iOS 9 “fbauth2” missing from Info.plist

Question

FBSDKLog: fbauth2 is missing from your Info.plist under LSApplicationQueriesSchemes and is required for iOS 9.0

Any idea what this is? I have added

Answer 1

Please just do not add this to your CFBundleURLSchemes... that will actually HIJACK any app's attempt at Facebook auth, causing a popup to show "X app wants to open " dialog...

You DO NOT want to be doing that.

Answer 2

You can try with below code in swift 5.0

extension Bundle {
   static let externalURLSchemes: [String] = {
      guard let urlTypes = main.infoDictionary?["LSApplicationQueriesSchemes"] 
       as? [String] else {
        return []
      }
      return urlTypes
   }()
}

You can call using Bundle

guard Bundle.externalURLSchemes.contains(URLScheme) else {
    return
}

Write the below code in your info.plist under the **LSApplicationQueriesScheme**

<string>fbapi</string>
        <string>fbapi20130214</string>
        <string>fbapi20130410</string>
        <string>fbapi20130702</string>
        <string>fbapi20131010</string>
        <string>fbapi20131219</string>
        <string>fbapi20140410</string>
        <string>fbapi20140116</string>
        <string>fbapi20150313</string>
        <string>fbapi20150629</string>
        <string>fbauth</string>
        <string>fbauth2</string>
        <string>fb-messenger-api20140430</string>
        <string>fb-messenger-platform-20150128</string>
        <string>fb-messenger-platform-20150218</string>
        <string>fb-messenger-platform-20150305</string>

Answer 4

You can continue to use URL schemes when you build your app for iOS 9 and you want to call URL schemes, you will now need to declare them in your apps Info.plist. There is a new key, LSApplicationQueriesSchemes, and here you will need to add the list of schemes you want to are canOpenURL on.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbauth2</string>
</array>

Answer 5

Just follow the Facebook explanation: Preparing Your Apps for iOS9
Apple mention it in their:Privacy and Your App Keynote 2015

Answer 6

As to v4.6.0 of the FaceBook SDK, add the following key into your plist file:

<key>LSApplicationQueriesSchemes</key>
<array>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
</array>
