SwiftUI Version

Add in Info.plist

First, you have to modify Info.plist to list instagram and facebook with LSApplicationQueriesSchemes. Simply open Info.plist as a Source Code, and paste this:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>instagram</string>
    <string>fb</string>
</array>

When you want to open the Facebook App and direct to a Facebook-Page, use the Page-ID. Here is a Link, where you could find them: https://www.facebook.com/help/1503421039731588

Schemes

fb://profile – Open Facebook app to the user’s profile OR pages

fb://friends – Open Facebook app to the friends list

fb://notifications – Open Facebook app to the notifications list (NOTE: there appears to be a bug with this URL. The Notifications page opens. However, it’s not possible to navigate to anywhere else in the Facebook app)

fb://feed – Open Facebook app to the News Feed

fb://events – Open Facebook app to the Events page

fb://requests – Open Facebook app to the Requests list

fb://notes – Open Facebook app to the Notes page

fb://albums – Open Facebook app to Photo Albums list Source: https://stackoverflow.com/a/10416399/8642838

SwiftUI-Code Version

    Button(action: {
        let url = URL(string: "fb://profile/<PAGE_ID>")!
        let application = UIApplication.shared
        // Check if the facebook App is installed
        if application.canOpenURL(url) {
            application.open(url)
        } else {
            // If Facebook App is not installed, open Safari with Facebook Link
            application.open(URL(string: "https://de-de.facebook.com/apple")!)
        }
    }, label: {
        Text("Facebook")

Take a look at these links, it can help you:

Open a facebook link by native Facebook app on iOS

Otherwise, there is a quick example with Instagram for opening a specific profile (nickname: johndoe) here:

var instagramHooks = "instagram://user?username=johndoe"
var instagramUrl = NSURL(string: instagramHooks)
if UIApplication.sharedApplication().canOpenURL(instagramUrl!) {  
  UIApplication.sharedApplication().openURL(instagramUrl!)
} else {
  //redirect to safari because the user doesn't have Instagram
  UIApplication.sharedApplication().openURL(NSURL(string: "http://instagram.com/")!)
}

Answer 4

In swift 3;

First you should add this on your Info.plist

Than you can use this code;

    let instagramUrl = URL(string: "instagram://app")
    UIApplication.shared.canOpenURL(instagramUrl!)
    UIApplication.shared.open(instagramUrl!, options: [:], completionHandler: nil)

Answer 5

In swift 4:

Just change appURL and webURL :

twitter://user?screen_name=\(screenName)

instagram://user?screen_name=\(screenName)

facebook://user?screen_name=\(screenName)

• 'openURL' was deprecated in iOS 10.0:

let screenName =  "imrankst1221"
    let appURL = NSURL(string: "instagram://user?screen_name=\(screenName)")!
    let webURL = NSURL(string: "https://twitter.com/\(screenName)")!

    if UIApplication.shared.canOpenURL(appURL as URL) {
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(appURL as URL, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(appURL as URL)
        }
    } else {
        //redirect to safari because the user doesn't have Instagram
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(webURL as URL, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(webURL as URL)
        }
    }

Answer 6

Update for Swift 4 and iOS 10+

OK, there are two easy steps to achieve this in Swift 3:

First, you have to modify Info.plist to list instagram and facebook with LSApplicationQueriesSchemes. Simply open Info.plist as a Source Code, and paste this:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>instagram</string>
    <string>fb</string>
</array>

After that, you can open instagram and facebook apps by using instagram:// and fb://. Here is a complete code for instagram and you can do the same for facebook, you can link this code to any button you have as an Action:

@IBAction func InstagramAction() {

    let Username =  "instagram" // Your Instagram Username here
    let appURL = URL(string: "instagram://user?username=\(Username)")!
    let application = UIApplication.shared

    if application.canOpenURL(appURL) {
        application.open(appURL)
    } else {
        // if Instagram app is not installed, open URL inside Safari
        let webURL = URL(string: "https://instagram.com/\(Username)")!
        application.open(webURL)
    }

}

For facebook, you can use this code:

let appURL = URL(string: "fb://profile/\(Username)")!
