According to the Crash report we experience many crashes on our Widget extention: PlugInKit: -[PKService run]This is happening on multiple iOS versions. We tried to reproduce it wituout any luck and I don't understand from the stack trace why it is happening. Can anyone point me to the right direction?Thread 0 name: Thread 0 Crashed: 0 libsystem_kernel.dylib 0x1ab74900 mach_msg_trap + 20 1 libsystem_kernel.dylib 0x1ab746e0 mach_msg + 44 (mach_msg.c:103) 2

My project supports iOS9 and higher.I'm implementing an ARKit feature but when trying to build to version lower then iOS 11 I'm getting the following message:dyld: Library not loaded: /System/Library/Frameworks/ARKit.framework/ARKit Referenced from: /Users/<*****>/Library/Developer/CoreSimulator/Devices/D6AD6503-A2F7-4EA5-A299-7476BE2B8EB7/data/Containers/Bundle/Application/EF5210C1-DC73-4505-9881-8D8F6B01B723/MyApp.app/MyApp Reason: image not foundIs there a way to add AR support without droing support for lower iOS version?
