Type-check error in Xcode 12: "The compiler is unable to type-check this expression in reasonable time"

I have updated my Xcode to version 12 few days ago. When I opened one of my existing projects the new Xcode is presenting the error:

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

The project was working fine in the previous version.

Here is my code where I get the error:

    import SwiftUI

struct FaqView: View {
    @ObservedObject var viewModel = FaqViewModel()
    @State var sectionState: [String: Bool] = [:]
    
    init(){
        UITableView.appearance().backgroundColor = .init(red: 255, green: 255, blue: 255, alpha: 0.0)
        UITableViewCell.appearance().backgroundColor = .init(red: 255, green: 255, blue: 255, alpha: 0.0)
    }
    var body: some View {
        GeometryReader { geometry in

If anyone has experienced with this error please help. Thanks in advance.
