If you need to show multiple sheets in SwiftUI it is best to use the framework features to your advantage. Rather than try to abstract the problem into a generic coordinator object, which you then have to unbundle again to customise each circumstance, you can simply create multiple small subview Read more…
I designed a better way to nest property wrappers than other examples I’ve seen in this article and this Stack Overflow question. The sample below is a redesigned version of the code in the question, which I also posted as an answer. Rather than use multiple property wrappers on the Read more…
I’ve seen a lot of code shared online getting the Coordinator wrong so thought I’d share an example of how I believe the Coordinator should be done. makeView returning context.coordinator.textView is taken from Fruta’s PaymentButton.swift but the ideas of the lazy var and textDidChange closure are my own. This means Read more…
There are not many examples of correctly using a Coordinator with UIViewRepresentable so thought I would share one here. You’ll see many examples including some from Apple that return Coordinator(self) which is completely wrong because the UIViewRepresentable is a struct value type which is recreated on every state change so Read more…
It’s hard to find this feature in the documentation so thought I’d share an example here.
Saw this interesting question on Stackoverflow and thought I would answer it. The trick is to use `DynamicProperty as an intermediary as follows:
Update June 2022: windowing APIs have now been added so the code below might not be the best way to implement it. Here is how to open a new window or re-activate an existing one in SwiftUI on macOS. In your ContentView create a button and open a URL for Read more…
Update 30/6/2022: I realised we shouldn’t be initing NSPredicate objects inside body so need a new approach. I was reading Paul Hudson’s article Dynamically filtering @FetchRequest with SwiftUI and thought I would share an improvement for declaring the singers @FetchRequest property that supports a dynamic predicate for filtering: FilteredList.swift ContentView.swift
If we want to use @AppStorage but with a dynamic key passed to the View we can do this: DynamicKeyApp.swift ContentView.swift
Here is one way to implement @AppStorage using a custom UserDefaults suite by way of the defaultAppStorage View modifier and a class extension. GroupDefaultsTestApp.swift ContentView.swift
