Microphone Class Use Causes Xcode Build Failure

OwlchemyDawson · September 25, 2023, 10:13pm

I have found that having code referencing the Unity Microphone class in a project successfully builds an Xcode project but the Xcode project will fail to compile due to code in AVCapture.mm. Below are the errors that I get from the Xcode project build steps:

Is this a known issue? Will microphone support not be available for Apple Vision Pro?

Click on the error and add && !PLATFORM_VISIONOS

DanMillerU3D · September 26, 2023, 3:20pm

Yeah this is a known issue. Microphone support should be available in the future but not something we’ve enabled through the normal unity path yet.

liquid-shaun · October 25, 2023, 12:10pm

Is there an ETA on microphone access or a potential work around for the time being? Would love to get access to that for a project we’re working on
