Xcode 8.3 - SourceKitService CPU 95%+ loads

Hi all iOS developer buddies, I updated my Xcode to 8.3 yesterday. And start from then, my MacBook fans kept running continuously. I opened 'Activity Monitor' and found that the SourceKitService took 95%+ to 130%+ CPU load. But I didn't even build my xcode project, I just opened it for code referencing (for Android).

Does anyone have any idea, how to tweak the settings to lower the CPU load?

I found out the problem and fixed it finally.

If you upgraded your Mac SSD(In my case, I brought a OWC Aura SSD for my late 2013 mbp.), you need to check if TRIM is enabled or not.

You can enable it by typing sudo trimforce enable in Terminal.

Me too ~

When I encounter this problem.

I found that there are multiple threads SourceKitService .

Kill the SourceKitService thread that use CPU higher.

And then clean the xcode project and clean Build Folder.

solved

This is not unusual, Xcode indexes your source files in the background when you open the project. If the CPU load did not stop, file a bug report on https://bugreport.apple.com and attach a sysdiagnose.
