Sorting of an array alphabetically in swift - ios

Question

I am new to swift.I am trying one sample app in which I need to implement the sorting of an array in alphabetical order.I getting the json data and I am adding the titles in the array.Now i would like to sort that alphabetically.Here is my code .....
func updateSearchResults(data: NSData?)
{
do
{
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments)
if let blogs: NSArray = json["results"] as? [AnyObject] {
print(blogs)
for blog in blogs {
if let name = blog["original_title"] as? String {
names.addObject(name)
}
}
print(names)
**let sortedArray = sorted(names, {
(str1: String, str2: String) -> Bool in
return str1.toInt() < str2.toInt()** // Here I am getting the Error Message
})
}
}
catch {
print("error serializing JSON: \(error)")
}
}
The error message I am getting is "Cannot invoke 'sorted' with an argument list of type '(NSMutableArray, (String, String) -> Bool)'"
I tried a lot to achieve this but I didn't find the solution.
Can anyone help me to resolve this issue.
Thanks In Advance.

Answer 1

First convert NSMutableArray to the Array by using below line of code.
let swiftArray = mutableArray as AnyObject as! [String]
Use below line of code to sort the Array.
var sortedArray = names.sorted { $0.localizedCaseInsensitiveCompare($1) == NSComparisonResult.OrderedAscending }
Check below link for sort Closures.
https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/Closures.html
Update for Swift 3.0
var sortedArray = swiftArray.sorted { $0.localizedCaseInsensitiveCompare($1) == ComparisonResult.orderedAscending }

Answer 2

Use this simple code of line to sort ur array
let sortedNames = names.sort { $0.name < $1.name }
For Swift 4 you can use only this
let sortedNames = names.sorted(by: <)

Answer 3

Swift4
var names = [ "Alpha", "alpha", "bravo", "beta"]
var sortedNames = names.sorted { $0.localizedCaseInsensitiveCompare($1) == ComparisonResult.orderedAscending }
print(sortedNames) //Logs ["Alpha", "alpha","beta", "bravo"]

Answer 4

Swift 4(working code)
JSON response -> Stored in aryNameList
"DATA": [
{
email = "iosworker#gmail.com";
firstname = Harvey
},
{
email = "poonam#openxcell.com";
firstname = poonam
},
{
email = "t#t.com";
firstname = rahul
},
{
email = "android.testapps#gmail.com";
firstname = Chulbulx
},
{
email = "t#t2.com";
firstname = rahul
},
{
email = "jaystevens32#gmail.com";
firstname = Jay
},
{
email = "royronald47#gmail.com";
firstname = Roy
},
{
email = "regmanjones#hotmail.com";
firstname = Regan
},
{
email = "jd#gmail.com";
firstname = Jaydip
}
]
Code
self.aryNameList = self.aryNameList.sorted(by: { (Obj1, Obj2) -> Bool in
let Obj1_Name = Obj1.firstname ?? ""
let Obj2_Name = Obj2.firstname ?? ""
return (Obj1_Name.localizedCaseInsensitiveCompare(Obj2_Name) == .orderedAscending)
})
working every case (for ex: lowerCase, upperCase..)

Answer 5

For an array of objects:
items = items.sorted(by: { (item1, item2) -> Bool in
return item1.product.name.compare(item2.product.name) == ComparisonResult.orderedAscending
})

Answer 6

Try this one
var names = [ "Alpha", "alpha", "bravo"]
var sortedNames = names.sort { $0.localizedCaseInsensitiveCompare($1) == NSComparisonResult.OrderedAscending }
print(sortedNames) //Logs ["Alpha", "alpha", "bravo"]

Answer 7

Swift 3 solution:
let yourStringArray = [ "beTA", "ALPha", "Beta", "Alpha"]
var sortedArray = yourStringArray.sorted()
// Result will be ["ALPha", "Alpha", "Beta", "beTA"]
