I compare my attempt at a Core Data caching challenge—storing fetched user data so the app can still display it after network failures—against Paul’s model solution. Differences covered include adding a merge policy for handling constraint conflicts, keeping ids as UUIDs, and placing MainActor.run inside the network fetch rather than after it...
I compare my solutions with Paul’s video for a SwiftUI challenge built around FilteredList, covering passing a predicate as a string, converting to enums, and adding sort descriptors. The enum task matched Paul’s exactly, while sort descriptors caused some struggle with NSSortDescriptors until I spotted the hint to use SortDescriptor instead...
My solutions to the three wrap-up challenges from Project 12 of the Hacking with Swift SwiftUI series, which involve a FilteredList subview whose @FetchRequest is built dynamically in its initializer. The tasks add a predicate format parameter, replace the hard-coded predicate string with an enum using raw values, and support an array of SortDescriptor objects...
A comparison of my solutions to Paul Hudson’s for a SwiftUI challenge covering address validation, alerts for failed POST requests, and wrapping a struct in an observable class. I find Paul’s String extension approach to whitespace checking neater than my brute-force version, and I highlight Paul’s use of @dynamicMemberLookup with key paths to shorten chained property access like order.data.street down to order.street...
My solutions to the day 52 challenges for the Hacking with Swift Cupcake Corner app: trimming whitespace before validating the order address, showing an alert when the order submission to the API fails instead of just printing, and converting the Order class to a struct inside an ObservableObject wrapper to eliminate the manual Codable code. I present each change with Swift code snippets and links to the corresponding GitHub commits...
