使用 Realm Swift Pod 的应用程序不会 运行（CMD + R，编译 Realm 时崩溃）但它会测试（CMD + U）并且还会存档
APP using Realm Swift Pod doesn't run (CMD + R, crashes compiling Realm) but it does test (CMD + U) and does also archive
我在对我当前的项目进行一些概念验证编译时遇到了一个奇怪的问题。
我们要测试的是我们的项目在 XCode 10.2 下是否可以正常编译（截至今天，Beta 2，我们知道我们也有可用的 Beta 3 和 4）。我们知道这是测试版的东西，我们必须小心使用它，等等...
随便...我们正在处理的奇怪情况是将 Realm 用作 Pod（典型用法，otoh）。版本是 RealmSwift 3.13.1
在XCode 10.1 (Swift 4 world)下我们的整个工程编译通过。
在 XCode 10.2（Betas 2 和 4，还是 Swift 4 World）下，我们的项目无法编译。事实上，它在编译 Realm 时崩溃，并出现严重的 "segmentation fault code: 11" 错误。
我们尝试在 Realm 论坛、Stack Overflow 等网站上四处寻找……但收效甚微。我们不确定 XCode 10.2 对 Realm 的支持，因此我们的问题是：
-XCode 10.2 是否为典型的 "CMD + R" 运行 命令部署编译 Realm？
为了让事情变得更复杂一点，CMD + U（运行 测试套件）和存档命令，编译我们的整个项目 ok，也就是说，编译 REALM 时没有任何问题（在 XCode 10.2 测试版 2 和 4)。所以我们的疑惑很奇怪，我们不确定是不是我们做错了什么，或者 "run" 和 "test/compile" 在 Realm 编译阶段是不同的命令。
关于去哪里的任何提示 check/test？我们开始 运行 没有想法（除了等待 Realm 正式支持 XCode 10.2 beta 2、3 和 4 以防它不受支持）。
问候
编辑：我们一直在努力查明 "Realm Compilation Segementation Fault: Code 11" 的确切原因。据我们所知，我们有这些情况：
1.- 我们代码中使用的 SWIFT 版本与崩溃无关。无论我们使用 SWIFT 4 还是 SWIFT 5，Xcode 10.2 在编译某些 Realm .swift 文件时仍然会崩溃（通过 Podfile 包含）
2.- XCode 10.2 的所有版本都会崩溃（beta2、beta4 和最终正式版本）。 Xcode10.1完全没有问题
3.- 我们试图将我们的 "Data Module" 隔离在一个空项目中（这是我们的领域依赖所在的项目）。隔离此模块时，REALM 可以完美编译。
4.- 当我们将 "Data Module" 集成到我们的 "big project" 中时，然后在编译 Realm 时会出现 SegFault 崩溃。
我们得到的典型 "crash dump" 是（例如）这个（建议将其复制粘贴到您最喜欢的文本编辑器中，前面的线条很丑）：

我发现为什么在我们的 "big" 项目中编译 Realm 会导致 Swift 编译器崩溃。
显然，罪魁祸首是当前模式 运行 部分中的 "Thread Sanitizer" 选项。
看起来，新的 Swift 编译器版本对某些文件有这个问题，正如我们团队在某些 "known issue" 中所指出的那样（我们感到羞耻（？）！）。 =12=]
*Known Issues
The Swift compiler may crash during a build when the Thread Sanitizer is enabled. (48719789)
Workaround: Disable Thread Sanitizer in the Scheme Editor’s Diagnostics tab.
只要禁用 "Thread Sanitizing" 选项就可以 Swift 开心并且不会再崩溃了。
现在让我们希望 Apple 尽快解决这个问题。
你好。
我在对我当前的项目进行一些概念验证编译时遇到了一个奇怪的问题。
我们要测试的是我们的项目在 XCode 10.2 下是否可以正常编译（截至今天，Beta 2，我们知道我们也有可用的 Beta 3 和 4）。我们知道这是测试版的东西，我们必须小心使用它，等等...
随便...我们正在处理的奇怪情况是将 Realm 用作 Pod（典型用法，otoh）。版本是 RealmSwift 3.13.1
在XCode 10.1 (Swift 4 world)下我们的整个工程编译通过。 在 XCode 10.2（Betas 2 和 4，还是 Swift 4 World）下，我们的项目无法编译。事实上，它在编译 Realm 时崩溃，并出现严重的 "segmentation fault code: 11" 错误。
我们尝试在 Realm 论坛、Stack Overflow 等网站上四处寻找……但收效甚微。我们不确定 XCode 10.2 对 Realm 的支持，因此我们的问题是：
-XCode 10.2 是否为典型的 "CMD + R" 运行 命令部署编译 Realm？
为了让事情变得更复杂一点，CMD + U（运行 测试套件）和存档命令，编译我们的整个项目 ok，也就是说，编译 REALM 时没有任何问题（在 XCode 10.2 测试版 2 和 4)。所以我们的疑惑很奇怪，我们不确定是不是我们做错了什么，或者 "run" 和 "test/compile" 在 Realm 编译阶段是不同的命令。
关于去哪里的任何提示 check/test？我们开始 运行 没有想法（除了等待 Realm 正式支持 XCode 10.2 beta 2、3 和 4 以防它不受支持）。
问候
编辑：我们一直在努力查明 "Realm Compilation Segementation Fault: Code 11" 的确切原因。据我们所知，我们有这些情况：
1.- 我们代码中使用的 SWIFT 版本与崩溃无关。无论我们使用 SWIFT 4 还是 SWIFT 5，Xcode 10.2 在编译某些 Realm .swift 文件时仍然会崩溃（通过 Podfile 包含）
2.- XCode 10.2 的所有版本都会崩溃（beta2、beta4 和最终正式版本）。 Xcode10.1完全没有问题

我发现为什么在我们的 "big" 项目中编译 Realm 会导致 Swift 编译器崩溃。 显然，罪魁祸首是当前模式 运行 部分中的 "Thread Sanitizer" 选项。
看起来，新的 Swift 编译器版本对某些文件有这个问题，正如我们团队在某些 "known issue" 中所指出的那样（我们感到羞耻（？）！）。 =12=]
*Known Issues The Swift compiler may crash during a build when the Thread Sanitizer is enabled. (48719789) Workaround: Disable Thread Sanitizer in the Scheme Editor’s Diagnostics tab.
只要禁用 "Thread Sanitizing" 选项就可以 Swift 开心并且不会再崩溃了。
现在让我们希望 Apple 尽快解决这个问题。 你好。
