Xcode 11.3 - getting hanged & responding very slow

Question

We are using Mac OS - Catalina and XCode Version - 11.3.

After OS and Xcode update, Xcode is responding very slow. Also it takes too much time to run application, sometimes in hours.

Application run process on device is very slow and on simulator, it always gets hanged.

Our System Configuration is:-

OS Version: 10.15.2 (19C57)

Mac Mini: Mac mini (Late 2012)

Processor: 2.5 GHz Dual-Core Intel Core i5

Memory: 8 GB 1600 MHz DDR3

Graphics: Intel HD Graphics 4000 1536 MB

We are using Swift 4.2 for development.

Please suggest us any solution which can improve this slow performance.

Answer 1

8 GB RAM available : that's probably the problem with incessant memory swap.

Should increase to 16 GB at least.

If you have a look at Activity Monitor does that show SourceKitService hogging the CPU and are your fans running flat out?

Answer 4

I'm getting the same issue. Profiling Xcode in instruments seems to show that some stuff in AppKit is hanging the main thread way longer than it should be. I'd bet there was a change in AppKit shipped with MacOS 10.15.3 that is causing this. Probably a new bug. Really frustrating. I hope we aren't waiting too long for a fix for this.
