The deprecated way:
NSArray *fileList = [manager directoryContentsAtPath:productDirectory];

replace directoryContentsAtPath with contentsOfDirectoryAtPath & you must also add error:nil

The new hotness:
NSArray *fileList = [manager contentsOfDirectoryAtPath:productDirectory error:nil];

NSString *contents = [NSString stringWithContentsOfFile:fullpath];

After doing a bit of Googling I found the solution.

Replace NSString *contents = [NSString stringWithContentsOfFile:fullpath]; with:

NSString *contents = [NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];[NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];

(Side Note: Ever since I began coding my vocabulary has expanded. Now I get to use words like Redacted and Deprecated Thanks Apple!)
