Hi All, I am running the latest MacOS 14.0 (23A344), the version of Xcode is 15.0 I have come from the Objective-C days and have decided to give Swift/SwiftUI a try. To become more familiar with the language I am doing an on-line course for MacOS. I am currently playing around with the 'Playground' and in the process of modifying the default "Hello World" coding. Every time I try to modify a project, I get a dialog saying "Unidentified Developer And Differs From Previously Opened Versions" as can be seen by the attached. This is something to do with Security but not sure where as I have never seen this previously. Can anyone please shed some light on what's going on and how to resolve. Pete
