[Help Wanted] How to remove TextField's intrinsic background in .glassEffect on watchOS 26?

English Version

Hello everyone,

I'm a high school developer. With the release of the brand new watchOS 26 last week, I've updated to Xcode 26 and started adapting my app. I've immediately hit a frustrating UI problem with TextField.

My Goal:
I want to create an input component with a .glassEffect, where the TextField sits transparently on the glass background.

The Problem:
I've applied the .glassEffect(.clear) modifier to a parent HStack. However, the TextField component itself appears to ship with a new, non-removable default gray background style in watchOS 26. This background seems to be an intrinsic part of the component, floating on top of my glass view. This creates an ugly "double-border" effect that completely ruins the intended aesthetic.

My Questions:
Given that watchOS 26 and Xcode 26 were just released, there's very little documentation or community discussion available yet.

1. Is this new default background an intentional design choice for TextField in watchOS 26, or is it likely a bug in this initial release?
2. If this is by design, is there a new, official way to override this intrinsic styling to make the TextField fully transparent, especially when used within a .glassEffect container?

Any help would be greatly appreciated. Thank you!

大家好！

我是一名高二的开发者。就在上周苹果发布了全新的 watchOS 26 系统，我第一时间更新了 Xcode 26 并开始适配我的 App，但马上就遇到了一个关于 UI 的棘手问题。

我的目标：
在 watchOS 26 上，我想实现一个带有 glassEffect（玻璃效果）的输入框，让 TextField 完全透明地融合在玻璃背景之上。

遇到的问题：
我为一个 HStack 容器应用了 .glassEffect(.clear) 修饰符，但 TextField 这个输入文本框组件本身，似乎在 watchOS 26 上被��予了一个无法直接移除的、默认的灰色背景样式。这个背景看上去是组件自带的，它悬浮在通透的玻璃效果之上，形成了一个很难看的“双重边框”，完全破坏了设计感。

我的问题：
由于 watchOS 26 和 Xcode 26 都是刚刚发布，相关文档很少，所以想请教大家：

1. TextField 这个新的默认背景是 watchOS 26 有意为之的设计，还是一个初期版本的 Bug？
2. 如果这是新设计，是否有新的 API 或样式可以覆盖（override）这个自带的背景，让它在 glassEffect 中实现完全通透？

非常希望能得到大家的指点。提前感谢各位！

I've run into a SwiftUI layout issue that I've been struggling with all night, and I would greatly appreciate your help.😭

This is very likely an intentional decision on their end. Because Apple seems to been enforcing a system material background for readability. I doubt theres currently a public modifier to remove it so a custom wrapper is probably the only workaround for now.

[Eric-Terminal]

No problem, I’ve already solved it.😋

1. Hi I need help with finding the code in videos or pictures
   please.

[Eric-Terminal]

Sorry, I may not have understood what you meant. What do you mean by finding the code from videos or pictures? Do you mean locating the implementation of the UI shown in the image I sent within my repository?

[birdmoozy]

Kind of .I mean the code you'd write for a link but it's in pictures...ect . I can't find it . My schooling explained it ,I did it but it did nothing, so I looked it up on online and I plan can't find it .
I don't know if it helps but Im using a tablet to code.
Wold a computer work better?
thank you for responding 😀.
Ps .your picture is cool .

It sounds like you are trying to display an image using code (like in HTML or Markdown) but it's not showing up. Here are the two most common ways to do it:

1. If you are learning HTML:
   You use the <img> tag. It looks like this:
   <img src="https://example.com/your-image-link.jpg">

2. If you are using Markdown (like here on GitHub or Discord):
   You use this format:
   !(https://example.com/your-image-link.jpg)

A quick tip: The reason it might have done "nothing" for you before is probably because of the link you used. The link needs to be a direct URL to an image hosted online on the internet. If you just put a path to a photo saved locally in your tablet's photo album, it won't work on a website!

And to answer your question: Yes, a computer would absolutely work 100% better for coding than a tablet!
Typing on a real keyboard is much faster, you can manage files much easier, and you can install proper coding tools. If you can get your hands on a computer, your coding life will be much happier.

Good luck with your schooling and your coding journey!

Thankyou it worked!

Hi Eric,

I’ve been experimenting with watchOS 26 too, and I ran into the same issue. The gray background on TextField is intentional in watchOS 26 — Apple seems to have added an intrinsic background for consistency across apps, so it’s not a bug.

The good news is you can override it to make your TextField fully transparent on a .glassEffect container. Here’s what works:

TextField("Message...", text: $viewModel.userInput)
.textFieldStyle(.plain) // removes default fancy styling
.background(.clear) // makes the TextField itself transparent
.labelsHidden() // hides any system-added labels

The key is using both .textFieldStyle(.plain) and .background(.clear) — just one of them alone doesn’t fully remove the background in watchOS 26.

Then, your parent HStack with .glassEffect(.clear) will show through cleanly, and you won’t get the double-border effect anymore.

So yes, it’s by design, but with these modifiers, you can achieve the look you want.

Hope that helps!

Thank you very much for your suggestion. Although it might not be necessary anymore… in the earlier replies I shared a screenshot showing that I had already reshaped the text field into a capsule style, which actually fits my UI quite well 😋.

Back in September I had just started learning Swift and wasn’t very familiar with it yet, but I truly appreciate your advice now. I’ll definitely remember this approach for the future.
