无法使用Xcode 8.0和Swift 3构建子项目

Question

我正在运行Xcode 8.0构建版本8S174q和Apple版本3.0 (Switlang-800.0.34.6 clang-800.0.33)。

Pauls-Mac-mini:~ paul$ xcrun xcodebuild -version
Xcode 8.0
Build version 8S174q
Pauls-Mac-mini:~ paul$ xcrun swift -version
Apple Swift version 3.0 (swiftlang-800.0.34.6 clang-800.0.33)
Target: x86_64-apple-macosx10.9
Pauls-Mac-mini:~ paul$ xcrun --find swift
/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift

在https://github.com/stephencelis/SQLite.swift中，我安装了0.11.0版本(注意它是用Swift 3编写的)。我已经尝试了网页上的三种安装方法，经过一天的忙碌之后，sqlite.swift仍然无法编译。通过Xcode Report Navigator (CMD-8)，我看到了数百个编译错误，其中几个我已经粘贴在下面。

/Users/paul/Documents/MySandbox/TestThreeSqlite/SQLite.swift/SQLite/Core/Connection.swift:69:9: error: expected declaration
        fileprivate init(rawValue:Int32) {
        ^
/Users/paul/Documents/MySandbox/TestThreeSqlite/SQLite.swift/SQLite/Core/Connection.swift:58:17: note: in declaration of 'Operation'
    public enum Operation {
                ^
/Users/paul/Documents/MySandbox/TestThreeSqlite/SQLite.swift/SQLite/Core/Connection.swift:69:20: error: consecutive declarations on a line must be separated by ';'
        fileprivate init(rawValue:Int32) {
                   ^

我最初怀疑没有使用Quick3.0编译器，但是从下面的compile命令来看，情况似乎并非如此。

我尝试过3种安装SQLite.swift的方法--使用Carthage、cocoapods和将SQLite.swift安装为Xcode子项目。我不能构建SQlite.swift。

请帮帮我！我对iOS开发、Xcode和工具都很陌生，所以我对此感到困惑。下面我添加了一些更详细的信息，比如生成错误的编译命令。您能提出一个可能的解决方案，甚至是一些我可以尝试让这个子项目来构建的解决方案吗？

造成此问题的原因是使用了一个不支持https://github.com/stephencelis/SQLite.swift 0.11.0版本中的新的快速语言特性(例如，fileprivate访问级别修饰符)的swift版本。很难将Xcode beta构建与快速版本(本例中为迅捷-800.0.34.6 clang-800.0.33 )与快速语言发布说明(Language/RevisionHistory.html)相关联。

我升级到Xcode 8.1，它使用Swift 3.0.1，现在没有任何构建问题。现在Xcode已经不再是beta版了，我希望xcode版本、快速语言代码和快速发布说明之间的交叉引用会更容易。
