Error setting property on UIView

[efh365]

I followed the instructions by adding my Shopfiy App. Everything builds properly, but when I run the app I get one error at the beginning, which is

"[error] fault: One or more models in this application are using transformable properties with transformer names that are either unset, or set to NSKeyedUnarchiveFromDataTransformerName. Please switch to using "NSSecureUnarchiveFromData" or a subclass of NSSecureUnarchiveFromDataTransformer instead. At some point, Core Data will default to using "NSSecureUnarchiveFromData" when nil is specified, and transformable properties containing classes that do not support NSSecureCoding will become unreadable."

And then as I click around all the blank pages I continue to see:

"ShopApp[53814:1224949] Failed to set (isAccessibilityView) user defined inspected property on (UIView): [<UIView 0x7fd821ea4570> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key isAccessibilityView."

Any ideas?
