### Reduce Disk Space

- Note: on your own risk

1. If don’t do the watchOS related work, delete:

```auto
/Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/watchOS.simruntime

```

1. If don’t do the tvOS related work, delete:

```auto
/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/tvOS.simruntime

```

1. If only draw UI by programming, not using `storyboard` etc, delete(better keep it):

```auto
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime

```

1. do sim cleaning:

```auto
xcrun simctl delete unavailable

```

1. delete unused device support files:

```auto
~/Library/Developer/Xcode/iOS DeviceSupport
~/Library/Developer/Xcode/watchOS DeviceSupport

```

1. delete `DerivedData`:

```auto
~/Library/Developer/Xcode/DerivedData

```

1. delete `CoreSimulator` cache:

```auto
~/Library/Developer/CoreSimulator/Caches/dyld

```

### Multiple Versions

If don’t care about the UI of Xcode, you don’t need to install two or more Xcode:

1. copy the `XcodeDefault.xctoolchain` from the newer version to

```auto
/Applications/Xcode.app/Contents/Developer/Toolchains/

```

then rename it, and use it later.  
2. copy the `SDK` to:

```auto
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
/Applications/Xcode.app/Contents/Developer/Platforms/DriverKit.platform/Developer/SDKs

```

and choose the sdk in Xcode’s project config pane.  
3. copy the `DeviceSupport` to:

```auto
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/DeviceSupport
/Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/DeviceSupport

```

**Enjoy!**
