AppCode 2016.2 is here, so download and try it right now! And if you've already installed the AppCode 2016.2 RC build, then simply keep it, since it's the same as the released one.

SWIFT

Introduce Variable

One of the most important features from our roadmap, an initial implementation of Introduce Variable refactoring for Swift, is here! Extract Swift expressions from complex ones simply by pressing ⌘⌥V. Replace multiple occurrences of selected expression in one click, and select if you want to specify variable type or make the variable mutable.

Read more about this refactoring in this blog post.

Inspections and intentions

See all errors and warnings immediately in the editor when writing Swift code with SourceKit inspections integrated into AppCode and use the same fix-its as in Xcode for Swift – simply press ⌥Enter on a highlighted region to apply them.

If you happen to mistype something in your comments or code constructs, use the same approach to fix any mistake with new Spelling inspection for Swift.

Read the tutorial to learn more about inspections in AppCode

Live templates

Use Live Templates in Swift to insert frequently-used or custom code constructs into source code quickly and learn more about it in our in-depth Live Templates tutorial.

Parameter placeholders

Have parameter names and value placeholders autofilled simply by invoking completion on a Swift method or function and navigate between them forward and back using Tab/Shift+Tab.

OBJECTIVE-C

Complete Statement

Use Complete Statement (⇧⌘Enter) in Objective-C code to insert parentheses, braces, semicolons and quotes for such code constructs as if, switch or else. Quickly jump to the place where you can start typing the next statement automatically.

Learn how to use this and other types of completion

Documentation

Generate documentation comments for Objective-C/C++ methods in no time, simply by pressing /,/! or ///* and have parameter names inserted into the comment stub automatically.

Use completion inside documentation comment to quickly insert documentation tag or method parameter name.

Benefit from the significantly improved formatting in Quick Documentation (F1) and save your time when updating your documentation – use Rename for method parameters and have them changed automatically in documentation comments.

Debugger

In debugger tool window, the Watches and Variables modes are now merged so you don't need to switch between them. If you still prefer the old style, a new button is available in the watches toolbar to switch between the modes (new mode is on by default).

Besides, performance improvements made for Objective-C debugger should make rendering large data structures, expanding large collections and stepping through the code faster and easier.

MIXED CODE

Easily rename Swift methods and method parameters used in Objective-C and quickly find their usages with ⌥F7.

VERSION CONTROL

The following changes are available for VCS support in AppCode:

• To make navigation through the VCS log easier, we've added tooltips with target commit information for arrows.
• Commit dialog now also shows unversioned files.
• Support for Apply somehow interactive mode for applying patches.
• Git/Hg log shows commit details for several selected commits.

OTHER CHANGES

• LLVM and LLDB predefined coding styles added for Objective-C/C++.
• Font ligatures are officially supported by IntelliJ-based IDEs. If you have a font that supports ligatures installed (e.g. FiraCode, Hasklig, Monoid or PragmataPro), then simply go to Preferences | Editor | Colors & Fonts | Font, choose a corresponding font there and select 'Enable font ligatures'.
• You can now set any custom background image for the editor window via Find Action (⇧⌘A) | Set Background Image.
• IDE notifications are now friendlier – they appear in the right-hand bottom corner and are grouped by subsystem.
• The Inspection results window makes it easier to preview the corresponding piece of code immediately, apply a quick-fix or disable a group of inspections in-place.
