Being an iOS developer, it's essential to keep up with the latest tools and features to boost productivity and build outstanding apps. The recent launch of Xcode 15 beta 3 by Apple introduces numerous exciting features and improvements.
In this blog post, we'll delve into some of the significant enhancements introduced in this version and how they can empower developers to streamline their workflows, enhance app performance, and simplify localization efforts.
Expanded OS Support
Xcode 15 beta 3 supports the latest beta versions like iOS 17 beta 3, iPadOS 17 beta 3, visionOS 1 beta, macOS 14 beta 3, tvOS 17 beta 3, and watchOS 10 beta 3.
With the arrival of Xcode 15 beta 3, developers can now enjoy on-device debugging support for iOS 12 and later, tvOS 12 and later, and watchOS 4 and later. To take advantage of these features, it is necessary to have a Mac running macOS Ventura 13.4 or a more recent version.
Profiling Enhancements with Instruments 15
Xcode 15 beta 3 introduces Instruments 15, which includes a new RealityKit Trace template. This template equips developers with powerful profiling instruments for apps and games on visionOS.
The RealityKit Frames instrument provides a visual representation of frame rendering stages, while RealityKit Metrics helps identify rendering bottlenecks. With CoreAnimation statistics, 3D rendering statistics, and more, developers can diagnose and eliminate performance issues to deliver fluid and immersive experiences.
Xcode Cloud Enhancements
Xcode Cloud, Apple's continuous integration and delivery service, receives notable updates in Xcode 15 beta 3.
Developers can now benefit from continuous integration, enabling automatic building and testing of apps as code changes are made. Additionally, continuous delivery capabilities enable seamless deployment of apps to App Store Connect or TestFlight right after successful build and testing. These features simplify the app development process, ensuring faster iteration and feedback cycles.
Performance and Development Workflow Improvements
Xcode 15 beta 3 brings performance enhancements to expedite app development.
Faster build times empower developers to iterate and test their code more rapidly. Improved memory usage ensures that Xcode operates smoothly even with memory-intensive projects, enabling developers to focus on writing high-quality code without unnecessary interruptions.
Swift-C++/Objective-C++ Interoperability
With Xcode 15 beta 3, Swift now supports bidirectional interoperability with C++ and Objective-C++. This means developers can utilize a subset of C++ APIs in Swift and Swift APIs from C++. Enabling C++ interoperability via build settings opens up new possibilities for integrating existing codebases and leveraging the strengths of both languages.

Accessibility Audit Support
To enhance app accessibility, Xcode 15 beta 3 introduces Accessibility Audit support. This automated check helps identify various accessibility issues within your app's views. By utilizing XCUIApplication().performAccessibilityAudit(), developers can proactively address missing labels, text scaling with Dynamic Type, and low contrast, ensuring their apps are accessible to a wider audience.
Streamlined Localization with String Catalogs
Xcode 15 beta 3 introduces String Catalogs (.xcstrings) as a file type for managing app localization. Developers can easily extract localizable strings from their source code, keeping String Catalogs in sync.
The native editor allows for efficient previewing and management of localized strings, simplifying the localization process and ensuring a smooth experience for international users.
Build System Enhancements with Explicit Modules
Xcode 15 beta 3 brings improvements to the build system, including a new mode called explicit modules. This opt-in feature enhances build performance, reliability, and correctness.
Developers can enable explicit modules by setting _EXPERIMENTAL_CLANG_EXPLICIT_MODULES as a user-defined build setting in C and Objective-C projects, which significantly improves the overall development experience.
Conclusion
Xcode 15 beta 3 introduces several groundbreaking features and improvements designed to enhance the iOS development experience. From advanced profiling tools to accelerated build times and streamlined localization, developers have an arsenal of resources at their disposal. Embracing these enhancements will empower developers to create exceptional apps that leverage the latest platform capabilities. As Xcode continues to evolve, developers can look forward to increased productivity and a more streamlined development process.
Happy coding!
