GCC Talk iOS app

Video & audio calls and chat for GCC on iOS

GCC Talk is a branded build of the open-source Nextcloud Talk iOS client, maintained by Baitshook. It connects to a Nextcloud server running the Talk (spreed) app and provides end-to-end chat, audio and video calls, screen sharing, polls, and file sharing.

Prerequisites

• Nextcloud server version 14 or higher (that fulfills ATS requirements).
• Nextcloud Talk version 4.0 or higher.
• Xcode 16 or newer.
• CocoaPods

Development setup

git clone --recurse-submodules https://github.com/arshadkhan5/Baitshook-talk-ios.git
cd Baitshook-talk-ios
pod install
open GccTalk.xcworkspace

Always open the .xcworkspace, not the .xcodeproj.

Pull Requests are checked with SwiftLint. Install it locally to catch issues early.

Project layout

Target	Bundle identifier	Purpose
GccTalk	com.gcc.Talk	Main app
ShareExtension	com.gcc.Talk.ShareExtension	Share sheet extension
NotificationServiceExtension	com.gcc.Talk.NotificationServiceExtension	Decrypts push notifications
BroadcastUploadExtension	com.gcc.Talk.BroadcastUploadExtension	Screen sharing (ReplayKit)
GccTalkIntents	com.gcc.Talk.GccTalkIntents	Siri / App Intents
GccTalkTests, GccTalkUITests		Unit, integration and UI tests

All targets share the app group group.com.gcc.Talk. The main app additionally uses group.com.gcc.apps to exchange accounts with a companion Files app.

Branding

The app is preconfigured for the GCC server: forceDomain is on and domain is https://nc.baitshook.com, so users go straight to that server's login page instead of typing a server address. Set forceDomain to NO to get the generic server prompt back.

Everything brand-specific lives in GccTalk/Settings/NCAppBranding.m:

• talkAppName, filesAppName, copyright
• bundleIdentifier, groupIdentifier, appsGroupIdentifier
• pushNotificationServer, privacyURL
• brand colors and logo handling

Logos and icons live in GccTalk/Images.xcassets (AppIcon, gcc_talk, gcc_talk_logo, talk-20).

The app registers the gcctalk:// URL scheme (see GccTalk/Info.plist and AppDelegate.m).

Push notifications

Talk push notifications are relayed through a push proxy. The upstream proxy at push-notifications.nextcloud.com only serves apps signed by Nextcloud GmbH, so GCC Talk runs its own. The proxy lives in push-proxy/ together with deployment instructions; pushNotificationServer in NCAppBranding.m points at https://push.baitshook.com. For troubleshooting on the device side see docs/notifications.md.

WebRTC library

The app uses Nextcloud's builds of the WebRTC library from talk-clients-webrtc.

Running tests locally

Use start-instance-for-tests.sh to spin up a local Nextcloud instance with Talk installed, then run the GccTalk scheme's tests in Xcode. See the ci-*.sh scripts for the individual steps.
