The issue

Hello.

Soon we'll need to use Xcode 15 to build App Store apps and I'm having an issue with AVProMovieCapture. Whenever I open a Unity scene where AVProMovieCapture is used the app crashes with the following message:

dyld[3177]: missing symbol called

This is happening on the following line of AVProMovieCapture.m file:

AVPMC_UnityRegisterRenderingPlugin(UnityRegisterRenderingPluginV5);

This happens if the project is built using the latest Xcode 15 (15.3 at the moment), but it is not happening if the project is built using Xcode 14.3.

Starting April 29, 2024 all apps submitted into App Store must be built with Xcode 15 - https://developer.apple.com/news/upcoming-requirements/?id=04292024a.

Hey @nikolay-fomichev-nl, I'm unable to reproduce this here using a fresh project and the Demo00-ScreenCapture scene with:

• Unity 2022.3.21f1
• AVPro Movie Capture 5.2.4 trial
• Xcode 15.3

Failing to find the symbol would suggest the plugin isn't being copied into the built Xcode project correctly. It should be listed in the "Frameworks, Libraries and Embedded Content" of the Unity-iPhone target as shown here:

[nikolay-fomichev-nl]

Hello @MorrisRH. I checked the project - embed type is set to "Embed & Sign" for AVProMovieCapture and I can find the framework inside of Frameworks folder in the final .app file. I will try to reproduce the issue on a sample project.

Comparing to your setup, though, we have Unity embedded as a library - we do not have standalone Unity application. Could it be somehow related to that?

[MorrisRH]

Yeah, Unity as a library is the issue here. You need to remove AVProMovieCapture.framework from the Unity-iPhone target and add it to your application target's list of frameworks.

[nikolay-fomichev-nl]

Hello. A quick update - the issue was in the build settings of the application target in the project. After fixing them I get AVProMovieCapture running on Xcode 15 as expected without any crashes. Thank you for looking into it.
