打开Storyboard时出现Xcode崩溃

Question

为了支持从iOS 7到iOS 9的iOS,我安装了Xcode 6和7.然后我在Xcode 7上为iPhone创建了一个项目.我在Xcode 6上打开它以在iPhone模拟器7上进行测试.

但是当我点击Storyboard文件时,Xcode 6崩溃了.

我该如何解决？或者还有另一种方式来支持iOS版本？

Answer 1

原因是Xcode 6和7之间存在冲突.Apple在Xcode 7的发行说明中对此进行了揭示.

我按照步骤操作,错误得到解决.

"从Xcode的下载首选项安装iOS 9.0 Simulator Runtime会导致Xcode 6中的Interface Builder安装在同一台机器上以停止运行.要么避免安装iOS 9.0 Simulator Runtime,要么移动/ Library/Developer/CoreSimulator/Profiles/Runtimes/iOS \切换到Xcode 6时将9.0.simruntime更改为备份位置,然后将其移回Xcode 7(23230951)"
