SDKApplicationDelegate Use of unresolved identifier

Question

I have two pods installed for facebook login

pod 'FacebookCore'
pod 'FacebookLogin'

than imported FacebookCore in appdelegate. still it shows use of unresolved identifier error.

I have also implemented tags in info.plist

<array>
<string>fb---------</string>
</array>
<key>FacebookAppID</key>
<string>-----------</string>
<key>FacebookDisplayName</key>
<string>-----------</string>

Still not able to get SDKApplicationDelegate.

func application(_ app: UIApplication, open url: URL,
                 options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
    if SDKApplicationDelegate.shared.application(app, open: url, options: options) {
        return true
    }
    return false
}

Answer 1

Its because SDKApplicationDelegate is changed to ApplicationDelegate

func application(_ app: UIApplication, open url: URL,
                 options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
    if ApplicationDelegate.shared.application(app, open: url, options: options) {
        return true
    }
    return false
}

One more thing to do

class AppDelegate: UIResponder, UIApplicationDelegate

Also import these two pods

import FBSDKCoreKit
import FBSDKLoginKit

Details

• Xcode Version 10.3 (10G8)
• Swift 5
• FacebookCore (0.7.0)

Solution

just replace SDKApplicationDelegate with ApplicationDelegate

Code

import FacebookCore

//....

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

    return true
}

//....

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
    guard let urlScheme = url.scheme else { return false }
    if urlScheme.hasPrefix("fb") {
        return ApplicationDelegate.shared.application(app, open: url, options: options)
    }
    return true
}
