iOS 真机调试出现：“Please verify that your device’s clock is properly set, and that your signing certificate is not expired. (0xE8008018).”错误。
Solution within Xcode: In Xcode, go to Preferences --> Accounts --> View Details Press the refresh button in the lower left corner (called Download all in Xcode 7)
Sometimes it may also help to delete invalid provisioning profiles: right-click -> move to trash I saw this error exactly one year after signing up as an Apple developer.
知道有人看不懂，哈哈哈 意思就是让你去view Details refresh一下！
