Instant Crash before loading the application with Version 102

[gurhub]

Hello again,

I believe this is not related to this repository but just for reference, I'm opening this issue. I was using version 96 in my application. There was no problem at all. After updating SPM to version 102, I started to receive this issue before loading the application. I try to use it without SPM, just tried to download it from a zip file from URL https://github.com/stasel/WebRTC/releases/download/102.0.0/WebRTC-M102.xcframework.zip. The result was the same.

I don't have time to go deeper, so that's why I go back to version 96.

• Xcode Version 13.4 (13F17a)
• macOS Version 12.4 (21F79)

Here is the full error message on Xcode

Hello,

I encounter the same problem with version 102 (version 96 is fine). I'm using Xcode 13.4 / iOS 15.5.

A quick test:

• create a new project in Xcode and add WebRTC version 102 using Swift Package Manager,
• build and run the app on an iPhone (no need to do an import WebRTC at the top of a source file) The crash occurs.

[stasel]

Hey all Really sorry about that! I have tested the lib before publishing and it worked. Probably was some cached version. I see the crash now.

I'll remove the release and check what happened. Thanks for the heads up

[gurhub]

Hi All,

You're welcome. Stasel, you shouldn't be a sorry man, I've my own open source project too, it happens a lot. We appreciate your quick return.

Also, thank you @anthonynevo for sharing.

Best

[stasel]

I still have some issues compiling and working with M102. However, the good news is that M103 is working just fine and it's due to release next week. So I think it's the best to wait for M103 and release that

[gurhub]

Great news!

[stasel]

Version M103 has been released. I didn't encounter any issues. Can you confirm it's working for you as well?

[sochalewski]

@stasel It works very well for me, thank you for your work! ❤️

[anthonynevo]

Version M103 works perfectly for me as well. Big bonus on the new version: without bitcode, the SPM is much lighter and the loading of the project is blazing fast. Many thanks @stasel for your work !

[gurhub]

I was traveling for a while, and now I've found a time to test. Thank you very much for your effort. The issue is fixed! Also as @anthonynevo said, loading is pretty fast!

Wishing you all a great day!

Best
