After looking at Caleb Jones's comment, I found that disabling autocorrection on the textfield in swiftui stops crashes entirely.
The main issue is probably because MacCatalyst doesn't support predictive text, but iOS/iPadOS does due to the virtual keyboard. Disabling autocorrection disables predictive text.
Here's my code with the fix:
import SwiftUI
import WebKit
struct ContentView: View {
@State var textObject: String = ""
var body: some View {
ZStack {
WebView(url: URL(string: "https://google.com")!)
TextField("", text: $textObject)
.background(
Rectangle()
.foregroundColor(.black)
)
.disableAutocorrection(true)
}
}
}
struct WebView: UIViewRepresentable {
var url: URL
func makeUIView(context: Context) -> WKWebView {
return WKWebView()
}
func updateUIView(_ webView: WKWebView, context: Context) {
let request = URLRequest(url: url)
webView.load(request)
}
}
