How to make phone call in iOS 10 using Swift?

Question

I want my app to be able to call a certain number when a button is clicked. I've tried to google it but there doesn't seem to have one for iOS 10 so far (where openURL is gone). Can someone put an example for me on how to do so? For instance like:

@IBAction func callPoliceButton(_ sender: UIButton) {
    // Call the local Police department
}

Thank! I tried the same exact code however, when I change the google.com to "tel://120390129391824812988238197", nothing happened when I clicked on the button. Is there something I am missing? — user3175707, Oct 18 '16 at 04:13
I was expecting it to have some pop-up and say "call 120390129391824812988238197 ?" — user3175707, Oct 18 '16 at 04:13

You can call like this:

 if let url = URL(string: "tel://\(number)") {
     UIApplication.shared.openURL(url)
 }

For Swift 3+, you can use like

guard let number = URL(string: "tel://" + number) else { return }
UIApplication.shared.open(number)

OR

UIApplication.shared.open(number, options: [:], completionHandler: nil)

Make sure you've scrubbed your phone number string to remove any instances of (, ), -, or space.

The `openURL` method is deprecated in iOS 10. The OP is asking what the replacement is. – rmaddy Oct 17 '16 at 05:38

`options` and `completionHandler` have default values so you can actually just do `UIApplication.shared.open(number)` – Paolo May 21 '17 at 15:46
@Paolo Yes that's true. – Parth Adroja May 22 '17 at 04:45
what be the number in above @ParthAdroja – Dilip Tiwari Sep 12 '17 at 04:56
@DilipTiwari Number will be String. – Parth Adroja Sep 12 '17 at 06:18
Will it be empty right @ParthAdroja – Dilip Tiwari Sep 12 '17 at 06:24
@DilipTiwari No it wouldn't be empty. It will be like "tel://+911111111" – Parth Adroja Sep 12 '17 at 07:51
ok i got it @ParthAdroja – Dilip Tiwari Sep 12 '17 at 07:57
i can also pass string from json to this telephone string @ParthAdroja – Dilip Tiwari Sep 12 '17 at 07:58
@DilipTiwari Yes – Parth Adroja Sep 12 '17 at 08:56
thanks @ParthAdroja – Dilip Tiwari Sep 12 '17 at 09:03
Is there a way to get notified when the call has ended? – Srdjan Mar 20 '19 at 15:02

Make a call with phone number validation

Tested on:

Swift 5.2, Xcode 11.4 (11E146)

Solution

// MARK: DataDetector

class DataDetector {

    private class func _find(all type: NSTextCheckingResult.CheckingType,
                             in string: String, iterationClosure: (String) -> Bool) {
        guard let detector = try? NSDataDetector(types: type.rawValue) else { return }
        let range = NSRange(string.startIndex ..< string.endIndex, in: string)
        let matches = detector.matches(in: string, options: [], range: range)
        loop: for match in matches {
            for i in 0 ..< match.numberOfRanges {
                let nsrange = match.range(at: i)
                let startIndex = string.index(string.startIndex, offsetBy: nsrange.lowerBound)
                let endIndex = string.index(string.startIndex, offsetBy: nsrange.upperBound)
                let range = startIndex..<endIndex
                guard iterationClosure(String(string[range])) else { break loop }
            }
        }
    }

    class func find(all type: NSTextCheckingResult.CheckingType, in string: String) -> [String] {
        var results = [String]()
        _find(all: type, in: string) {
            results.append($0)
            return true
        }
        return results
    }

    class func first(type: NSTextCheckingResult.CheckingType, in string: String) -> String? {
        var result: String?
        _find(all: type, in: string) {
            result = $0
            return false
        }
        return result
    }
}

// MARK: PhoneNumber

struct PhoneNumber {
    private(set) var number: String
    init?(extractFrom string: String) {
        guard let phoneNumber = PhoneNumber.first(in: string) else { return nil }
        self = phoneNumber
    }

    private init (string: String) { self.number = string }

    func makeACall() {
        guard let url = URL(string: "tel://\(number.onlyDigits())"),
            UIApplication.shared.canOpenURL(url) else { return }
        if #available(iOS 10, *) {
            UIApplication.shared.open(url)
        } else {
            UIApplication.shared.openURL(url)
        }
    }

    static func extractAll(from string: String) -> [PhoneNumber] {
        DataDetector.find(all: .phoneNumber, in: string)
            .compactMap {  PhoneNumber(string: $0) }
    }

    static func first(in string: String) -> PhoneNumber? {
        guard let phoneNumberString = DataDetector.first(type: .phoneNumber, in: string) else { return nil }
        return PhoneNumber(string: phoneNumberString)
    }
}

extension PhoneNumber: CustomStringConvertible { var description: String { number } }

