The 4 warnings are on Letter.m 2 on line 15, and 2 on line 19

	//---Test and Run Here----
	
	Letter *myLetter = [[Letter alloc] init];
	
	[myLetter setC: 'c'];
	[myLetter setD: 'd'];

OOPS - sorry about that here is the corrected Letter.h @interface section

You have two implementation sections here.   Where is the interface section?

Cheers,

Sorry about that Steve I modified it to show the correct code.

It would help when you say there is a warning that you post the warning message.

But looking at the code you are using the same name for both the instance and argument variables.
The warning is likely telling you that one is masking the other.

Use different names.
