Xcode is 24 percent smaller, skipping intel and metal toolchains
Faster text input
Workspaces load faster
Workspace and Editing
Intuitive editor tabs
Tab start page
Multiple word search, unordered like a search engine
Accessibility, coding by voice, understands swift syntax
#Playground
Embedded like previews, but for any code
Have to import Playgrounds first
Kinda like doing simple debugging with sample data
Very nice visual outputs for various types, such as a map or regex match
Results update immediately when modifying other code
There are plans to open source this, so it can be used outside xcode
Icon composer
All versions of an icon in a single file generated by the app
String catalogs
Type-safe imports for strings with arguments
Auto generated comment for translator describing string’s use
Intelligence
ChatGPT conversations in the sidebar
Ask questions or let it make changes
Smaller menu to make changes to a code selection
Xcode sends project context to chatgpt, which can then query for additional context
Can toggle project context off, also toggle auto-apply for suggested changes
Use the at sign @ to reference project symbols in chats
Code snapshots can be unwound everytime the AI makes changes
Inline code assistant
Generate docs or playground or explain
Try to generate a fix for compile error
Can add multiple models
ChatGPT preconfigured, with limited default requests
Add other network or local models
Debugging and Performance
Step into swift tasks!
Task info displayed in variables view, and thread stack
If the app crashes in debug due to missing usage description entitlement, xcode will just prompt you to enter it
Processor trace is much higher detail than a process sample, since it captures all branches and instructions the CPU makes. (Requires M4 / iPhone 16 hardware support)
New CPU counter and SwiftUI and Power profiler instruments
Better diagnostic trends in Organizer
Surfaces key issues easier, and highlights when they started
Metrics can compare your app to similar apps
Building
Explicit modules for swift by default
Swift build open sourced
Ongoing work to include in SPM
Can add apple’s own enhanced security entitlement
Testing
UI testing automation recording can generate code
Provides multiple possible element identifiers in a drop down menu
Can also copy identifier code from failed tests, in the reports
Thread performance checker can find work that should not be on main thread
