SwiftUI TextField height shrinks on first focus in iOS 26/Xcode 26

Hi Everyone,

I’m encountering a layout issue in SwiftUI starting with iOS 26 / Xcode 26 (also reproduced on iPadOS 26). I would like to see whether anyone else has seen the same behaviour, and if there’s any known workaround or fix from Apple.

Reproduction

• Minimal code:

  struct ContentView: View {
      @State private var inputText: String = ""
  
      var body: some View {
          TextField("", text: $inputText)
              .font(.system(size: 14, weight: .semibold))
              .background(Capsule().foregroundStyle(.gray))
      }
  }
  

• Environment:

  • Xcode: 26.1 (17B55)
  • Devices / Simulators: iOS 26.0, iOS 26.0.1, iOS 26.1 on iPhone 17 Pro Max; iPadOS 26 on iPad.
  • OS: iOS 26 / iPadOS 26

Observed behaviour

• When the TextField is tapped for the first time (focus enters), its height suddenly decreases compared to the unfocused state.
• After this initial focus-tap, subsequent unfocus/focus cycles preserve the height (i.e., height remains “normal” and stable).
• Prior to iOS 26 (i.e., in older iOS versions) I did not observe this behaviour — same code worked fine.
• I have not explicitly set .frame(height:) or extra padding, and I’m relying on the default intrinsic height + the Capsule background.

Work-arounds

• Adding .frame(height: X) (fixed height) removes the issue (height stable).

Thanks in advance for any feedback!
