+// (4 toggles: C1T1 C1T2 C2T1 C2T2 - C1T1&C2T1 use the same truth, C1T2&C2T2 use the same truth )
+// macOS 14 behavior with SwiftUI
+// C1T1's UI will only be updated at most 1 time if we only tap T1.
+// C2T1 will always reflect the latest value in UI. A tap for T2 will make C1T1's UI up to data.
+// Tap on C1T2 or C2T2 will update both toggle at the same time. (Expected)
+//
+// iOS 17 behavior with SwiftUI
+// Tap on C2T1 will only update toggle C2T1 while the UI of C1T1 remains the same.
+// Tap on C1T1 will update both toggle(C1T1 & C2T1) at the same time. (Expected)
+// Tap on C1T2 or C2T2 will update both toggle at the same time. (Expected)
+//
+// iOS 15.5 behavior with SwiftUI
+// Tap on C1T1 or C2T1 will update both toggle at the same time. (Expected)
+// Tap on C1T2 or C2T2 will update both toggle at the same time. (Expected)
+// But one is with transactino and the other is not.
