Thanks for showing your code and I could not reproduce the issue you described. Whether I include your code into a sample code of CollectionView, memory consumption does not show significant difference. One thing. I see deinit happens in popped ViewController but not with its CollectionView Cell. One possibility, your CollectionView Cell is causing the issue. Can you create a brand-new project, which is minimized just to reproduce the issue, and show full code of it? Steps needed to reproduce the issue would also be welcome.

Please show your code generating UIContextMenuConfiguration. `

I'm a little confused as to what you mean by calling that function. Where would I call that function? And what is the requestItentifier in that function? Seems you do not know how to respond to user notifications. Please show your code instantiating your LocalNotificationManager.

React Native is not a framework of Apple's. Better visit the supporting site or a community site of it.

Seems you are using a third party library. You should better contact to the author of the library to tell it may not be compatible with the iOS SDK of Xcode 12.4.

 I am going to rollback all of the changes and continue develop on Swift 5. Seems to be a reasonable decision. If you have some difficulties using the binary framework with Swift 5, you can utilize the forums, but it might be better for you to contact to the author of the framework.

Please make a better formatting to your code, start with ``` only line and end with ``` only line. You declare the type of your first property id as ObjectIdentifier (which is rarely used), but passing an instance of UUID to it. Try changing the definition of DoseModel as follows: struct DoseModel: Identifiable { var id: UUID //- var date: String var medicine: String var units: Double //- You use `doubleValue` for `value` var value: String } By the way, what is JSON? I guess you are using an old third party framework which once was popular in ancient Swift developers. But currently, it is considered to be a ruins of old era. You should better move to Codable.

When will the loop finish? When arrayOfItems is finished? Or a longer Array finished? Or else you want an infinite loop? In case When arrayOfItems is finished: for i in arrayOfItems.indices { let elt1 = arrayOfItems[i] let elt2 = arrayOfFive[i % arrayOfFive.count] print(elt1) print(elt2) print() } (Assuming arrayOfFive is not empty.)

Xcode needs to be installed on a startup drive of macOS. Better clean up your Mac's startup disk.

Firebase is not a framework of Apple's. You will get better responses sooner if you post such questions in a proper site, such as supporting site or community sites of Firebase.

I guess I have chosen a bad term. Please show your code responding to notifications.

Please show your code currently registering notification and handling notification. Waiting for the code handling notification.

Also, I'm not familiar with how to schedule a new notification when the existing one fires. What function is that? Please show your code currently registering notification and handling notification. You once wrote This works perfectly.

You may register a notification with specifying the start date, no repeating. You can re-register the everyday notification when processing the date specified notification. Or you can register a next notification at each time you received a date specific notification.

Thanks for revealing the fact you found. In fact, I was just changing height while trying (although you clearly described change width and height in your original post). Will try to help better if I have next chance.
