iOS 14 crash after calling play() for each streaming source

[andrew.n]

@Max Hello again, I downloaded your demo project and when I opened it, it looks like this:

This is not looking like a clean installation of the framework in the demo project... looks like the project has already the references of both frameworks: FPWCSApi2 and FPWCSApi2Swift and also two references of WebRTC frameworks in the same folder which is strange...
I copied the frameworks inside the demo project and everything is ok, the project is not crashing at startup...

Also at this step (5) from the docs, it looks like you copy both frameworks to the demo folder, BUT at step 6 I don't see the FPWCSApi2Swift.framework listed... why did this happen?



When I do the same steps for my app is not working...
1) I removed WebRTC from Cocoapods
2) I downloaded both frameworks and I included them in my project and I had to manually include in "Frameworks, Libraries and Embedded Content" the WebRTC.framework that was inside of FPWCSApi2.framework/Frameworks/WebRTC.framework. - If I don't do this manually integration I have build issues because of missing WebRTC.framework - Also, if I want to include the reference of WebRTC.framework from the FPWCSApi2Swift.framework, the initial reference is replaced...
3) I cleaned the DerivedData and the project itself but during the runtime, it is crashing
4) I tried to do a clean build install to a newly created simulator still not working
5) I tried to build the project on a real device and still not working...

On a clean simulator crash:

The screenshot is for iOS SDK 2.6 before Swift framework introduction, we'll fix it.

When I do the same steps for my app is not working...

We raised the ticket WCS-3065 to investigate this issue and let you know results here.

 

[Max]

We investigated the issue and modified the test project you've sent by the following way:
1. Removed GoogleWebRTC from Pods
2. Added WebRTC framework to the project

WebRTC framework should be added from FPWCSApi2Swift.framework

3. Set the following target build options

Enable Bitcode: No
Validate Workspace: Yes

After these steps, the application is build and running successfully without a crash.
You can download modified project here

@Max Small note, also in "Frameworks, Libraries and Embedded Content", FPWCSApi2.framework and WebRTC.framework must be "Embed & Sign".
Also, as I see, GLKIt is no longer required... I changed the project build system from legacy to new build system and everything is working fine now.

Now, considering that the framework is working with the new build system do you consider making the framework available by Swift Package Manager?

Yes, the framework is working with new build system now. There is the ticket WCS-2882 about publishing the framework in Swift package manager, we'll let you know in this topic when if will be ready.

 

[andrew.n]

@Max I did the update as I told you before and we wanted to do some regression testing and during the project archiving we received the following errors:

After I replaced the SDKs I made a build on my real device and I did some testing and everything was fine... I have issues only when I want to send a new build to TestFlight...

 

[Max]

There is the ticket WCS-3049 about it. Please see the temporary workaround in this post

 

[Max]

We fixed build issues (ticket WCS-3049) in iOS SDK build 2.6.22. Please use this workaround to resolve nested bundle issue.

 

[andrew.n]

@Max I downloaded 2.6.22 and I included both frameworks in the same folder... Some issues from yesterday were solved but some weren't ... Take a look in the screenshot above to see the remaining issues we get.

 

[Max]

Take a look in the screenshot above to see the remaining issues we get.

We raised the ticket WCS-3067 to resolve those issues and let you know results here.

 

[Max]

We fixed CFBundleVersion parameter for both Objective C and Swift frameworks in build 2.6.23.
Please also read here how to remove unsupported architectures.

 

[andrew.n]

I included the run script that you mentioned and it looks like the issues were fixed... but other issues appeared

This is know nested bundle issue. You should move WebRTC framework to the same level as iOS SDK framework. Please read here fo details.

 

[andrew.n]

@Max Hello, I saw that there is a new version available (2.6.26) and after I downloaded I saw that the Swift version is changed a little bit... in the first place, it's FPWCSApi2Swift.xcframework (xcframework instead of the framework), and also inside I see that there are folders, for real device and simulator. Can you update the integration guide for this version?

Thanks

 

[Max]

Can you update the integration guide for this version?

No need to update, the integration is the same. The old framework was "fat" including both simulator and real devices architecture support. The XCFramework is "half-fat", it allows XCode to automatically choose the architecture while building for target device. So with XCFramework you don't need to remove unsupported architectures.
