我在 Xcode 中收到此消息，知道如何修复它吗？

来自https://forums.developer.apple.com/thread/3380 :
Xcode failed to download the symbol files from http://adcdownload.apple.com/Developer_Tools/watchOS_13S5255d/Watch1_1_13S5255d.dmg. I was successful to launch my watchOS app by following steps.
- Download the symbol file installer for 13S5255c from http://adcdownload.apple.com/Developer_Tools/watchOS_13S5255c/Watch1_1_13S5255c.dmg.
- Create directory "~/Library/Developer/Xcode/watchOS DeviceSupport/2.0 (13S5255d)/Symbols"
- Mount the DMG and open Watch1,1.pkg.
- Change the destination directory to above directory. (DO NOT install to default location! OS X will be destroyed!)
- Install symbol files.
- Open project on Xcode 7 beta.
- Disconnect and connect iPhone.
