Lazy loading in SwiftUI

Those components load all their children up front, so they’re not suitable for implementing a long list of items, as you’d rather have lazy loading.One alternative was using the List component, which implements lazy loading,

Navigation in SwiftUI

Back in July I wrote a post about Navigation in SwiftUI trying to explain the difference between NavigationLink and DynamicNavigationDestinationLink. The latter has been deprecated, so the article is now useless, you can still find it here https://www.gfrigerio.com/navigation-in-swiftui-deprecated/I updated the repository on GitHub to remove the deprecated code and provide a few examples of various

Property Wrappers

Barcode scanner

After a few projects made for fun, and for learning, I decided to publish something useful as a CocoaPod: a barcode and QR code scanner. I worked on a similar feature for an app available in the App Store in Objective-C, and decided to rewrite it in Swift to make it available on GitHub. https://github.com/gualtierofrigerio/GFBarcodeScanner

I’ll update the article as I add functionalities to the project, the

Adding maps to your app

I recently put a sample project on github for using Apple Maps on an iOS application as I wanted to play with Core Location and Maps since I only dealt with Google Maps via Javascript in my existing apps. Here is the link to the project: https://github.com/gualtierofrigerio/GFMapKitWrapper I’ll eventually make it available on CocoaPods so
