如何从String Value将NSString转换为ASCII值

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSString *string = @"Hello World!";
        NSInteger asciiValue = [string asciiValue];
        NSLog(@"ASCII Value: %li", asciiValue);
    }
    return 0;
}

import Foundation

let string = "Hello World!"
let asciiValue = Int(string.asciiValue)
print("ASCII Value: \(asciiValue)")
