Xcode 8 syntax highlighting doesn't work
提问by Andrey Banshchikov
The code above has correct syntax highlightingin Xcode 7. It is mix of Obj-C + Swift:
上面的代码在Xcode 7 中有正确的语法高亮显示。它是 Obj-C + Swift 的混合体：
I've updated project to support Xcode 8and only few things was changed:
我已经更新了项目以支持Xcode 8，只有很少的事情发生了变化：
In Build Settings Swift 2.3 support
And have fixed few errors related to implicitly unwrapped properties in UIKit
在构建设置中 Swift 2.3 支持
并修复了一些与 UIKit 中隐式展开属性相关的错误
After all the project is compiled finefor Xcode 8.
毕竟项目为Xcode 8编译得很好。
But Obj-C code integrated in Swift doesn't have any syntax highlightingand vice versa:
但是集成在 Swift 中的 Obj-C 代码没有任何语法高亮，反之亦然：
And there is << error type >>problem with autocomplete:
并且自动完成存在<<错误类型>>问题：
Derived data deleting doesn't help, Xcode restart either :) CocoaPods version 0.38.2, iOS 7
删除派生数据无济于事，Xcode 重新启动 :) CocoaPods 0.38.2 版，iOS 7

Fixed. Problem was related to the presence of target in project which is not compiled. So if you have targets e.g. A, B, C and C is not compiled this cause problems with syntax highlighting.
固定的。问题与未编译的项目中存在目标有关。因此，如果您有目标，例如 A、B、C 和 C 未编译，则会导致语法突出显示问题。

这个答案在我的一个项目中帮助了我https://forums.developer.apple.com/thread/46223：
I got help from an apple engineer at WWDC on this issue and resolved it. The problem stemmed from cocoapods... Apparently cocoapods was copying .h files into the build directory and SourceKit was getting confused. I'm not entirely sure why the .h files were being copied - they aren't needed there. So the fix was to add a post-build script in your build phases section that removes the headers after a build.
It would look something like this:
我从 WWDC 的一位苹果工程师那里得到了这个问题的帮助并解决了它。问题源于 cocoapods...显然 cocoapods 正在将 .h 文件复制到构建目录中，而 SourceKit 感到困惑。我不完全确定为什么要复制 .h 文件-那里不需要它们。所以修复是在你的构建阶段部分添加一个构建后脚本，在构建后删除标题。
它看起来像这样：
function removeHeaders() {
find $BUILD_ROOT/Debug-iphonesimulator/ -name '*.h' -exec rm -f {} \;
}
removeHeaders

I have found that when syntax highlighting falls over, switching tabs in Xcode fixes the issue ˉ_(ツ)_/ˉ sometimes I find I need to switch to at least 4 different tabs before it comes on again.
我发现当语法突出显示失败时，在 Xcode 中切换标签可以解决问题ˉ_(ツ)_/ˉ 有时我发现我需要切换到至少 4 个不同的标签才能再次出现。
Otherwise a quit and reopen
否则退出并重新打开

It happened also to me with Xcode 8 GM but also lots of time when I used Xcode 7: sometimes the auto-complete feature and the syntax highlighting die without notice.
它也发生在我使用 Xcode 8 GM 时，但在我使用 Xcode 7 时也发生了很多次：有时自动完成功能和语法突出显示会在没有通知的情况下消失。
The only solution that it works for me is restart Xcodebut a few times I needed to complete reboot my Mac; I still don't know exactly what causes this annoying problem.
它对我有用的唯一解决方案是重新启动 Xcode，但有几次我需要完成重新启动我的 Mac；我仍然不知道究竟是什么导致了这个烦人的问题。

Commenting and then uncommenting the affected lines worked for me.
评论然后取消评论受影响的行对我有用。

In my case:
就我而言：
In Finder I navigated to user->Library->Developer->Xcode->DerivedData. Close your Xcode Project then Clear DerivedData. It's work for me.
在 Finder 中，我导航到user->Library->Developer->Xcode->DerivedData。关闭您的 Xcode 项目，然后清除 DerivedData。这对我有用。
Happy Coding...:)

As others have stated above - if I create a new tab ..or 4 then close the tab that usually does it. Sometimes commenting out a line then immediately uncommenting does the trick as well. I got tired of using several keys to accompolish this and made a simple AppleScript to do it for me.
正如上面其他人所说 - 如果我创建一个新选项卡 .. 或 4 然后关闭通常执行此操作的选项卡。有时注释掉一行然后立即取消注释也能解决问题。我厌倦了使用多个键来完成此操作，并制作了一个简单的 AppleScript 来为我完成此操作。
Create a Automator 'service' and add this script to it. In System Preferences under Keyboard -> Shortcuts -> Services find your new service and assign it to an empty function key (I used F1) and now you have a 1 key fix!
创建一个 Automator“服务”并将此脚本添加到其中。在“键盘”->“快捷方式”->“服务”下的“系统偏好设置”中，找到您的新服务并将其分配给一个空的功能键（我使用 F1），现在您有了 1 键修复！
