Answer 1

from NSString

- (unichar)characterAtIndex:(NSUInteger)index

Is the method. It returns a unichar, not an NSString. You are declaring your variable is an NSString pointer but a unichar is stored as an integer behind the scenes.

Your line should be

unichar character = [string charachterAtIndex:random];

as a side note you can’t call your variable char as its a reserved keyword in C.
