在基本块的中间发现终止符
Terminator found in the middle of a basic block
一切顺利，直到我的项目 compile.I 在我的两个文件中看到那些东西。
Terminator found in the middle of a basic block!
label %50
LLVM ERROR: Broken function found, compilation aborted!
Terminator found in the middle of a basic block!
label %71
LLVM ERROR: Broken function found, compilation aborted!
以及编译器给出的错误
Command /Applications/Xcode-beta 2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1
我尝试解决它，但没有成功。
编译旧版本的文件。
问题出在文件上，但是终结符是什么？
问题出在哪里？

这是 Swift 编译器中的错误，您需要向 Apple 提交雷达报告此错误。否则你无能为力。
我遇到这个错误是因为我用一个包含数组有效负载的案例切换了一个枚举（别问我为什么，我不知道）。
我认为枚举是 tableView:cellForRowAtIndexPath 中的 搜索状态 ：SearchViewController 的方法和 prepareForSegue：LandscapeViewController 的方法（.Result 案例包含一个列表） .
在我的例子中，将负载更改为 Set 而不是 Array 是可行的。 （作为解决方法，直到它被修复）
