ios - What's a quick way to test to see a file exists?

Question

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.

Swift v3:

let fileExists = FileManager.default.fileExists(atPath: somePath)

Thanks to Nikolay Suvandzhiev.

Objective-C (Original):

BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:somePath];
