matter). I can enumerate through the directory's files, or I can try to open a specific file. What's the fastest way? I just need to know if the file is there or if it does not exist.

To check if a file exists, you pass the file path to the exists() function from the os. path standard library. If the file exists, the exists() function returns True . Otherwise, it returns False .
The exists() function is a part of the File class in Java. This function determines whether the is a file or directory denoted by the abstract filename exists or not. The function returns true if the abstract file path exists or else returns false.
To check whether a Path object exists independently of whether is it a file or directory, use my_path. exists() .
In Python, you can check whether certain files or directories exist using the isfile() and isdir() methods, respectively. However, if you use isfile() to check if a certain directory exists, the method will return False. Likewise, if you use if isdir() to check whether a certain file exists, the method returns False.
Swift v3:
let fileExists = FileManager.default.fileExists(atPath: somePath)
Thanks to Nikolay Suvandzhiev.
Objective-C (Original):
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:somePath];
