I want to sort a dictionary in Swift. I have a dictionary like:
"A" => Array[]
"Z" => Array[]
"D" => Array[]
etc. I want it to be like
"A" => Array[]
"D" => Array[]
"Z" => Array[]
etc.
I have tried many solutions on SO but no one worked for me. I am using XCode6 Beta 5 and on it some are giving compiler error and some solutions are giving exceptions. So anyone who can post the working copy of dictionary sorting.
let dictionary = [
"A" : [1, 2],
"Z" : [3, 4],
"D" : [5, 6]
]
let sortedKeys = Array(dictionary.keys).sorted(<) // ["A", "D", "Z"]
EDIT:
The sorted array from the above code contains keys only, while values have to be retrieved from the original dictionary. However, 'Dictionary' is also a 'CollectionType' of (key, value) pairs and we can use the global 'sorted' function to get a sorted array containg both keys and values, like this:
let sortedKeysAndValues = sorted(dictionary) { $0.0 < $1.0 }
println(sortedKeysAndValues) // [(A, [1, 2]), (D, [5, 6]), (Z, [3, 4])]
EDIT2: The monthly changing Swift syntax currently prefers
let sortedKeys = Array(dictionary.keys).sort(<) // ["A", "D", "Z"]
The global sorted is deprecated.
To be clear, you cannot sort Dictionaries. But you can out put an array, which is sortable.
Swift 2.0
Updated version of Ivica M's answer:
let wordDict = [
"A" : [1, 2],
"Z" : [3, 4],
"D" : [5, 6]
]
let sortedDict = wordDict.sort { $0.0 < $1.0 }
print("\(sortedDict)") //
Swift 3
wordDict.sorted(by: { $0.0 < $1.0 })
In Swift 5, in order to sort Dictionary by KEYS
let sortedYourArray = YOURDICTIONARY.sorted( by: { $0.0 < $1.0 })
In order to sort Dictionary by VALUES
let sortedYourArray = YOURDICTIONARY.sorted( by: { $0.1 < $1.1 })
If you want to iterate over both the keys and the values in a key sorted order, this form is quite succinct
let d = [
"A" : [1, 2],
"Z" : [3, 4],
"D" : [5, 6]
]
Swift 1,2:
for (k,v) in Array(d).sorted({$0.0 < $1.0}) {
println("\(k):\(v)")
}
Swift 3+:
for (k,v) in Array(d).sorted(by: {$0.0 < $1.0}) {
println("\(k):\(v)")
}
I tried all of the above, in a nutshell all you need is
let sorted = dictionary.sorted { $0.key < $1.key }
let keysArraySorted = Array(sorted.map({ $0.key }))
let valuesArraySorted = Array(sorted.map({ $0.value }))
In swift 4 you can write it smarter:
let d = [ 1 : "hello", 2 : "bye", -1 : "foo" ]
d = [Int : String](uniqueKeysWithValues: d.sorted{ $0.key < $1.key })
Swift 4 & 5
For string keys sorting:
dictionary.keys.sorted(by: {$0.localizedStandardCompare($1) == .orderedAscending})
Example:
var dict : [String : Any] = ["10" : Any, "2" : Any, "20" : Any, "1" : Any]
dictionary.keys.sorted()
["1" : Any, "10" : Any, "2" : Any, "20" : Any]
dictionary.keys.sorted(by: {$0.localizedStandardCompare($1) == .orderedAscending})
["1" : Any, "2" : Any, "10" : Any, "20" : Any]
Swift 5
Input your dictionary that you want to sort alphabetically by keys.
// Sort inputted dictionary with keys alphabetically.
func sortWithKeys(_ dict: [String: Any]) -> [String: Any] {
let sorted = dict.sorted(by: { $0.key < $1.key })
var newDict: [String: Any] = [:]
for sortedDict in sorted {
newDict[sortedDict.key] = sortedDict.value
}
return newDict
}
dict.sorted(by: { $0.key < $1.key }) by it self returns a tuple (value, value) instead of a dictionary [value: value]. Thus, the for loop parses the tuple to return as a dictionary. That way, you put in a dictionary & get a dictionary back.
