Thinking about SwiftUI

Last week I decided to spend the weekend learning about SwiftUI. The weekend turned into an entire week but I was eventually able to learn everything I set out to learn. This course on Udemy was particularly helpful.

I’m going to take a long weekend to give myself time to reflect on what I have learned so far. One thing I want to think about is if I should use SwiftUI for my app. The app I’m working on is simple enough and SwiftUI can do almost everything I need. There are a few areas where I may have to drop out to UIKit but for the most part I think I can make it work. Importantly, I think I may be able to make a better user experience with SwiftUI than I can with UIKit. So many things in UIKit require more code and complexity and if I stay on that route it may be several months before my app meets the expectations that I have for it.

I guess I have a lot to think about this weekend.

Questions for myself about SwiftUI

This weekend I’m going to spend some time with SwiftUI. I tried to think of the most important questions that I want to answer. I have no idea how much progress I will make but if I come up with answers to these I’ll write about them.

  1. Can I connect a SwiftUI List to a Core Data FetchedResultsController?
    1. How do I set this up?
    2. Load data
    3. Edit data
    4. Delete data
  2. Does SwiftUI support advanced table features?
    1. Readable Size for cells
    2. Reorder controls
    3. Context actions
  3. How can I pass an object from a list view to a form view?
    1. Dependency injection?
  4. Can I make form views that do not save data until the done button is tapped? Pass back to the List view to save the changes. 
  5. Can I easily segue to UIKIT View Controllers? I need access to CollectionViews and Large TextViews, neither of which exist in SwiftUI.

Symbols and icons

I’m working on an icon picker for my app. The idea is to allow users to select a color and icon as a secondary way of identifying their lists. I have 10 colors picked out and the color picker is up and running, and I just wrapped up the first pass at the icon picker. For the time being I’m using SF Symbols. I went through the list of available symbols and found 101 that I think may be useful for my app. I may switch to a third-party icon pack before launch, but once I ship version 1.0 I need to make sure that I’m providing access to a consistent set of icons.
