Trying to implement what DTS Engineer posted
https://developer.apple.com/forums/thread/791837?login=true
But This time with REST API & DataModel , This is an Absolute Newbie SWIFTUI question,
Somehow my data model cannot get it working due to my lack of understanding !!, please help
Error "Candidate requires that 'SWIFT_DBG_Workflow_Trans_Datamodel_Data_ListViewModel' conform to 'Identifiable' (requirement specified as 'Data.Element' : 'Identifiable') (SwiftUICore.ForEach)"
