I've found that form inputs are clearing themselves on focus when building for iOS, but I do not have this problem in the browser. Example:

let PageBody = (
 <div>
 <h1>Form</h1>
 <br />
 <form>
 <p>Input: <input type="text" maxLength="100" name="someData" id="someData" /></p>
 <p><input type="button" id="SaveButton" name="SaveButton" value="Save" /></p>
 </form>
 </div>
);

I believe this is happening at the JavaScript layer, because adding an empty onFocus="" resolves the issue, preserving the value that was in the input.

Any thoughts on where this coming from or next steps in debugging?

Edit:

I removed the onFocus="" to continue tinkering and (frustratingly) I can no longer reproduce the issue.

  Please provide a more complete example, with yours onChange, onFocus .etc events. Or your input is totally uncontrolled ?

  That is the strange part, I have no event listeners on that field.

  then, what is its purpose ? what do you want to perform with ? have you read differences between controlled and uncontrolled inputs from React doc ?
