为什么不'；Xcode 6.3.1方案选择器中显示的t模拟器？

我似乎无法在Xcode 6.3.1中构建模拟器

方案选择器仅列出iOS设备或我的插入式设备，如下所示：

xcodebuild-showsdks

列出了它：

OS X SDKs:
    OS X 10.9                       -sdk macosx10.9
    OS X 10.10                      -sdk macosx10.10

iOS SDKs:
    iOS 8.3                         -sdk iphoneos8.3

iOS Simulator SDKs:
    Simulator - iOS 8.3             -sdk iphonesimulator8.3

它似乎位于应用程序包中的正确位置

我也无法使用xcodebuild为i386和x86_64构建

xcrun simctl list

的输出如下：
