We promised to dedicate this release to performance improvements, and here they are:

  • Highlighting, code completion, and navigation in pure Swift and mixed projects should work a lot faster compared to AppCode 2019.2.
  • We’ve boosted caching so that “Processing Swift Modules” should be much faster compared to previous AppCode versions.

Some major improvements started during this release are still in progress and scheduled for the next release. We’re staying on course and our main focus areas for 2020.1 are, again, performance boosts and language support.

Language Support

AppCode 2019.3 brings support for the following Swift 5.1 features:

New Intentions

A whole heap of new Swift intentions are here to boost your productivity:

  • Split / join variable declaration and assignment:Split / join variable declaration and assignment

Code Generation

We’ve added two new options to help you generate Swift code: Prefer Void over () and Prefer explicit return. Find them in Editor | Code Style | Swift | Code Generation | General.

Code Formatting

New useful code formatting options are here:

  • Keep simple property blocks with willSet/didSet on one line (Preferences | Editor | Code Style | Swift | Wrapping and Braces | Keep when reformatting | Methods and functions in one line).
  • Keep empty type declarations on one line (Preferences | Editor | Code Style | Swift | Wrapping and Braces | Keep when reformatting | Empty type declarations in one line).

Alternative Swift Toolchains

Are you working with the Swift Tensorflow toolchain or another custom Swift toolchain? Now we correctly load all the code constructs for custom Swift toolchains and use them for building, running, debugging, and testing.

Build Messages

We’ve fixed dozens of UX issues by reworking the Messages tree, which now shows the same information as Xcode does:

Build messages

The build progress bar now shows accurately how long it’s going to take to compile your application:

Build messages progress

The message filter is simplified and now offers the same options as Xcode does: All Issues, Errors and Warnings, and Errors Only.

Mac Catalyst Support

Code assistance, build, run, and debugging now work for Mac Catalyst projects.

That’s it! Explore all the new features in detail on our website and start your free 30-day evaluation to try them in action!
