The compiler is unable to type-check this expression in reasonable time in Xcode 12 with SwiftUI Error in SwiftUI

Firstly, sorry for my english, thats not the best, but I will try my best.

I would like to develop a Swift UI app (im beginner) on a virtual machine (XCode version: 11.7, OS: macOS Catalina version 10.15.6.) I gave the virtual machine 8 giga ram and 2 core resources. As the code grew, XCode became slower and slower. Due to the above error, the code doesn't even build anymore.

The error: The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions.

What exactly could be causing the error? Do u have any tips, how I can increase the speed of XCode and avoid that error? I would be very grateful if someone could help me with this problem

Code:

import SwiftUI

public struct ClockView: View {
    
    var width = UIScreen.main.bounds.width
    
    public var body: some View {
        ZStack {
            Circle()
                .fill(Color.gray).opacity(0.2)
            
            ForEach(0..<60) { idx in
                VStack {
                    Rectangle()
                        .fill(Color.primary)
                        .opacity(1)
                        .frame(width: 2, height: idx % 5 == 0 ? 15 : 6)
                    Spacer()
                }
                .rotationEffect(.degrees(Double(idx) * 6))
            }
            
            Spacer(minLength: 0)
            
            ForEach(1..<13) { idx in
                VStack {
                    Text("\(idx)")
                        .font(.system(size: 25))
                        .offset(y: 12)
                        .rotationEffect(.degrees(-Double(tick)/12 * 360))
                    Spacer()
                }
                .rotationEffect(.degrees(Double(idx) * 30))
            }
            
            Spacer(minLength: 0)

                .offset(y: (width - 160) / 4)

                .offset(y: (width - 180) / 4)

            /*hour*/
            Rectangle()

                .fill(.primary)
                .frame(width: 8, height: 8)
            Circle()

                .frame(width: 4, height: 4)
            
        }.frame(width: width - 80, height: width - 80)  /*!!!error here!!!*/
    }
