converting data back into a string
You can use NSString's -initWithData:encoding: initializer method.
NSData *charlieSendData = [[charlieImputText stringValue] dataUsingEncoding:NSUTF8StringEncoding]NSString *charlieSendString = [[NSString alloc] initWithData:charlieSendData encoding:NSUTF8StringEncoding];
Use NSString's initWithData method:
NSString *someString = [[NSString alloc] initWithData:charlieSendData encoding:NSUTF8StringEncoding];That should do it.

NSString *string = [[NSString alloc] initWithData:dataToConvert encoding:NSUTF8StringEncoding];
