XCode 9.3 breaks playground

I just upgraded from XCode 9.2 to XCode 9.3. Since then my playground is very unresponsive/slow, animations play at unexpected times and UIKit elements are not properly layouted anymore.

Are there any known issues and/or fixes that I can apply?

Xcode 9.3.1 has just been released (10 May 2018) and is supposed to fix 'an issue that caused Xcode to slow down when editing a playground'.

Had same issue and there was no way around it. People filed bugs as far back as April 8th.

Best solution is to download Xcode 9.4 Beta from Apple Developer Page.

This worked for me and CPU usage is low and Xcode doesn't crash on playgrounds anymore.

Kill "homed"

My experience is that homed is going nuts, hogging the CPU.

Without quitting the Playground app, you can go into Activity Monitor (Applications > Utitlities > Activity Monitor) and sort by %CPU, you might see Process Name homed taking a large CPU load. Double clicking on homed and selecting Quit does not seem to harm the workings of the playground.

If you still encounter problems, you could close the Playground app, and use the same process to force quit com.apple.CoreSimulator.CoreSimulatorService, although doing that requires a lengthy process when you restart your Playground.

Playgrounds have been buggy all along but 9.3 takes it to another level. Have you noticed a “diagnosticd” process taking up much of the cpu while running playgrounds? I suspect that this may be in part responsible for the lack of performance. Not much to do until Apple gets their act together (if ever)
