Xcode7.3 beta 新功能
Static Analyser 静态分析增强
• The static analyzer warns when nil is returned from a method or function with a nonnull return
type or is passed to a parameter marked nonnull. (19003620) 返回值是否为空检测
• The static analyzer checks for common misuses of Objective-C generics. (21412472) OC 泛型检测
• The static analyzer checks for missing localizability. This check is off by default and can be
enabled by selecting ‘Yes’ for ‘Missing localizability’ in the 'Static Analyzer - Generic Issues’ build
settings. (23414217) 本地化缺失检查(默认关闭)
Code Completion 代码补全
• Code completion provides better matches with fewer keystrokes and makes it easier to find
what you’re looking for. You can type just the uppercase letters of a method name. Typing
"myDelegate.tveh”, where myDelegate is a UITableViewDelegate, gives tableView(_
tableView: UITableView, estimatedHeightForRowAtIndexPath
indexPath: NSIndexPath) -> CGFloat as the first completion. You’ll also get
completions that better match your intent, so typing “myView.color”, where myView is a UIView,
gives every property containing the “color” substring, like “tintColor” and “backgroundColor”.

Debugging 调试
(主要是view层次级别调试增强,想着取代Reveal?)
• Constraint badges in the View Debugger present values as ratios for better readability when
applicable. (22535224)
• The View Debugger inspector shows referenced views, attributes and values for a selected
constraint. (22266966)
• The View Debugger shows NSWindow size information in the inspector. (18284986)
• The View Debugger has additional options for the assistant editor. The implementation file of
data sources, delegates, and the target of controls can be viewed side by side with the 3D
canvas of your app’s views. (15777861)
• When inspecting a view in the debugger, objects with properties whose values represent
classes such as Target, Delegate, and Data Source will show a navigational arrow in the
inspector. Click this to open the implementation file of that class. As usual in Xcode, holding
Option while clicking will perform the requested navigation in the assistant editor, instead of
replacing the View Debugger canvas. (15884626)
• 3D rotation behavior in the View Debugger is improved. (18313502)
• A contextual menu for items selected in the Views mode of the Debug Navigator and the
Canvas allows you to print the description of an object; focus on a view’s subtree; view
constraints on an object; and hide views obscuring or obscured by the selected view.
(20455506)
• The Views mode of the Debug Navigator allows you to filter the view’s address, label, title, and
superclass. (23095363)
