Need help with Audio Units in iOS 11. I have two iOS apps: an app that provides a V3 Audio Unit, and a host app for Audio Units. The problem is that when I compile the host application in Xcode 9.0 with iOS 11 SDK and run it on an iPhone with iOS 11, the host application doesn't see the Audio Unit.
I made some research and here's what I got:The problem affects any audio unit app, not only these two specific apps. You can easily see the same problem if you use an AudioUnitV3Example project from the Apple's website (https://developer.apple.com/library/content/samplecode/AudioUnitV3Example/Introduction/Intro.html). This sample project consists of two apps: iOSAUv3Host, and iOSFilterDemoApp that provides an Audio Unit App Extension. You need to install both applications on your iOS device.
When you launch AUv3Host app, it will show you a list of all Audio Units available in the system:
I also downloaded Xcode 8.3.3 with iOS 10 SDK (from https://developer.apple.com/download/more/) and tried all possible configurations of build SDK's and device's iOS version. Here's what I got:
So, it looks like the problem appears only when BOTH conditions is valid: device have iOS 11 installed, and the host app is compiled with the iOS 11 SDK. Audio Unit compilation doesn't affect the problem.
Do you have any ideas how to fix this? And is there a way I could fix this, or it's an iOS 11 SDK bug, and this can be fixed by Apple only?

Problem solved. I also submited the issue as a bug at bugreport.apple.com, and I've just got the answer from the Apple team:
Engineering has requested the following information regarding your bug report: Please add the Inter-App Audio Capability to your application. This is a privacy requirement and was mentioned during the WWDC talk. Since the AUv3Host requires self-signing the entitlement is lost. All AUv3 hosts require the Inter-App Audio entitlement to see v3 audio units. We will look into how to make this even more explicit and will update the sample to avoid these issues.
This works like a charm. iOS 11 device is now able to see all the 16 Audio Units, including the FiltedDemo.
It would be nice if this requirement was more obvious. I hope that Apple will update their documentation and the sample project.

Buried in the deluge of developer announcements that Apple made at their World Wide Developer Conference yesterday was an interesting development for iOS mobile music making: Audio Unit Extensions.
Here’s what Apple has to say about Audio Unit Extensions:
The Audio Unit extension point allows your app to provide musical instruments, audio effects, sound generators, and more for use within apps like GarageBand, Logic, and other Audio Unit host apps. The extension point also brings a full audio plug-in model to iOS and lets you sell Audio Units on the App Store.
It will be months before we can see how this plays out – but it looks like this is an attempt to combine the benefits and flexibility of audio plugins with the sandboxing and distribution benefits of the App Store model.
It also promises to make it easier for developers to create audio effects and synths for both iOS & OS X platforms, and to make it easier for end-users to buy and install them. Mega man x wallpaper backgrounds.
Developers can see the App Extension Programming Guide for additional details.

You can install Audio Units plug-ins from manufacturers other than Apple to process audio in Logic Pro X, GarageBand, and Final Cut Pro. When installed, Audio Units plug-ins appear as individual components in the Library folders on your Mac:
Built-in effects and instruments included with Apple apps like Logic Pro X, GarageBand, MainStage, and Final Cut Pro X don't appear in the Library folders and can't be removed manually.
