Unichars are basically integers, so the signature of the method is wrong.
The flipside is that initWithCharacters expects a pointer to the characters,
so you have to use the & operand to convert it.

Try the following:

- (id)initWithSymbol:(unichar )aSymbol
{
    if ( self = [super init] )
    {           
        symbol = aSymbol;
        symbolString  = [[NSString alloc] initWithCharacters: &symbol
length: 1];
    }
    
    return self;
}
