AppCode 2017.1: Improved Swift Support, New Code Generation Features, and More / JetBrains Blog

Hello, Habr! We recently released AppCode 2017.1, now we are preparing the first update - it's time to talk about all the changes in this version.

Swift

Language support

We implemented support for many changes in Swift 3, among which I would especially like to note:

• SE-0005 - they improved both autocompletion and navigation, and in general the bundle of Objective-C and Swift AppCode began to understand much better:
  
  
  
  
• SE-0062 - learned how to correctly parse expressions with #keyPath(and syntax changes #selectortoo):
  
  
  
  
  
• SE-0091 - Improved code completion for keywords prefix, postfix, infixand implemented correctly navigate between the operator's declaration in the protocol and its implementation. In addition, you can now quickly generate a stub for such operators via Override / Implement :
  
  
  
  
• SE-0033 - supported importing constants from Objective-C using __attribute__((swift_wrapper(struct)))and__attribute__((swift_wrapper(enum)))

A complete list of changes can be found here .

In addition, we implemented support for metatypes , learned how to correctly handle nullability audited regions and nullability attributes in Objective-C, and improved resolution for super.init()and self.init().

Create from usage

In the previous version, we implemented the ability to create variables, functions, methods, and even class properties from their use. And in this we did the same for types (classes, structures, enumerations, protocols) and their initializers:

Override / implement

Override / Implement ( ^O/ ^I) allows you to generate definitions for several methods of a class or protocol at once. In AppCode 2017.1, we made the Override / Implement dialog for Swift more convenient, and the code generation more correct:

• Elements in the dialog are now displayed hierarchically:
  
  
  
  
• Initializers always display type ( convenience/ required)
• Class method overloads are correctly generated, and we no longer offer to overload static methods
• Optional methods are offered only when calling Override (^ O)

Auto completion

Now AppCode can filter the autocomplete list for methods and functions not only by their names but by the names of their parameters:



In addition, we have added keywords dynamic, lazy, postfix, prefixand indirectin the autocomplete list where necessary.

Structure view

We were asked for a long time to add to the Structure view ( ⌘7) and popup window File Structure ( ⌥F12) the display of view comments //MARK, //TODOand //FIXMEfor Swift, and here we are:



If you need a list only //TODOand //FIXMEyou can, as before, use TODO view ( ⌘6):

C ++

By tradition, the C ++ support enhancements implemented by the CLion team are also available in AppCode. You can read about them in this post in the C ++ 14 and C ++ 17 section .

IDE

Build messages

In the assembly message window ( ⌘0), you can now filter messages by type:

Xcode-like breakpoints

By default, clicking on a breakpoint in IntelliJ products removes it, which can sometimes interfere (for example, if breakpoint is triggered if a certain condition is specified in its settings). Now you can avoid this situation by selecting Drag to the editor area in the Preferences | Build, Execution, Deployment | Debugger | Remove breakpoint:

Emoji Support

Like all JetBrains products, AppCode now correctly displays emojis in the code editor and various IDE windows:

Find in path

The Find in Path full-text search window has changed - the interface has become more concise, the need to switch between several tabs in the window has disappeared:
