SwiftUI Expanding TextEditor
Rehmat Singh Gill
I am a Flutter developer learning SwiftUI. I am working on a ChatGPT clone app in SwiftUI and trying to recreate the expanding TextEditor. I have tried many approaches mentioned in various articles, but all of them feel like a cheap workaround. The closest I have come is using a TextField with the following method:
TextField("What's up?", text: $text, axis: .vertical)
.lineLimit(1...5)
However, I am unable to use the Enter button to create a new line in the TextField, which I believe is the reason TextEditor exists.
This is the view I am trying to recreate:

You can stop the "return" key from dismissing the keyboard by adding the submitScope modifier.
TextField("What's up?", text: $text, axis: .vertical)
.submitScope()
.lineLimit(1...5)
By default, tapping the "return" key creates a "submit" action and dismisses the keyboard, and you can handle this using onSubmit { ... }. If you add .submitScope(), there is no "submit" action, and so a new line is inserted.
