ARCall 简介
ARCall 是anyRTC开源的呼叫的示例项目，演示了如何通过 anyRTC云服务，并配合 anyRTC RTC SDK、anyRTC RTM SDK，快速实现呼叫邀请通话的场景。
- 一对一视频呼叫。
- 一对一音频呼叫。
- 多人音视频通话，最大支持50人同时通话。
- 可运用自采集模块，加载第三方美颜库，实现美颜贴图功能。
- 可对接第三方推送实现推送功能。
重构内容
九月份我们对ARCall iOS端项目进行了重构，开发语言由 Objective-C 变为 Swift，通话界面和逻辑处理进行深度优化，希望能给有需要的开发者带来帮助。
下载体验 & 源码下载
ARCall 开源项目支持多个平台，包含Android、iOS、Web、uniapp
开发环境
- 开发工具：Xcode12 真机运行
- 开发语言：Swift
- 实现：音视频通话。
项目结构
ARCall 实现了点对点呼叫、多人呼叫邀请，功能包含视频通话、语音通话、多人通话、sip呼叫、手表呼叫、呼叫中邀请、大小屏切换、悬浮窗、AI降噪、断网重连等等功能。

结束语
针对本次 ARCall-iOS的重构，因时间有限项目中还存在一些bug和待完善的功能点。仅供参考，欢迎大家fork。有不足之处欢迎大家指出issues。
最后再贴一下 Github开源下载地址。
如果觉得不错，希望点个star~
