This is something I keep forgetting how to do so I’m posting this as a reference for future me and anyone else that finds it helpful. These instructions assume you have created a new Xcode project with these options. This will create some boiler plate Core Data code in the AppDelegate and SceneDelegate. In the…
Up until now I’ve been using separate views for Event Detail (view only) and Event Edit. I decided to try to combine these into one view and work them into the main navigation stack. This way event data entry can be done without opening a modal. Adding a new event will still be done in…
I based most of my core data code for Retrospective Timelines on an example project that you can check out here. The developer sent me the link to this in a comment on stack overflow a couple of months ago. Throughout the project I’ve made small changes to this to better suite my needs. Today…
Yesterday I mentioned an issue I can across when sorting date records. Some of my date records could validly have a nil value in the date field (these are the “end” records for ongoing events). The problem was that Core Data was sorting these nil records to the wrong part of the list. When sorting…
I wrote about a sorting issue in Retrospective Timeline a while back. You can read the full post here. At the time I decided to go with Solution A, which involved wrapping my core data objects in a container using map and filter calls. That approach worked at first, but there were some issues when…
This is a short follow up article regarding the problems I described in this post. I spent some time mocking this up in a Swift Playground on my iPad. First I added a new container object called EventContainer. This is an object that I can map my events to, while keeping a reference to the…
Objective: I need a way to sort events in a list view that makes them easy to find. Constrains: Options: I’d like to proceed with option three from the list above. Using this approach will place an event in the list twice if it has a start and end date. I can format the rows…
