How do i fixed this? has anyone been able to get around this?

This error is definitely a little misleading, and hard to figure out whats happening. In short, the device_type property is set in the get_device_info() call, which in turn calls runtime in the agent. It seems like for audio server is fails (or is set to unknown), making the property access to device_type fail when dropping into the warn_about_older_operating_systems() call.

Objections spawning logic is due a major refactor, which would hopefully also fix this by better handling unknown cases.

我也有同樣的問題，最後是發現關閉iPhone的Cydia 的 Shadow Dynamic Libraries hook 就可以使用囉
