Retrospective Timelines was an iOS app that built in 2019 and 2020.
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…
I’ve been spending a lot of time today thinking about the row for the list of event dates. This has been something I’ve been sort of stuck on for the last couple of weeks. This list is a bit tricky because the data on it is not strictly events. The rows represent date records related…
I spent a little time this evening playing with app icon ideas. This is the one I like the most so far. Update: 2019.10.30 I made my first round of revisions of these. I added some gradients and I replaced the white color with a light grey and I think looks pretty nice.
There are some issues with the NavigationView in SwiftUI that prevent the Master Detail version from showing the back button in portrait mode. To get around this I’m using StackNavigationViewStyle. This is OK on most iPads, but on the larger iPad Pro models in landscape it looks ridiculous. This is my attempt to get around…
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’ve spend the last few weeks working on schema and core data. I’m ready to start working on some more advanced user interfaces. Before I begin I wanted to share some images of what the app looks like as of Oct. 14, 2019. Timelines will likely change very little, but I have a lot of…
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…
Naming things is HARD
This morning I made some change to the way that I get events data from Core Data. I outlined my thinking behind this yesterday. Today I put it into practice in the app. There are two types of events in Retrospective Timeline I wanted a way to explode the second type of event into multiple…
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…
