Using the Entry macro to reduce boilerplate when adding custom values to the SwiftUI environment #iOSDev #SwiftUI https://t.co/OLtGWkgwHf

Using if and switch as expressions #SwiftLang #iosdev https://t.co/a2F3ATKFYu

@lukaskubanek I never heard anything, and it was still broken in iPadOS 17. I just retested it and it looks like it’s fixed in the iPadOS 18 beta.

Good to see that NavigationSplitView (iOS 16) has many of the same configuration options as UIViewSplitViewController. https://t.co/didvRccC9M

Turning on strict concurrency checking doesn't protect you from accidentally blocking the main actor. Something I find way too easy to do as I learn how to use Swift Concurrency. #SwiftLang #iOSDev #SwiftUI https://t.co/w99aLVPugd

[Keith Harrison @kharrison]

Still using print statements to debug your App. Maybe it's time you moved to the unified OS logging framework? #iOSDev #Xcode https://t.co/OlF1h5oUtC

Silencing the Core Data CloudKit sync debug messages that fill the Xcode console #iOSDev #CoreData #SwiftData https://t.co/0avmf9bnJk

I never fully understood what was going on using Xcode Intent Definition files to create app shortcuts. The App Intents framework (iOS 16) gets rid of the config files but it's still a lot to learn. #iOSDev https://t.co/5wEWyM3B2F

Let’s get the year started with a couple of #SwiftData bug reports about fetching pending changes https://t.co/XLQGMhJnI3

[Keith Harrison @kharrison]

There are at least three ways to delete data from a SwiftData store. Here’s a quick recap. https://t.co/PgzX0Lvj8I… #iOSDev #SwiftData

Each year I think I’ve done the last update to my Auto Layout book but Apple manages to change just enough to tempt me. The latest edition is updated for Xcode 15 and iOS 17. For 20% off with code BLACKFRIDAY follow this link https://t.co/NVdfFHELsy #iOSDev

[Keith Harrison @kharrison]

In iOS 17, Apple added control over which column shows when a Split View collapses to a single column. #iOSDev #SwiftUI https://t.co/egHhuscZPd

[Keith Harrison @kharrison]

iOS 17 adds support for custom UIKit traits that bridge to the SwiftUI environment #iOSDev #SwiftUI https://t.co/luEZble9hz

[Keith Harrison @kharrison]

Apple deprecated traitCollectionDidChange in iOS 17, replacing it with a method to register for specific trait changes. #iOSDev #UIKit https://t.co/KSCUeWgKQo

Everyone gets the dynamic island but not much else is new with the iPhone 15 screen sizes https://t.co/uUqbish18O #iOSDev

Turning on strict concurrency checking for all targets in a Swift package: https://t.co/MBeswm55Fn #iOSDev #SwiftLang

[Keith Harrison @kharrison]

There's not much (any?) documentation on how you run background SwiftData tasks. Here's what works for me. #SwiftData #iOSDev https://t.co/EI1JrXRMkq

[Keith Harrison @kharrison]

In iOS 17, Apple deprecated the onChange(of:perform) view modifier replacing it with two new variations. #iOSDev #SwiftUI https://t.co/pMMPh7pJ6t

Migrating to Observable https://t.co/TPzYL3hHXR #iOSDev #SwiftUI