For Swift 4 the following has worked for me:
let dicNumArray = ["q":[1,2,3,4,5],"a":[2,3,4,5,5],"s":[123,123,132,43,4],"t":[00,88,66,542,321]]
let sortedDic = dicNumArray.sorted { (aDic, bDic) -> Bool in
return aDic.key < bDic.key
}
This is an elegant alternative to sorting the dictionary itself:
As of Swift 4 & 5
let sortedKeys = myDict.keys.sorted()
for key in sortedKeys {
// Ordered iteration over the dictionary
let val = myDict[key]
}
"sorted" in iOS 9 & xcode 7.3, swift 2.2 is impossible, change "sorted" to "sort", like this:
let dictionary = ["main course": 10.99, "dessert": 2.99, "salad": 5.99]
let sortedKeysAndValues = Array(dictionary).sort({ $0.0 < $1.0 })
print(sortedKeysAndValues)
//sortedKeysAndValues = ["desert": 2.99, "main course": 10.99, "salad": 5.99]
For Swift 3, the following sort returnes sorted dictionary by keys:
let unsortedDictionary = ["4": "four", "2": "two", "1": "one", "3": "three"]
let sortedDictionary = unsortedDictionary.sorted(by: { $0.0.key < $0.1.key })
print(sortedDictionary)
// ["1": "one", "2": "two", "3": "three", "4": "four"]
For Swift 3 the following has worked for me and the Swift 2 syntax has not worked:
// menu is a dictionary in this example
var menu = ["main course": 10.99, "dessert": 2.99, "salad": 5.99]
let sortedDict = menu.sorted(by: <)
// without "by:" it does not work in Swift 3
Swift 3 is sorted(by:<)
let dictionary = [
"A" : [1, 2],
"Z" : [3, 4],
"D" : [5, 6]
]
let sortedKeys = Array(dictionary.keys).sorted(by:<) // ["A", "D", "Z"]
Swift Sort Dictionary by keys
Since Dictionary[About] is based on hash function it is not possible to use a sort function as we are used to(like Array). As an alternative you are able to implement a kind of Java TreeMap/TreeSet
Easiest way is to use .sorted(by:) function. It returns an sorted Array of key/value tupples which is easy to handle
Example:
struct Person {
let name: String
let age: Int
}
struct Section {
let header: String
let rows: [Int]
}
let persons = [
Person(name: "A", age: 1),
Person(name: "B", age: 1),
Person(name: "C", age: 1),
Person(name: "A", age: 2),
Person(name: "B", age: 2),
Person(name: "C", age: 2),
Person(name: "A", age: 3),
Person(name: "B", age: 3),
Person(name: "C", age: 3),
]
//grouped
let personsGroupedByName: [String : [Person]] = Dictionary(grouping: persons, by: { $0.name })
/**

[0] = {

}
[2] = {

value = 3 values {
[0] = (name = "C", age = 1)
[1] = (name = "C", age = 2)
[2] = (name = "C", age = 3)
}
}
*/
//sort by key
let sortedPersonsGroupedByName: [Dictionary<String, [Person]>.Element] = personsGroupedByName.sorted(by: { $0.0 < $1.0 })
/**

my two cents, as all answers seem to miss we have a Dict and we do want a Dict:
var menu = ["main course": 10.99, "dessert": 2.99, "salad": 5.99]
let sortedMenu = menu.sorted(by: <) // is an ARRAY
print(type(of: sortedMenu))
let sortedDict = Dictionary( uniqueKeysWithValues: menu.sorted(by: <) )
print(type(of: sortedDict))
Above I sorted by value, by Key:
let sorted1 = menu.sorted { (kv1, kv2) in
return kv1.key < kv2.key
}
and/or apply conversion to Dict using constructor.
