[0.76.4] TextInput issue - TypingAttributes

[gaeldestrem]

Environment

react-native -v: 15.0.1
npm ls react-native-macos: : 0.76.4
node -v: 18.20.5
npm -v: 10.8.2
yarn --version: 1.22.1
xcodebuild -version: Xcode 16.1 (Build version 16B40)

Steps to reproduce the bug

I am trying to update my project from 0.75.3 to 0.76.4 as I am really excited about the new Fabric changes that got merged (Thank you for it 🙌).

I encountered the following error when starting :

Error Thread 1: "-[RCTUITextField typingAttributes]: unrecognized selector sent to instance 0x1243e8000"



I managed to reproduce the error with a simple <TextInput value={value} onChangeText={onChangeText} />

By digging into the react-native code, I found that the issues comes the line _originalTypingAttributes = [_backedTextInputView.typingAttributes copy];. The object seems undefined and replacing it by an empty dictionary allows the application to start.

I also found a related issue when typing into the TextInput :

FAULT: NSInvalidArgumentException: -[RCTUITextField setTypingAttributes:]: unrecognized selector sent to instance 0x129a1e320; (user info absent)

Commenting the following code prevents this error:

Here is my patch-package (some changes are specific to my project) : react-native-macos+0.76.4.patch

HI, I want to note that Fabric on React Native macOS is not ready as of 0.76. I have.. much work going to get it ready, but I wouldn't use it in production yet. That being said, I really appreciate these bug reports, so thank you!

Hi, I want to confirm an issue regarding the new architecture (new arch). React Native in version 0.76.0 has enabled the new architecture by default, but Fabric for react-native-macos in version 0.76.0 is not yet ready. Does this mean that it is currently not recommended to enable the new architecture in production for any version of react-native-macos?

@bear-ei yes, it's not ready on React Native macOS yet.

Alright. Thank you for the response. Looking forward to the new architecture being ready soon.
