ios12

I am using unarchiveObjectWithData to unarchive data from NSUserDefaults and it is working good, but it was deprecated in iOS 12.0. Xcode suggests to use unarchivedObjectOfClass:fromData:error: , but this method does not work. I have an array of objects of my class to unarchive. I have tried to use unarchivedObjectOfClass:fromData:error: , also unarchivedObjectOfClasses:fromData:error: with all classes (NSArray, NSString, MYCLASS..)

ARKit 2.0 added a new class named AREnvironmentProbeAnchor. Reading it's instructions, it seems that ARKit can automatically collect environment texture (cubemap?). I believe that we can now create some virtual objects reflecting the real environment. But I am still not clear how this work, particularly how the environment texture is generated. Does anyone have simple sample code demonstrating this cool feature? Its pretty simple to implement environmentTexturing in your AR project. Set the environmentTexturing property on your tracking configuration to automatic (ARKit takes the video feed
