TalkApi.shared.profile {(profile, error) in
    if let error = error {
        print(error)

When calling selectFriend(), you can choose the display format and selection type of the Friend picker by specifying the corresponding parameters.

To use the full screen type Friend picker, set viewType to FULL. To use the popup view type, set it to POPUP.

To use the multi picker, set enableMulti to true. To use the single picker, set enableMulti to false. If not set, the multi picker is applied by default.

Other detailed settings such as picker orientation and search function can be modified by specifying OpenPickerFriendRequestParams. For more information on parameters, refer to the reference and Friend picker custom elements.

If the request is successful, the information of the friends that a user selects from the Friend picker is returned through SelectedUsers. If you encounter errors, refer to Error code.

let openPickerFriendRequestParams = OpenPickerFriendRequestParams(
    title: "Single picker", // Name of the picker
    viewAppearance: .auto, // Display type
    orientation: .auto, // Orientation of the picker
    enableSearch: true, // Enables the search function
    enableIndex: true, // Enables the index view
    showFavorite: true // Marks on favorite friends
)

PickerApi.shared.selectFriend(params: openPickerFriendRequestParams, viewType: .full, enableMulti:false){ [weak self] selectedUsers, error in
  if let error = error {
        print(error)
    }
    else {
        print("selectFriend(params:) success.")

        //do something
        _ = selectedUsers
    }
}

let openPickerFriendRequestParams = OpenPickerFriendRequestParams(
    title: "Single picker", // Name of the picker
    viewAppearance: .auto, // Display type
    orientation: .auto, // Orientation of the picker
    enableSearch: true, // Enables the search function
    enableIndex: true, // Enables the index view
    showFavorite: true // Marks on favorite friends
)

PickerApi.shared.selectFriend(params: openPickerFriendRequestParams, viewType: .popup, enableMulti:false){ [weak self] selectedUsers, error in
  if let error = error {
        print(error)
    }
    else {
        print("selectFriend(params:) success.")

        // Implement actions on success
        _ = selectedUsers
    }
}

Retrieves Kakao Talk friend information linked to the Kakao Account of the logged-in user.

Note that Kakao Talk profiles may be different from Kakao Account profiles. Refer to Concepts.

To get the list of Kakao Talk friends of the user currently logged in, call the friends() method in the TalkApi class. You can also pass optional parameters through arguments. If you make a request without any parameters, the default settings are applied.

friends() returns Friends which contains a list of the user's Kakao Talk friends.

If the request fails because the user has not agreed to provide the Friends list, proceed the followings:

• Check if 'Friends List in Kakao Service(Including profile image, nickname, and favorites)' is set to 'Consent during use' in Consent items.
• Request additional consent to the 'Friends List in Kakao Service(Including profile image, nickname, and favorites)' scope.

TalkApi.shared.friends {(friends, error) in
    if let error = error {
        print(error)
    }
    else {
        // Implement service logics
        _ = friends
    }
}

To retrieve the response in the page format, use FriendsContext. FriendsContext includes same paramaeters. When the number of Kakao Talk friends is more than the specified value or default value(100), the response will be returned in the page format. After the first page, use FriendsContext to retrieve the second page.
