GVR Audio Engine for iOS crashing

Question

I'm trying to run a program using the Google Resonance Audio SDK for iOS, but every time I try to initialize the GVRAudioEngine, the application crashes and this error appears in XCode:

Thread 1: EXC_BAD_ACCESS (code=1, 
      address=0xffffffffffffffe8)

Does anyone have experience running Google Resonance Audio on iPhone?

Specifically, I'm trying to run the program from this tutorial, Treasure Hunt Demo, the example tutorial provided by Google, but using Xcode 10.0 and iOS 11 or 12, I get the error message above while following the directions.

Answer 1

Use this podfile

target 'TreasureHunt' do
  pod 'GVRKit' , '1.140.0'
  pod 'GVRAudioSDK' , '1.140.0'
end

And run pod update

This crash could be caused when there is a version mismatch between GVRSDK and GVRAudioSDK(source).

Answer 2

Follow the guid step by step and it will work:

• Clone this repo
• In a Terminal window, navigate to the Samples/TreasureHunt folder, and install the CocoaPod dependencies by running this command: pod install
• optionally run pod update to insure you have the latest version
• In Xcode, open the TreasureHunt workspace (Samples/TreasureHunt/TreasureHunt.xcworkspace), and click Run.

Project successfully run with these pods works on Xcode 10:

GTMSessionFetcher (1.2.0)
GVRAudioSDK (1.140.0)
GVRKit (1.140.0)
GVRSDK (1.140.0)
GoogleToolboxForMac (2.1.4)

Troubleshooting:

EXC_BAD_ACCESS means something is not accessible. Maybe it's an object that has been deallocated earlier, or some retain loop. you must investigate it from the stack trace. The following may help:

• open edit scheme ( cmd + < )
• check zombie objects
• run project

It will tell you if a message was sent to a zombie and you can trace it
