Found the solution. Apparently this is a known (SR-13343) in Xcode 12. It has to do with "SwiftPM binaryTarget dependency and code signing", where Xcode fails to sign the frameworks that are provided by SwiftPM.
See this link: https://forums.swift.org/t/swiftpm-binarytarget-dependency-and-code-signing/38953
If you read thru you will find a link to the work around, by adding a script to the build phase of the target:
Work Around Link: pspdfkit.com/guides/ios/current/knowledge-base/library-not-found-swiftpm/
I just added the script to my app, everything is now good!

Xcode 12 beta 3: ColorPicker won't run on Simulator, so run it on your device.
struct ContentView: View {
@State private var drawSwiftUIColor: Color = Color.red
@State private var drawOpacity: Double = 1.0
@State private var drawUIColor: UIColor = UIColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 1.0)
@State private var drawHexNumber: String = "#FF0000"
var body: some View {
VStack {
Spacer()
ColorPicker("", selection: $drawSwiftUIColor, supportsOpacity: true)
.scaleEffect(2)
.offset(x: 28 - UIScreen.main.bounds.width, y: -15)
.onChange(of: drawSwiftUIColor) { newValue in
getColorsFromPicker(pickerColor: newValue)
}
// Use this only if you are initializing the picker with UIColor, otherwise delete the onAppear()
.onAppear() {
//resetColorPickerWithUIColor()
}
Spacer()
Text("SwiftUI Color").bold().foregroundColor(drawSwiftUIColor).opacity(drawOpacity)
Text("UI Color").bold().foregroundColor(Color(drawUIColor))
Text("Hex Number: \(drawHexNumber)").bold()
}
}
func getColorsFromPicker(pickerColor: Color) {
let colorString = "\(pickerColor)"
let colorArray: [String] = colorString.components(separatedBy: " ")
if colorArray.count > 1 {
var r: CGFloat = CGFloat((Float(colorArray[1]) ?? 1))
var g: CGFloat = CGFloat((Float(colorArray[2]) ?? 1))
var b: CGFloat = CGFloat((Float(colorArray[3]) ?? 1))

Can confirm!
Actually "Sign In With Apple" in general does not run on iOS 14 Simulators. I have a full blown "Sign In With Apple" with backend server that runs smoothly on all iOS 14 DEVICES, but not the Simulator.
iOS 14 Simulators, once you sign in to Apple account in the Settings, you can not Sign Out!!!!