// MARK: String extension

extension String {

    // MARK: Get remove all characters exept numbers

    func onlyDigits() -> String {
        let filtredUnicodeScalars = unicodeScalars.filter { CharacterSet.decimalDigits.contains($0) }
        return String(String.UnicodeScalarView(filtredUnicodeScalars))
    }

    var detectedPhoneNumbers: [PhoneNumber] { PhoneNumber.extractAll(from: self) }
    var detectedFirstPhoneNumber: PhoneNumber? { PhoneNumber.first(in: self) }
}

Usage

PhoneNumber(extractFrom: "+1-(800)-123-4567")?.makeACall()

PhoneNumber.extractAll(from: "+1-(800)-123-4567 bla bla 1(617)111-22-33").last?.makeACall()

PhoneNumber.first(in: "+1-(800)-123-4567 bla bla 1(617)111-22-33")?.makeACall()

"+1-(800)-123-4567 bla bla 1(617)111-22-33".detectedPhoneNumbers[1].makeACall()
"+1-(800)-123-4567 bla bla 1(617)111-22-33".detectedFirstPhoneNumber?.makeACall()

I walked straight into upvoting with the fancy answer and bright colours/emojis... and then... ❌ +44 1838 300284 | 441838300284 | [not a phone number]. This is not working for me and returns false for everything — paul_f, Jun 22 '19 at 15:43
@paul_f did you tried to run the code on sample? Is is not working too? — Vasily Bodnarchuk, Jun 22 '19 at 15:55
Test works fine, whatever it is about my test case it does not work at all: "+44 1838 300284" for example. I think the spacing of the numbers is the issue. It's a common spacing here. — paul_f, Jun 22 '19 at 16:05
@VasilyBodnarchuk I actually wanted to upvote the answer but accidentally hit on the downvote button. — Jabbar, Dec 23 '19 at 13:13
@Jabbar thank you for the comment) because downvote for me means that something wrong with my code and I have to check it again. Glad to help! — Vasily Bodnarchuk, Dec 23 '19 at 13:17
@VasilyBodnarchuk No, there is nothing wrong with the code. It works perfectly. I just accidentally hit the downvote button. — Jabbar, Dec 23 '19 at 14:27
@VasilyBodnarchuk, "phone:+1(617)111-22-33!".makeACall() is not working for me in Xcode 11.4, Can you help me out. — Sivabalaa Jothibose, Apr 15 '20 at 14:58
@SivabalaaJothibose Hello there! Did you tried to simulate the code on a real device? — Vasily Bodnarchuk, Apr 15 '20 at 15:09
@VasilyBodnarchuk Hi, In Real device. `guard isValid(regex: .phone)` is giving `false`. — Sivabalaa Jothibose, Apr 15 '20 at 15:10

In Swift 4.2

func dialNumber(number : String) {

 if let url = URL(string: "tel://\(number)"),
   UIApplication.shared.canOpenURL(url) {
      if #available(iOS 10, *) {
        UIApplication.shared.open(url, options: [:], completionHandler:nil)
       } else {
           UIApplication.shared.openURL(url)
       }
   } else {
            // add error message here 
   }
}

Call this like below

dialNumber(number: "+921111111222")

Hope this help.

Updated for Swift 3:

used below simple lines of code, if you want to make a phone call:

// function defination:

func makeAPhoneCall()  {
    let url: NSURL = URL(string: "TEL://1234567890")! as NSURL
    UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
}

// function call: [Used anywhere in your code]

self.makeAPhoneCall()

Note: Please run the app on a real device because it won't work on the simulator.

By mistake my answer was misplaced, please checkout this one: You can use this:

guard let url = URL(string: "tel://\(yourNumber)") else {
return //be safe
}

if #available(iOS 10.0, *) {
UIApplication.shared.open(url)
} else {
UIApplication.shared.openURL(url)
}

We need to check whether we're on iOS 10 or later As 'openURL' was deprecated in iOS 10.0
