ios - XCode 7 dyld: Symbol not found after setting ENABLE_BITCODE=NO -

i have installed xcode 7 beta 3, , able run code on simulator, not on device. no able build , received warning:

ld: warning: directory not found option '-f/applications/xcode-beta.app/contents/developer/platforms/iphoneos.platform/developer/sdks/iphoneos9.0.sdk/developer/library/frameworks' ld: -bundle , -bitcode_bundle (xcode setting enable_bitcode=yes) cannot used 

so set enable_bitcode=no , device builds, crashes errors:

dyld: symbol not found: __tmdvss5index   referenced from: /private/var/mobile/containers/bundle/application/75c6af90-20d1-4cc7-b206-94c8fad41def/biggercity.app/frameworks/alamofire.framework/alamofire   expected in: /private/var/mobile/containers/bundle/application/75c6af90-20d1-4cc7-b206-94c8fad41def/biggercity.app/frameworks/libswiftcore.dylib  in /private/var/mobile/containers/bundle/application/75c6af90-20d1-4cc7-b206-94c8fad41def/biggercity.app/frameworks/alamofire.framework/alamofire 

my podfile is:

source 'https://github.com/cocoapods/specs.git' platform :ios, '8.0' use_frameworks!  pod 'alamofire', :git => 'https://github.com/alamofire/alamofire.git', :branch => 'swift-2.0' pod 'pubnub', '3.7.10.8’ 

does know causing error? has occurred since installed xcode 7. xcode 6 runs fine.

what needed happen needed clean , delete derived data. after did able run application on device.
