the textview will crash app

[michaelzhuang06]

I placed two textviews in two different view, and somehow one of textview is fine, but the other one will crash app when open the view.

Can you show me your code?

[michaelzhuang06]

Sure, here is the code that crash app in simulator

…

----------------------------------------------------------- @State private var isEditing:Bool = true @State private var str_title: String = “" @State private var str_content: String = “" var body: some View { VStack(alignment:.leading){ Text("Title").lineSpacing(10).padding(10) TextField("Placeholder", text: $str_title) .onAppear{ self.str_title = “test title." } .textFieldStyle(RoundedBorderTextFieldStyle()) .autocapitalization(.none) .font(.system(size: 20)) .lineSpacing(10) .padding(10) Text("Detail").lineSpacing(10).padding(10) TextView( text: $str_content, isEditing: $isEditing, placeholder: "" ).onAppear{ self.str_content = “hello, test" } }.frame(height: 100) //there are some other code like Button Click action } ———————————————————————————— The result was : ” Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)” I used swiftUI, Xcode 11.4 In other view, I use almost same code and it is working fine. The app was crash when presented to this view. It took me half day to figure out it was the textview because I can’t locate the detail line and I didn’t expect it was textview, everything will work fine if I disable textview or replace textfield with textview. And I was disable other code in the same view first and still crash until I disable textview. Hope it will help. Thanks Michael

I don't see two TextViews in that view. If you could share your repository I could take a look and see what the issue is.

[michaelzhuang06]

The code of the other view is almost same —————————— TextView( text: $str_content, isEditing: $isEditing, placeholder: messageinfo.messagecontent ).onAppear{ self.str_content = self.messageinfo.messagecontent }.frame(height: 100) —————————--- But the view never cause crash, and this view was show by NavigationLink Thanks Michael
