Quick Xcode Question:

I have made a loading screen for my app. The goal is that it appears for $10$ secs before going to the contentView, in addition the in the loading text to have an animation for three periods to have a different display configuration every seconds. How do i achieve this? Code Below: import SwiftUIimport AVFoundationstruct LoadingView: View $\{$ @State private var isLoading $=$ true @State private var loadingText $=$ "Loading..." @State private var colors: $[$Color$]=[]$ @State private var timer $=$ Timer.publish$($every: $1,$ on: $.$main, in: $.$common$).$autoconnect$()$ @State private var currentIndex $=0$ @State private var showDots $=$ true $//$ State to control visibility of dots @State private var audioPlayer: AVAudioPlayer? var body: some View $\{$ ZStack $\{$ LinearGradient$($gradient: Gradient$($colors: colors$),$ startPoint: $.$topLeading, endPoint: $.$bottomTrailing$).$animation$(.$easeInOut$($duration: $2)).$edgesIgnoringSafeArea$(.$all$)$ VStack $\{$ Spacer$()$ Spacer$()//$ Spacer to push text to the bottom third Text$($loadingText$).$font$(.$system$($size: $30))//$ Cut the size in half $.$foregroundColor$(.$black$)//$ Make it black $.$opacity$($loadingText$.$isEmpty $?0$ : $1).$animation$($Animation$.$easeInOut$($duration: $0\mathrm{.}5).$repeatForever$())$ Spacer$()\}\}.$onReceive$($timer$)\{\_$ in if currentIndex $<$ loadingText.count $\{//$ Check if character is a dot and toggle visibility if loadingText$[$loadingText$.$index$($loadingText$.$startIndex, offsetBy: currentIndex$)]=="."\{$ showDots.toggle$()\}$ currentIndex $+=1\}$ else $\{$ currentIndex $=0$ loadingText $=$ "Loading..." $\}\}.$onAppear $\{$ setupColors$()$ playSound$()$ DispatchQueue.main.asyncAfter$($deadline: $.$now$()+3)\{$ isLoading $=$ false $\}\}.$fullScreenCover$($isPresented: $isLoading, content: ContentView.init$)\}$ private func setupColors$()\{$ var randomColors: $[$Color$]=[]$ for $\_$ in $0..<8\{$ let red $=$ Double.random$($in: $0..\mathrm{.}1)$ let green $=$ Double.random$($in: $0..\mathrm{.}1)$ let blue $=$ Double.random$($in: $0..\mathrm{.}1)$ randomColors.append$($Color$($red: red, green: green, blue: blue$))\}$ colors $=$ randomColors $\}$ private func playSound$()\{$ if let soundFilePath $=$ Bundle.main.path$($forResource: "loadingSound", ofType: $"$mp$3")\{$ let soundFileURL $=$ URL$($fileURLWithPath: soundFilePath$)$ do $\{$ audioPlayer $=$ try AVAudioPlayer$($contentsOf: soundFileURL$)$ audioPlayer?.prepareToPlay$()$ audioPlayer?.numberOfLoops $=-1$ audioPlayer?.play$()\}$ catch $\{$ print$("$Error loading sound file: $\backslash ($error$.$localizedDescription$)")\}\}$ else $\{$ print$("$Sound file not found"$)\}\}\}$struct LoadingView$\_$Previews: PreviewProvider $\{$ static var previews: some View $\{$ LoadingView$()\}\}$
