I am making a program that will need to compare 2 characters. It would take the last character of the first word and check to see if it is the same as the first character in the second word. I have code that seems to be correct so not really sure where to go from here. The function I feel that is in question is wordChained()->Bool.
struct GameView: View {
@State var score = 0
@State var health = 3
@State private var playerWord = ""
@State private var prevWord = ""
@State private var usedwords = [String]()
var body: some View {
ZStack{
LinearGradient(gradient: Gradient(colors: [Color.red, Color.orange]), startPoint: .top, endPoint: .bottom)
.edgesIgnoringSafeArea(.vertical)
VStack{
HStack{
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
}
HStack{
HStack{
Text("Score:")
Text(String(score))
}.padding()
HStack{
Text("Health:")
Text(String(health))
}
}
Spacer()
Spacer()
VStack {
if health == 0{
NavigationLink(destination: MenuView().navigationBarTitle(Text("x")).navigationBarHidden(true)){
Text("YOU LOSE | GO TO MENU").padding()
.border(Color.black, width: 2)
.scaleEffect(0.8)
.accentColor(Color.black)
}
}
else{
TextField("Enter a Word", text: $playerWord, onCommit: addNewWord) //<- No `()->Void` here
.padding()
.border(Color.black, width: 2)
.scaleEffect(0.8)
}
List(usedwords, id: \.self){
Text($0)
}
}
Spacer()
HStack{
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
}
}
}
}
func addNewWord(){
let answer =
playerWord.lowercased().trimmingCharacters(in: .whitespacesAndNewlines)
guard answer.count > 0 else {
return
}
if isValid(possibleWord: answer){
score += 1
usedwords.insert(answer, at: 0)
prevWord = answer
playerWord = ""
}
else{
health -= 1
playerWord = ""
}
}
func getWords() -> [String]?{
var arrayOfStrings: [String]?
do {
// This solution assumes you've got the file in your bundle
if let path = Bundle.main.path(forResource: "english3", ofType: "txt"){
let data = try String(contentsOfFile:path, encoding: String.Encoding.utf8)
arrayOfStrings = data.components(separatedBy: "\n")
}
} catch let err as NSError {
// do something with Error
print(err)
}
return arrayOfStrings
}
func wordChained() -> Bool{
let char1 = prevWord[prevWord.index(prevWord.startIndex, offsetBy: prevWord.count - 1)]
let char2 = playerWord[playerWord.index(playerWord.startIndex, offsetBy: 0)]
if char1 == char2{
return true
}
else{
return false
}
}
func isValid(possibleWord: String) -> Bool{
let wordList = getWords()
if ((wordList?.isEmpty) != nil){
if wordList!.contains(possibleWord){
return true
}
else{
return false
}
}
else{
if wordList!.contains(possibleWord) && wordChained(){
return true
}
else{
return false

I cannot find a way to fix this error. I have seen posts about a similar problem but I cannot make any correlations.
I am trying to take the input from a textfield, putting it in an array and displaying it in a list.
struct GameView: View {
@State var score = 0
@State private var playerWord = ""
@State private var usedwords = [String]()
var body: some View {
ZStack{
LinearGradient(gradient: Gradient(colors: [Color.red, Color.orange]), startPoint: .top, endPoint: .bottom)
.edgesIgnoringSafeArea(.vertical)
VStack{
HStack{
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
}
HStack{
Text("Score:")
Text(String(score))
}.padding()
Spacer()
Spacer()
VStack {
TextField("Enter a Word", text: $playerWord, onCommit: addNewWord()->Void)
.padding()
.border(Color.black, width: 2)
.scaleEffect(0.8)
List(usedwords, id: \.self){
Text($0)
}
}
Spacer()
HStack{
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
Image("chain").scaleEffect(1.3)
Image("chain").scaleEffect(1.3).rotationEffect(Angle(degrees: 90))
}
}
}
}
func addNewWord(){
let answer =
playerWord.lowercased().trimmingCharacters(in: .whitespacesAndNewlines)
guard answer.count > 0 else {
return
}
usedwords.insert(answer, at: 0)
playerWord = ""
}
