1. iOS SDK 2.6, since build 2.6.19, includes two frameworks: Objective C and Swift, and since 2.6.95 Objective C framework is shipped as XCFramework.

2. Due to WebRTC library update, iOS SDK builds since 2.6.86 will work only on arm64 hardware (iPhone 5s and newer).

3. Version 2.5 examples cannot be build with version 2.6 due to changes in video in video capturing to allow custom video capturer implementation. Links in the table above point to compatible source code for each SDK version.

...

Here is described how to build examples using Xcode before 10. Examples building procedure with Xcode 10 and newer slightly differs, and described here. Since iOS SDK build 2.6.114, examples may be built with SPM packages, the procedure is describedhere.

Known issues

1. To play WebRTC stream correctly in iOS application in fullscreen mode it is necessary to follow client device aspect ratio

...

Solution: stream should be published with aspect ratio 16:9 (1280X720 for example)

2. Build 2.6.37 is compatible only with WCS builds since 5.2.935

Symptoms: streaming works in example application, but buttons state and status messages remain unchanged, there can be messages in application logs like

Error converting audioState JSON to FPWCSApi2MediaState
Error converting videoState JSON to FPWCSApi2MediaState

Solution: update WCS build to 5.2.935 or newer

3. It is recommended to use Rosetta when building applications in Xcode for iOS Simulator on Mac with M1 CPU.
