Following its annual release cadence, Apple formally announced its updated hardware and software during the Apple Event in early September.
iOS and iPadOS have been upgraded to v18, while macOS has been elevated to v15, codenamed Sequoia. Additionally, the dev tool Apple Xcode has been updated to v16.
Regardless of the development framework, apps submitted to the App Store must always target the most recent iOS SDK. Therefore, support for the latest version of Xcode is crucial.
.NET MAUI has announced its support for Apple Xcode 16 in the stable channel of .NET 8 SDK. More details here.
