What's New in AppCode 2022.3

The new Inline Function refactoring (⌥⌘N) inlines a selected Swift function and substitutes all its usages across the codebase. AppCode will suggest inlinining all invocations and removing the original function or inlining only the selected invocation and keeping the original function.

When creating property from usage or extracting it, AppCode now suggests a choice between var and let property declarations.

The Extract Method refactoring in Swift got several enhancements:

• It takes into account the variable lifetime and scope.
• It no longer misses the mutating modifier.
• It no longer fails in cases where the code you selected to extract starts from a conditional expression.

Code completion in Swift received several improvements to better fit your needs. When completing init and deinit keywords, redundant spaces are removed and the required braces and parentheses are added after the keywords instead.

AppCode 2022.3 also enables the complete statement for initializers and deinitializers.

If you feel unsure about the quick-fix or are just wondering what exactly is going to change, open the Quick Documentation (F1) popup for a selected quick-fix in the ⌥Enter menu. This will activate the intentions preview so you’ll see how the code is going to be updated with the fix applied.

AppCode 2022.3 brings new code analysis checks that warn you about a redundant nullable type and a redundant closure.

When coding in Swift, there can sometimes be pieces of code inside string literals, such as SQL strings, HTML code, or regular expressions. You can now instruct AppCode to treat them as code, which means it can now perform accurate code highlighting based on the language chosen, show language-specific intentions and actions, and even provide the ability to edit a code fragment in the dedicated editor section.

Set the caret on a string, press ⌥Enter, and select the language you want to inject there.

AppCode 2022.3 enhanced UML diagrams for Swift and Objective-C classes:

• You can drag items from files in the Project View to the diagram.
• You can filter nodes on the diagram by scope, like all changed files, opened files, or project source files.

A new solution for synchronizing settings is now available in all IntelliJ-based IDEs, including AppCode. The new Settings Sync plugin is capable of syncing all shareable settings from the platform, bundled plugins, and third-party plugins. The settings are stored in the cloud attached to the user’s JetBrains Account. If you use different IntelliJ-based IDEs associated with the same user account, your settings will be automatically synced.
