I faced a similar problem to the original issue. I noticed, if you have any array of objects(class) : [ObjectA] as an @Published variable in a class: ClassA if you update any property of the objectA in the array [ObjectA], then the subscribers of @Published [ObjectA] will NOT trigger in ClassA import Foundation import Combine class Object {   var value: Int = 6   init(value: Int) {     self.value = value   } } class MyClass {   @Published var objects: [Object] = []   var value: String = "Hello"   var subscriptions = Set<AnyCancellable>()   init(index: Int, value: String) {     self.objects = [Object(value: index)]     self.value = value     $objects       .sink {         print($0.first?.value)       }       .store(in: &subscriptions)   } } func changeMemberProperty(_ obj: MyClass) {   if var first = obj.objects.first {     print("Will change member property")     first.value = Int.random(in: 100...400)   }   obj.value += "World" } var obj = MyClass(index: 1, value: "Hi") changeMemberProperty(obj) changeMemberProperty(obj) func changeMember(_ obj: MyClass) {   print("Will change member")   obj.objects = [Object(value: Int.random(in: 100...400))] } changeMember(obj) changeMember(obj) Output: Optional(1) /* Because of Print-command during initial setup */ Will change member property /* Didn't trigger Print-command */ Will change member property /* Didn't trigger Print-command */ Will change member Optional(292) /* Due to triggered change: Print-command */ Will change member Optional(259) /* Due to triggered change: Print-command */
