Swift Hashable:错误无法执行命令Killed 9

我有一个大型数据模型,其中的对象需要可以进行比较。为此,我向他们添加了hashValue getter,如下所示:

var hashValue:Int
{
    let h1 = (31 &* id.hashValue)
        &+ caseID.hashValue
        &+ statusID.hashValue
        &+ assignedToID.hashValue
    let h2 = h1 &+ runID.hashValue
        &+ templateID.hashValue
        &+ typeID.hashValue
        &+ priorityID.hashValue
    let h3 = h2 &+ milestoneID.hashValue
        &+ customOS.description.hashValue
        &+ title.hashValue
        &+ estimate.hashValue
        &+ estimateForecast.hashValue
    let h4 = h3 &+ refs.hashValue
        &+ customAutomated.hashValue
        &+ customPreconds.hashValue
    let h5 = h4 &+ customSteps.hashValue
        &+ customExpected.hashValue
    let h6 = h5 &+ customMission.hashValue
        &+ customGoals.hashValue
        &+ customLabel.description.hashValue
    let h7 = h6 &+ customSteps.hashValue
        &+ customStepsSeparated.description.hashValue
    return h7

如果模型对象具有太多属性,我将其分解为如上所述。这很顺利,直到我用相同的处理方法覆盖了几个模型类。现在约。编译时可编辑的10个模型类从1分钟到10分钟,之后编译完全失败并出现以下错误:

Error:unable to execute command: Killed: 9
Error:compile command failed due to signal 9 (use -v to see invocation)
Error:Build failed with 0 errors and 97 warnings in 14m 34s 489ms 

我该怎么做才能防止这种情况发生?我使用的是Swift 4和Xcode 9.2。
