You may also find that XCode updates a ton of config files when updating options. You only have to use XCode to set up the extra config for certain 3rd party packages - use VSCode for all Flutter code.
#Xcode ide for mac ios emulator android#
Oddly, running activity monitor (or top), I can't really see what is seizing all the resources. XCode is the iOS IDE and Simulator is like the Android emulator but for iOS. I'm hoping Apple can tune a future version for better foreground performance, otherwise they should explicitly warn and specify when/where more CPU GHz/Cores/RAM are needed. No other apps running but Finder and Dropbox.
This with a simulator open but no app running, or even no simulator opened.
Even just clicking Xcode in the dock does nothing for long periods. Sometimes I get impatient and click the file again and moments later the file opens in a new window (false double-click). I click a file in my project tree and sometimes the editor opens immediately, sometimes nothing happens for 5, 10, even 30 seconds. My pitiful late 2014 Mac Mini (i5M and 8GB, plenty of magnetic disk space) was fine until Xcode 9, now I'm using Xcode 10.2 and build times for a medium iOS project are slow but bearable, however Xcode's normal background activities seem to be crippling its UI much of the time. Memory is vital (16GB SHOULD be enough for any app not explicitly calling for more in its requirements).
