Thanks, var toExcludeOrCopy : AnyObject?
Could help me on some cases... But if I try this: var props = [AnyObject]() props += contact.phoneNumbers ( "contact" is as CNContact, so "contact.phoneNumbers" is [CNLabeledValue<CNPhoneNumber>] ) I get this error: /Users/laullon/xcode/bipo/BiPo/MergePreview.swift:82:21: Cannot convert value of type '[AnyObject]' to expected argument type 'inout _' With: props.append(contentsOf: contact.phoneNumbers) I get this error: /Users/laullon/xcode/bipo/BiPo/MergePreview.swift:83:33: Extraneous argument label 'contentsOf:' in call Any Idea?
