无法使用 Xcode 8.0 和 Swift 3 构建子项目
Cannot build a subproject using Xcode 8.0 and Swift 3
我是 运行 Xcode 8.0 构建版本 8S174q 和 Apple Swift 版本 3.0 (swiftlang-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
从https://github.com/stephencelis/SQLite.swift我安装了0.11.0版本（注意它写在Swift 3）。我在该网页上尝试了三种安装方法，经过一天的折腾仍然无法让 sqlite.swift 编译。通过 Xcode 报告导航器 (CMD-8)，我看到了数百个编译错误，其中一些我已粘贴在下面。
/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 swift 3.0 编译器没有被使用，但从查看编译命令（如下）看来情况并非如此。
我尝试了 3 种安装 SQLite.swift 的方法 - 使用 Carthage、cocoapods 并将 SQLite.swift 安装为 Xcode 子项目。我无法构建 SQlite.swift.
请帮忙！我是 iOS 开发、Xcode 和工具的新手，所以被这个难住了。下面我添加了一些更详细的信息，例如生成错误的编译命令。你能建议一个可能的解决方案，或者我可以尝试构建这个子项目的东西吗？

问题是由于使用的 swift 版本不支持 https://github.com/stephencelis/SQLite.swift 0.11.0 版中的某些新 swift 语言功能（例如 fileprivate访问级别修饰符）。很难将 Xcode 测试版与 swift 相关联
版本（在本例中为 swiftlang-800.0.34.6 clang-800.0.33）到 swift 语言发行说明 (https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/RevisionHistory.html).
我升级到 Xcode 8.1，它使用 Swift 3.0.1，现在没有发现构建问题。现在 Xcode 不再是测试版，我希望 xcode 版本、swift 语言代码和 swift 发行说明之间的交叉引用会更容易。
我是 运行 Xcode 8.0 构建版本 8S174q 和 Apple Swift 版本 3.0 (swiftlang-800.0.34.6 clang-800.0.33)。
