Thank you very much for reporting the issue. For v 4.3.1, we have released static and dynamic SDK's to minimize the symbol duplication and to speed up our SDK startup time. We are working on this failure case and will provide updates as they are available.

Meanwhile, you can use dynamic one to fix your issue. It can be downloaded here:

https://developers.google.com/cast/downloads/GoogleCastSDK-ios-4.3.1_dynamic.zip (link found here:

https://developers.google.com/cast/docs/developers)

Hi, thank you for the response. I will definetly try the SDK from the provided link above, to confirm that the issue is no longer present.
Also it would be awesome if it can be published via CocoaPods, as it removes the need of the detailed project setup descirbed in the tutorial.

Thanks for the update. The dynamic SDK will not be pushed to cocoapods, however the next push to cocoapods should fix the issue. We will keep cocoapods as static and the switch to dynamic will fix the compiler errors, but you would see some runtime warnings about duplicate symbols still. Do let us know if you need any other details.

For v4.3.4 static SDK, issue still exists. Do we have any update?

wi...@gmail.com <wi...@gmail.com> #6Mar 14, 2019 05:04PM

I can confirm that when using the 4.3.5 dynamic framework is working and not failing with duplicate errors issue

For v4.4.2 static SDK, issue still exists.

Still exists for v4.4.4...

Hi, any updates?

nh...@codelink.io <nh...@codelink.io> #11Oct 23, 2019 09:19AM

any updates on the cocoapods, this error still exists for v4.4.5

da...@gmail.com <da...@gmail.com> #12Nov 25, 2019 02:28AM

any update on this? still happening on 4.4.6

Do we have any update on this?

bk...@oreilly.com <bk...@oreilly.com> #14Dec 16, 2019 06:42PM

I'd like to know more about an update on this for v4.4.6 — we've got iOS 13 users experiencing some issues and I'd like to update to the latest static version of the SDK, but this is preventing us from doing so. We can include the dynamic framework in the meantime, but all of the rest of our dependencies are sourced through CocoaPods, so it's a pretty inconvenient workaround.

be...@gmail.com <be...@gmail.com> #15Sep 27, 2020 07:11PM

FWIW, it seems this is no longer an issue in v4.5.0 / iOS 14 / RN 0.63.2