I am wanted to make a search on NSMUtableArray with key values to catch the hole object not just an array of values so for example my NSMUtableArray return me
{id : 1, name : x1}
{id : 2, name : x2}
{id : 3, name : x3}
{id : 4, name : y1}
{id : 5, name : y2}
if I am searching of x my code return me
{x1,x2,x3}
or I want it to return
{id : 1, name : x1}
{id : 2, name : x2}
{id : 3, name : x3}
my code is :
let arrayy = lstResults.value(forKey: "name")
let searchTest = NSPredicate(format: "SELF BEGINSWITH [c] %#", searchBar.text!)
let array = (arrayy as! NSArray).filtered(using: searchTest)
filteredTableDataName = array as NSArray
please help I tried a lot of stuff but nothing worked form me.
Instead of extracting and filtering the "name" values you can filter the array directly, using the corresponding key path instead of “SELF” in the predicate:
let array = NSArray(array: [
["id": 1, "name": "x1"], ["id": 2, "name": "x2"], ["id": 3, "name": "y3"]])
let predicate = NSPredicate(format: "name BEGINSWITH [c] %#", "x")
let filtered = array.filtered(using: predicate)
print(filtered)
Result:
[{
id = 1;
name = x1;
}, {
id = 2;
name = x2;
}]
Another option is to cast the NS(Mutable)Array to a Swift array of dictionaries, and use the filter() function:
if let a = array as? [[String: Any]] {
let filtered = a.filter {
($0["name"] as? String)?
.range(of: "x", options: [.caseInsensitive, .anchored]) != nil
}
print(filtered)
// [["id": 1, "name": x1], ["name": x2, "id": 2]]
}
NSMutableArray (or NSArray for that matter) are leftovers from the 'Objective-c' era.
For this purpose there is not real need using it or not using Swift's standard generic Array<Element> => https://developer.apple.com/documentation/swift/array
Might I consider creating a struct instead of using a dictionary:
import Foundation
struct Obj {
let id: Int
let name: String
}
let array = [
Obj(id: 1, name: "x1"),
Obj(id: 2, name: "x2"),
Obj(id: 3, name: "X3"),
Obj(id: 4, name: "y1"),
Obj(id: 5, name: "y2")
]
let filteredArray = array.filter { $0.name.localizedLowercase.hasPrefix("x") }
// filteredArray = [
// Obj(id: 1, name: "x1"),
// Obj(id: 2, name: "x2"),
// Obj(id: 3, name: "X3")
// ]
Else you would have something like this:
import Foundation
let array: [[String: Any]] = [
[ "id": 1, "name": "x1" ],
[ "id": 2, "name": "x2" ],
[ "id": 3, "name": "X3" ],
[ "id": 4, "name": "y1" ],
[ "id": 5, "name": "y2" ]
]
let filteredArray = array.filter { ($0["name"] as? String)?.localizedLowercase.hasPrefix("x") == true }
If a key is duplicated in an array, I want to combine the values of that key. For example, I have the following array.
var arrays = [
["Product":"Item0", "Price":"15"],
["Product":"Item1", "Price":"53"],
["Product":"Item2", "Price":"12"],
["Product":"Item1", "Price":"83"],
["Product":"Item0", "Price":"10"],
["Product":"Item3", "Price":"88"],
["Product":"Item0", "Price":"44"]
]
And I want to change this array like this.
[
["Product": "item0", "Price": "69"],
["Product": "item1", "Price": "136"],
["Product": "item2", "Price": "12"],
["Product": "item3", "Price": "88"]
]
What should I do?
