在设备上运行时Swift应用程序崩溃 - dyld:未加载库:@ rpath/libswiftCore.dylib

我是ios/xcode世界的新手,并尝试在运行iOS v8.0.2的iphone 5上测试一个简单的Swift应用程序.该应用程序在xcode(版本6.1(6A1052d))中成功构建,但当它尝试在iphone上运行时,它崩溃并出现以下错误:

dyld: Library not loaded: @rpath/libswiftCore.dylib

我已经尝试过大多数建议,这些建议帮助了遇到此错误的其他人,但却没有运气.使用其他团队成员的构建环境构建时,相同的应用程序工作正常.我比较了构建设置,发现它们是相同的.
