Is there a way to pretty print Swift dictionaries to the console?

Question

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

prints out the following on the console:

{     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) 

prints out the following on the console:

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

Is there a way in Swift to get it to pretty print dictionaries where each key-value pair occupies a new line?

Answer 1

po solution

For those of you want to see Dictionary as JSON with out escape sequence in console, here is a simple way to do that

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

Casting a dictionary to 'AnyObject' was the simplest solution for me:

let dictionary = ["a":"b",                   "c":"d",                   "e":"f"] print("This is the console output: \(dictionary as AnyObject)") 

This is easier to read for me than the dump option, but note it won't give you the total number of key-values.
