That's not a thing that exists. platform-client-sdk-ios is a Swift SDK for the Platform API. The WebRTC SDK (genesys-cloud-webrtc-sdk) is a JavaScript library to interface with the browser's WebRTC API to provide a WebRTC softphone. Just want to call that out to make sure you understand what toolset you're working with.
I can't personally help with your xcode/swift issues, but I've made the SDK team aware of this post to have a look.
We have a ticket to fix this issue with the IOS sdk and we will update the ticket with the info you have provided. Please bear in mind though that all SDK fixes are best effort. If you are blocked by an iOS SDK issue you can always fall back on the underlying REST API calls.
Thank you Mr. @tim.smith for your reply and clarification,
so this Swift SDK doesn't support WebRTC, would you please share with me a document or another SDK that helps us develop WebRTC Softphone for Genesys Cloud inside iOS Swift App ?
The WebRTC SDK is JavaScript only. Genesys Cloud does not support non-browser WebRTC endpoints. If you want to place a call from a mobile device, use the devices native API to dial a phone call or create a remote phone for the user to use their mobile phone as a station.
Apologies for the delayed reply. I won't be able to share the ticket as it is not as support ticket but an internal ticket. This post is attached to the ticket however and we will try to post here when the issue gets resolved.
