MergeSwiftModule-在Xcode 6.3中构建Swift应用程序陷入"Merge MyApp.swiftmodule" [英] MergeSwiftModule - Building a Swift app in Xcode 6.3 gets stuck in "Merge MyApp.swiftmodule"

问题描述

在Xcode 6.3中构建应用程序会在步骤Merge MyApp.swiftmodule上停留几分钟(约10分钟):

Building an app in Xcode 6.3 gets stuck for several minutes (approx. 10mins) on a step Merge MyApp.swiftmodule:

MergeSwiftModule normal x86_64 /Users/.../Library/Developer/Xcode/DerivedData/MyApp-crbdsfrhkvpiynaffvhzzsspiels/Build/Intermediates/MyApp.build/Debug-iphonesimulator/MyApp.build/Objects-normal/x86_64/MyApp.swiftmodule

在以前版本的Xcode 6.2和Swift 1.0中这不是问题.

this wasn't an issue in previous version of Xcode 6.2 and Swift 1.0.

推荐答案

为目标启用SWIFT_WHOLE_MODULE_OPTIMIZATION似乎可以解决此问题.
