Unity support for visionOS: What you need to know

The Beta version of Unity’s visionOS support has released an application link , and interested students can apply by themselves.

WWDC23 internal reference has also released a lot of related content, if you are interested, you can check it yourself:

“WWDC23 Internal Reference”

This week we updated 6 more internal reference articles, each of which is of very high quality. Due to space constraints, we recommend three articles at the beginning that may be more interesting to you, and put the rest at the end of the weekly report~

WWDC23 10164 – What’s new in Swift

Winter Melon: This Session involves the new syntax features of Swift and the topic of Swift Macro. These features are of great help in writing more flexible and robust APIs and high-quality code. It also digs into the advantages of using Swift in constrained environments, and discusses Swift’s flexibility in adapting to multiple platform devices and languages.

WWDC23 10167 – First look at Swift macros

Ark (WAMaker): Swift macros are a new feature of Swift 5.9 this year. This article focuses on the introduction of the basic concepts of Swift macros and what needs to be paid attention to in use.

WWDC23 10117 – What’s New in App Store Connect

iHTCboy: This article describes the new features of App Store Connect, including privacy protection, new data types, pre-orders by region, product page optimization, and automation through API. Among them, the TestFlight test, which is only accessible to internal testers, is safe and controllable earlier; pre-orders by region can expand new markets for existing apps; the automation process is realized through API to save time. Finally, it is recommended that developers try new features as soon as possible, optimize product pages, arouse users’ interest, and acquire more users.

Talking about Bazel and Gradle build system from Android perspective

@Crazy : From the perspective of building system comparison, this article compares the differences between Bazel and Gradle from various angles. First of all, it compares the concepts and compares the differences between Bazel and Gradle products, thus leading to the comparison of the concurrency capabilities of the two, and concludes that the implementation of Bazel in terms of concurrency capabilities is simpler and more convenient. Then, from the rapid incremental comparison, the difference in DAG design between the two is drawn. Bazel’s DAG design is better than Gradle’s design in the incremental and configuration stages. Finally, there is a comparison between distributed compilation and dependency management. Bazel’s distributed compilation is its core capability, but for Java/Android compilation, distributed compilation has no significant improvement, while Gradle has an advantage in Java/Android dependency management. At the end, the author compared the two builds of Feishu. The advantage of compiling Gradle for the first time is extremely obvious, and compiling with cache is not far behind Bazel. The author maintains an objective attitude as much as possible throughout the article, making a comparison between Bazel and Gradle, providing you with a choice of ideas, and it is worth reading the article.

How to Use Swift Package Manager to Save Gigabytes of Network Traffic and Disk Space

@Smalfly : This post describes how to use the Swift Package Manager (SPM) to store dependencies in your project’s codebase. This avoids re-downloading and resolving dependencies every time you switch branches. The author created a local package and copied the minimum required files into the project through a script. Doing so reduces file size and optimizes usage of dependencies. In the end, the size of the copied file directory is only 4.7 MB, which is 211 times smaller than the .build directory. The article provides the sample code of the implementation, if you are interested, please refer to the original text.

Bad practice: testing if a String is empty

@JonyFang : This article mainly discusses the problem of detecting whether a string is empty by using string.count > 0 in Swift, and proposes a better alternative.

The problem with using string.count > 0 is that the count property needs to traverse the entire string to count the number of visible characters, so for long strings or cases containing a large number of strings, the execution time will be very long. If you want to execute fast and not be affected by the length of the string, you can use string.isEmpty to detect whether the string is empty. The difference is that string.isEmpty only needs to check if the string contains at least one character.

In the daily development process, try to avoid long strings being judged as empty by count > 0 to avoid unnecessary performance loss.

Convenience Property Wrappers vs Custom Data Access Layer in SwiftUI

@AidenRao : The author takes a to-do application as an example to analyze the advantages and disadvantages of using SwiftUI’s @Query property wrapper and custom data access layer. If you are looking for convenience, you can choose @Query attribute wrapper; if you need more flexibility to replace the data access layer in the future, then a custom data access layer is more appropriate.

Invisible Details of Interaction Design

@水水: Good interaction design will make the product feel like a natural extension of our own behavior. How to achieve an overall balance between form and function, and how to allow users to predict product interaction intentions based on context? This article uses some interaction designs of iOS to introduce how excellent interaction design is a metaphor for user operations. Friends who are interested in interaction or design may take a look, maybe they will gain something~
