ios - 有没有办法将 Swift 词典漂亮地打印到控制台？

Question

NSDictionary *dictionary = @{@"A" : @"alfa",
                             @"B" : @"bravo",
                             @"C" : @"charlie",
                             @"D" : @"delta",
                             @"E" : @"echo",
                             @"F" : @"foxtrot"};
NSLog(@"%@", dictionary.description);

在控制台打印出以下内容:

{
    A = alfa;
    B = bravo;
    C = charlie;
    D = delta;
    E = echo;
    F = foxtrot;
}

let dictionary: [String : String] = ["A" : "alfa",
                                     "B" : "bravo",
                                     "C" : "charlie",
                                     "D" : "delta",
                                     "E" : "echo",
                                     "F" : "foxtrot"];
print(dictionary)

在控制台打印出以下内容:

["B": "bravo", "A": "alfa", "F": "foxtrot", "C": "charlie", "D": "delta", "E": "echo"]

在 Swift 中有没有一种方法可以将其放入漂亮的打印字典中，其中每个键值对都占一个新行？

po解决方案

对于那些希望在控制台中将字典视为不带转义序列的 JSON 的人，这里有一个简单的方法:

(lldb) p print(String(data: try! JSONSerialization.data(withJSONObject: object, options: .prettyPrinted), encoding: .utf8)!)
