macOS Big Sur and Xcode 12.2

Hi,

I upgraded my iMac OS from Catalina to Big Sur and Xcode to 12.2. My machine is very slow now and it's hard to open an Xcode project. All the junks were cleaned but the issue is not yet resolved. Please help me on this.

Below I have mentioned my iMac configurations.

iMac Retina 4K, 2017
Processor : 3.4 GHz Quad-Core Intel Core i5
Ram : 8 GB 2400 MHz DDR4
Storage : 1 TB Fusion Drive ( 463 GB available )
macOS Big Sur and Xcode 12.2
