在Cocoa程序中访问Swift REPL

我可以将LLDB连接到用Swift编写的程序，并从Xcode中或通过运行以下命令访问REPL：

lldb -n ProcessName
(lldb) repl
  1>

但是，如果我将LLDB附加到一个没有Swift运行时的进程，REPL就不是很有用。例如：

lldb -n Finder
Process 218 stopped
Executable module set to "/System/Library/CoreServices/Finder.app/Contents/MacOS/Finder".
Architecture set to: x86_64-apple-macosx.
(lldb) repl
  1> import Cocoa
error: Couldn't lookup symbols:
  __swift_FORCE_LOAD_$_swiftAppKit
  __swift_FORCE_LOAD_$_swiftCoreGraphics
  __swift_FORCE_LOAD_$_swiftObjectiveC
  __swift_FORCE_LOAD_$_swiftDispatch
  __swift_FORCE_LOAD_$_swiftDarwin
  __swift_FORCE_LOAD_$_swiftFoundation

您知道如何将Swift运行时加载到一个尚未与之链接的进程中吗？这可能是一个非常有用的替代方案，例如注入F-Script。

dlopen（）以进行救援

下载并保存到~/.lldb/inject swift repl

---

然后运行

lldb-nfinder--source.lldb/inject swift repl

注入所有必要的库。请注意，您需要禁用SIP以干扰查找程序。还请注意，有时我必须退出LLDB并重新运行脚本，因为一些dlopen调用失败并返回0。

对于Xcode 10/Swift 4.2，我必须按此顺序加载libs

process load /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/libswiftCore.dylib

process load /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/libswiftQuartzCore.dylib

有人能帮我把这个变成剧本吗？我想把它放到我的lldb init文件中，这样我就可以运行“injectswift”…对于Xcode 6 Beta 4，libswiftAppKit.dylib需要libswiftQuartzCore.dylib。我已经相应地更新了。我发现有用：

find/Applications/Xcode.app/Contents/Developer/-name“libswift*”

，因为我没有在完全相同的路径中找到动态库，所以我更新了10.12和Xcode 8.3.1的答案
