Comprehensive User Guide for Video Calling SDK & API for iOS

What is an SDK?

Software Development Kit is abbreviated as SDK which is basically a collection of software development tools for a particular platform.

This generally includes the development of blocks, debuggers, and a framework or a group of code libraries that is specific to an OS (Operating System).

It simplifies development by providing pre-built components and functionalities that save developers time and effort.

These SDKs are used to streamline the integration of complicated features like video calling that improves app capabilities without any need to develop everything from scratch.

What is an API?

API stands for Application Programming Interface and is considered a collection of rules and protocols that enable diverse software applications in order to communicate with each other.

It defines the methods and data structures required for this interaction and allows developers to access specific features or data of an application, service, or platform without understanding its internal workings.

Generally, APIs are leveraged to integrate diverse software features, simplify development processes, and improve functionality by utilizing existing services, therefore it saves developers time and ensures consistency in software interactions.

What Are the System Requirements for Using the SDK and API?

The system requirements for using an SDK and API for video calling on iOS typically include operating system, device type, development environment, programming languages, hardware, backend services, network connectivity, and permissions. Let’s explore these in a detailed way:

1. Operating System

  • iOS Version: Requires a compatible OS version, such as iOS 12.0 or later, to ensure support for the latest features and APIs provided by the SDK and API.

2. Device Type

  • iPhone/iPad: iPhone or iPad app development ensures the device meets the minimum hardware specifications, such as having sufficient processing power and memory.

3. Development Environment

  • Xcode: Requires Xcode, preferably the latest version, to build, test, and debug the app effectively, along with any necessary SDKs and tools provided by the API.

4. Programming Languages

  • Swift or Objective-C: Swift and Objective-C are the primary languages supported by the SDK for development.

5. Hardware

  • The device should have sufficient processing power and memory, typically an iPhone 6s or newer, to handle video calling operations efficiently without performance issues.

6. Backend Services

  • Server Compatibility: If using a backend service, ensure it meets the SDK’s server-side requirements for proper functionality.

7. Network Connectivity

  • A stable internet connection, preferably Wi-Fi or 4G/5G, is essential for smooth video calling and data transmission, minimizing interruptions and maintaining call quality.

8. Permissions

  • The app must request and obtain necessary permissions for accessing the camera, microphone, and network, ensuring compliance with user privacy and security standards.

What are the Best Practices for Optimizing Video Call Performance?

Some of the best practices for optimizing video call performance in iOS apps include adaptive bitrate streaming, background optimization, effective codec usage, audio processing, connection resilience, and device-specific optimizations. Below is a detailed explanation of these best practices.

1. Adaptive bitrate streaming

  • Implement dynamic adjustment of video quality based on network conditions, ensuring smooth calls even when bandwidth fluctuates, automatically lowering resolution or frame rate when necessary to maintain a connection.

2. Background optimization

Properly handle video calls when the app is in the background by using CallKit for VoIP notifications and optimize CPU usage to prevent iOS from terminating the app during long calls.

3. Effective codec usage

Utilize modern and effective codecs like H.264 or VP8 for video compression, reducing bandwidth requirements while maintaining quality because it is crucial for smooth performance on mobile networks.

4. Audio processing

Implement echo cancellation, noise suppression, and automatic gain control, enhancing audio quality, reducing distractions, and improving the overall call experience, especially in challenging acoustic environments.

5. Connection resilience

Implement robust error handling and reconnection logic that helps maintain calls during brief network interruptions or when switching between Wi-Fi and cellular data, providing a more stable user experience.

6. Device-specific optimizations

Tailor video resolution and frame rate to each device's capabilities, ensuring optimal performance across various iOS devices without overloading older or less powerful models.

What Permissions Are Required for the Video Calling App to use the SDK?

Video calling SDK for iOS requires several key permissions to function properly, ensuring access to essential device features and protecting user privacy. Here's an overview of the necessary permissions:

1. Camera Access

Camera access is highly essential for video transmission. The app must request permission to use the device's camera. Without this, users can't send video during calls. It is requested via the NSCameraUsageDescription key in Info.plist.

2. Microphone Access

Microphone access is crucial for audio transmission. The app needs permission to access the device's microphone for voice communication. This is requested using the NSMicrophoneUsageDescription key in the app's Info.plist file.

3. Push Notifications

Push notifications are important for alerting users about incoming calls when the app isn't active. This permission is requested during app runtime and allows the app to receive and display notifications.

4. Background Mode

Background mode enables the app to continue audio sessions when in the background. This is configured in the app's capabilities and requires the "Audio, AirPlay, and Picture in Picture" background mode.

5. Local Network Access

Local network access is necessary for peer-to-peer connections on the same network. It's requested via the NSLocalNetworkUsageDescription key in Info.plist, allowing the app to discover and connect to nearby devices.

6. Cellular Data Usage

While not a direct permission, users should be informed about potential cellular data usage. This is typically handled through clear user communications rather than a system permission prompt.

7. Photo Library Access

Photo library access is optional but common for features like sharing images during calls. It's requested using the NSPhotoLibraryUsageDescription key in Info.plist, allowing users to access and share photos from their devices.
