The error Method definition for 'uptimeMilliseconds' not found randomly showed up while I was programming with Swift on the newest Xcode Beta (Beta 4). I was working fine and compiling up to this point, but this error randomly occurred.
I'm using Pods and this error showed up in GoogleDataTransport/GDTCORClock at @implementation GDTCORClock.
Has someone experienced the same issue or does someone know what causes this and how to fix it?

    I added the "xcode12" tag, since this question is specific to the Xcode 12 beta build. (Unfortunately there is no "xcode12beta" tag). – Duncan C Aug 05 '20 at 18:36

    Please edit the question to show the complete code where you see this. What you have right now is not enough information. – Doug Stevenson Aug 05 '20 at 18:47
  • Solved: two Pods weren’t working with each other/ weren’t updated for Xcode12 beta – gozzomain Aug 06 '20 at 19:05
  • @gozzomain How did you determine the Pods weren't and weren't updated? Were you able to resolve this by updating the Pods? I am having the same error suddenly. – gohnjanotis Aug 07 '20 at 18:12
  • I remembered the last pod I added and removed that one. Pure luck... – gozzomain Aug 08 '20 at 20:55

I was experiencing this same issue, even when trying to build in the newest non-beta version of Xcode.

I was able to solve it by doing the following:

  • delete the Pods folder
  • delete the *.xcworkspace file
  • delete the Podfile.lock file
  • run pod install
