not only that but a new instance is created every time xcode quits and restarts. each instance runs at min 100% cpu constantly even when xcode quit.
my batter has been draining super fast since the last xcode update. xcode is listed under Using Significant Energy all the time, even when idle in background. and even after quitting. I thought this might just be stale information but my activity monitor shows xcode as using 8,778 power in the last 12 hours even tho i quit it last night.
swift-frontend doesn't show power usage. but in the CPU usage i saw 3 instances of swift-frontend each running above 100% CPU. i force quit them and xcode finally disappeared from the USP list.
