SwiftUI 调用 AR Quick Look 打开AR模型
1.您应该通过Xcode重写。
2.swift playground 打开，需要上传到 test flight 才能正常使用。

代码1
import SwiftUI
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
代码2
import SwiftUI
struct ContentView: View {
@State var ARshow = false
var body: some View {
ARShow(ARImage: "tutorial", ARText1: "1.1", ARText2: "tutorial", ARName: "tutorial", ARshow: ARshow)
//你只需要一行代码即可打开AR模型
//You only need one line of code to open the AR model
//ARShow(
}
}
