How do I write a string to a file?

I have a .txt file with a small password in it. I would like to change that file's text. How can I do that? I can get the file's text using :

 NSString *passWord = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"password" ofType:@"txt"] encoding:NSUTF8StringEncoding error:NULL];

But I can't seem to find a way to replace the contents of the file with a string.

The way to do this is to remove old file and create new one. Removing existing file

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"myFile.txt"];

NSFileManager *fileManager = [NSFileManager defaultManager];

if([fileManager fileExistsAtPath:filePath])
{
    [fileManager removeItemAtPath:filePath error:&error];
}

To crate new file with your new password write password data while creating file as:

[createFileAtPath:path contents:[NSData data] attributes:nil]
