Xcode compile time too long



I know this question doesn’t belong here but I need help to figure out a solution to this problem because Apple support hasn’t responded since almost 3 months.

Version 9.2 beta (9C34b)
MacBook Pro (13-inch, Early 2011)
macOS HighSierra version 10.13.1 (17B48)

Every time I compile a program in Xcode it takes atleast 7 minutes to simulate the application. Around 90% of attempts, the program doesn’t even compile inspite of generating a successful build. Common error messages that show up are the following :
Timed out waiting for the simulator application for iphonesimulator to become ready
Could not attach to pid : "1050"
Failed to initiate service connection to simulator

Can anyone please help me ?

Warm regards.


I guess the problem you met is related to the newest MacOS, but I’m not sure about it since I don’t use Xcode to program. Had Xcode worked well before you updated to Mac HIgh Sierra? When I used Android Studio at first, I had trouble as well. The AVD manager didn’t work for failure of installing HAXM which is imcompatible with Mac High Sierra. Fortunately, I searched solutions online and finally found the newest version of HAXM. Now it has been working well with my MBP. These imformation I mentioned above seems useless to solving your problem, but I wish you could find the right way to handle it.
best regards.


@kafka : Thanks for taking the time to answer my question. Unfortunately I had the same problem before updating my OS to MacOS High Sierra. In fact I was hoping the move to MacOS High Sierra would solve the issue. I created a bug report on the Apple Developer Support system and even sent them my sysdiagnose. It has been 3 months and they haven’t responded yet. It is very frustrating because I am spending more time on sorting that problem out and not on the actual coding. All the best and warm regards.



Hi. This is way too long to be stumped like this. Did you try some google-fu? I’m yet to dig into swift development, but was searching for Xcode compile tricks and came across your issue.

Have you seen any of these?



What appears to be happening is that the process number is already running. You said this was on a laptop? Do you restart that machine ever? It almost seems as if you have a zombie process running from an earlier version of Xcode.

You can try to see if the process is simply running already by:

ps -p 1050 in a terminal
If it is go ahead and kill -9 1050


Hello Boredomdenied,

Sorry for the delay in replying. Thanks for taking the time to answer my question.

I have restarted the machine as well as tried other solutions suggested on stackoverflow with no success. I was so fed up of the absence of support from Apple that I switched to Kivy to program applications for iOS. I might come back to retry the solutions proposed in the links you have shared but for the moment, I really am not in a position to waste any more time on Apple’s Xcode.

Thank you anyways.
