Novice recommendation

? Ranges in Swift explained with code examples

@zoeGuo : The article introduces the different types of Range in Swift: ClosedRange, CountableClosedRange, and the usage and rules of using simple operators instead of declaring Range. And it demonstrates how Range is converted to NSRange and how Range handles special characters in string usage. The article is suitable for Swift novice to quickly understand how to use Range.

? file behavior change in Swift 5.8

@AidenRao : Prior to Swift 5.8, both #file and #filePath returned the full path of the file, which may reveal sensitive personal information. Since Swift 5.8, #file supports only returning the filename and the module it appears in. This feature is disabled by default and can be enabled by adding -enable-upcoming-feature ConciseMagicFile to Other Swift Flags.

? Parallax header effect in SwiftUI using CoordinateSpace

@Barney : This article introduces the scrolling parallax effect using CoordinateSpace in SwiftUI.

  • Creating ParallaxHeader View: Create a ParallaxHeader view, including coordinate space, content and default height parameters.
  • Adding Blur Effect: Add a blur effect to the head view.
  • Offset Calculation: Calculate the head offset based on the relative position of the GeometryProxy and the coordinate space.
  • Height Calculation: Calculates the height modifier for the head view.
  • Usage: Shows how to use parallax headers in SwiftUI views.

? How to Open using Rosetta in Xcode 14.3

@Smallfly : Rosetta is a software translation tool developed by Apple that can translate and run applications based on Intel architecture instructions on the new Apple Silicon processor-based Mac.

After Xcode 14.3, the option to enable Rosetta in the application details was removed and integrated into the simulator selection list to facilitate switching between different architectures.

? Accessing Security Scoped Files

@Damien : The application of iOS App cannot directly access files outside its own container, such as files stored in iCloud, if you read them directly, you will receive a permission error prompt. If you need to access these files, you need to use the API related to the security scope. This article will introduce how to use these APIs in detail, interested students may wish to read it.

? Skip typing your login credentials manually with Xcode breakpoints

@anotheren : The article uses login credentials as an example to introduce how to use Xcode breakpoints to automatically enter debugging content. This method is non-invasive to the code and is a very useful Tips.

the code

swift-power-assert

@笑笑饮食酸: Power Assert is an assertion library created using the macro functionality in Swift. Swift macros are an experimental feature, so a pre-release Swift toolchain is required. When writing tests, we need to use different judgment functions. There are many Assertion APIs. You don’t need to memorize them by rote. You only need to create an expression that returns a Boolean value, and Power Assert will automatically display rich error messages.

Canopy

@JonyFang : Canopy is recommended for the CloudKit tripartite library, which isolates a series of external dependencies related to CloudKit, making the code easier to test.

Book

The Book of Modern C++

@kemchenj : This is a book compiled and published by domestic C++ developers. The content is collected from articles written by excellent authors on the Internet. This book contains ten themes:

  • Basics
  • Modern C++
  • C++23
  • Metaprogramming
  • Concurrency
  • Performance
  • Algorithms
  • Techniques
  • Tricks
  • Miscellaneous

Preface: It is not only broad, but also subtle, combined with the theme, so as to make the content of the book deep and broad. Each chapter is independent and has its own discussion, so this book is aimed at advanced developers. If this is the case, novices can also advance in this way. The small and big things are lost, and they have a detailed understanding.
