my container App is written by objective-c,then I used Xcode8 beta3 to create a new target of Application Extension which used swift ,when I build my project ,I got the error:

Effective srcDirs: {( <DVTFilePath:0x7fdca8e8fb40:'/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator'>, <DVTFilePath:0x7fdcbdfc31f0:'/Applications/Xcode-beta.app/Contents/Developer/Toolchains/Swift_2.3.xctoolchain/usr/lib/swift/iphonesimulator'> )}

this error happened like in the progress of copying Swift standard libraries into xxx.app.

how can I fix this ,hope some one can help me