This is the code I wrote. However, if more than two keys are duplicated, the exact value is not displayed. Could you fix a little here or give me a new way at all?
var arrays= [
["Product":"Item0", "Price":"15"],
["Product":"Item1", "Price":"53"],
["Product":"Item2", "Price":"12"],
["Product":"Item1", "Price":"83"],
["Product":"Item0", "Price":"10"],
["Product":"Item3", "Price":"88"],
["Product":"Item0", "Price":"44"]
]
var filteredArrays = [[String:String]]()
var sum : Int = 0
for i in 0..<arrayOfDicts.count {
let Product1 = arrayOfDicts[i]["Product"]
if(i == 0){
filteredArrays.append(arrayOfDicts[i])
} else {
var flag = false
for j in 0..<filteredArrays.count {
let Product2:String = filteredArrays[j]["Product"]!
if Product1 == Product2 {
sum += (Int(arrayOfDicts[i]["Price"]!)! + Int(arrayOfDicts[j]["Price"]!)!)
filteredArrays[j] = ["Product":"\(arrayOfDicts[i]["Product"]!)", "Price":"\(sum)"]
sum = 0
flag = true
}
}
if !flag {
filteredArrays.append(arrayOfDicts[i])
}
}
}
Thank you
Iterate through your products
Check if "Product" contains valid string
Extract price as Int (or float if needed). Default as zero to avoid wrong sum.
Create a dictionary with product name as key and sum the values with same key
Convert dictionary to array
var result = [String : Int]()
for product in arrays {
if let productKey = product["Product"] {
let value = Int(product["Price"] ?? "0")
if result[productKey] == nil, let value = value {
result[productKey] = value
} else if let value = value {
result[productKey]! += value
}
}
}
let newArray = result.map {["Product":$0, "Price": $1]}
Just for fun, not for the faint-hearted, using Swift 4 new method reduce(into:) and Dictionary Key-based subscript with default value:
let result = arrays.reduce(into: [String : Int]()) {
$0[$1["Product"] ?? "", default: 0] += Int($1["Price"] ?? "") ?? 0 }
.map { ["Product": $0, "Price": $1] }
print(result)
"[["Product": "Item0", "Price": 69], ["Product": "Item2", "Price":
12], ["Product": "Item1", "Price": 136], ["Product": "Item3", "Price":
88]]\n"
{ length = 30, contents = "something", count = 32.3 }
I need exact output in this bracket { } not in() or []
var array:Array<Any> = Array<Any>();
array.append(NSDictionary(object: singleItem.name, forKey: "name" as NSCopying));
array.append(NSDictionary(object: singleItem.planned_revenue, forKey: "planned_revenue" as NSCopying));
array.append(NSDictionary(object: singleItem.phone, forKey: "phone" as NSCopying));
array.append(NSDictionary(object: singleItem.description, forKey: "description" as NSCopying));
array.append(NSDictionary(object: singleItem.email_from, forKey: "email_from" as NSCopying));
array.append(NSDictionary(object: singleItem.probability, forKey: "probability" as NSCopying));
output
[{
name = "this is another";
}, {
"planned_revenue" = "0.0";
}, {
phone = "";
}, {
description = "Internal Notes";
}, {
"email_from" = "thomas.passot#agrolait.example.com";
}, {
probability = "20.0";
}]
I need like
[{ name = "this is another", "planned_revenue" = "0.0", phone = "", description = "Internal Notes", ..... }]
First, you need a dictionary, not an array of dictionaries. Using Swift, you can use Dictionary instead of NSDictionary (Dictionary<String, Any> or [String: Any]):
let dict: [String: Any] = [
"name": singleItem.name,
"planned_revenue": singleItem.planned_revenue,
"phone": singleItem.phone,
"description": singleItem.description,
"email_from": singleItem.email_from,
"probability": singleItem.probability
]
// If you need a NSDictionary, you can cast it
let nsDict = dict as NSDictionary
Take a look at Collection Types in the Swift guide and the Dictionary class reference for more information.

my two cents, as all answers seem to miss we have a Dict and we do want a Dict:
var menu = ["main course": 10.99, "dessert": 2.99, "salad": 5.99]
let sortedMenu = menu.sorted(by: <) // is an ARRAY
print(type(of: sortedMenu))
let sortedDict = Dictionary( uniqueKeysWithValues: menu.sorted(by: <) )
print(type(of: sortedDict))
Above I sorted by value, by Key:
let sorted1 = menu.sorted { (kv1, kv2) in
return kv1.key < kv2.key
}
and/or apply conversion to Dict using constructor.
