AppCode 3.1 EAP 发布，此版本开始大力支持 Swift。今年夏天，Apple 大会之后，我们宣布支持 Swift 代码基础编辑和代码高亮功能。EAP 重要改进如下：可以在现有的项目中创建基于 Swift 的项目或者新的 Swift 文件；同时还解决了 Swift 代码相关的一些问题；

导航选项能帮助你快速在代码的两个地方切换，对于 Swift 代码，AppCode 现在支持： 

• Go to Class ( Cmd+O ): 

  

• Go to Symbol ( Alt+Cmd+O ): 

  

• Navigate to declaration of symbol at caret ( Cmd+B ). 

Swift 被创建的时候，可以解析并且兼容 Objective-C，所以 Swift API 可以在 Objective-C 和 vice versa 中使用。此次 EAP 构建支持 Objective-C-to-Swift 解决方案。

当前版本对 Swift 的一些限制： 

• AppCode doesn’t provide you with compile warnings in the editor.

• Completion is now working only for the keywords.

• Code formatter for Swift is not ready yet.

• External parameter names, shorthand names and tuple element names are not resolved correctly yet.

• While Swift classes are resolved correctly in Objective-C code, usages of methods are not; we plan to improve this in the nearest updates.

UI 改进

编辑器新特性

其他值得关注的新特性：

• Symbolic breakpoints are now available in AppCode. 

• Find in Path improvements: starting with v3.0, AppCode allows you to search through comments and string literals. In 3.1 EAP, you can also search anywhere except any of these or except both. 

• Git integration was updated with the Reset Current Branch to Here action in Git Log. 

• Rollback action is now available for a code selection via Alt+Cmd+Z or left-gutter menu. It will revert the exact selected block but won’t touch other code containing changes. 

同时还有一些性能提升和 C++ 改进。完整修复列表请看 issue tracker 。请大家注意，系统最低要求已修改：最低支持 OS X 10.9 和 Xcode 6.1。 

此版本现已提供在 our EAP page 。 

Develop with pleasure!
