Description

The IsSpellCheckEnabled and IsTextPredictionEnabled properties on input controls such as Entry do not behave consistently across platforms.

On Android and Windows:

• The properties sometimes work as expected—enabling spell check suggestions and text prediction.
• However, when IsSpellCheckEnabled is set to true, the system may autocorrect misspelled words instead of showing a squiggly underline, which is not the expected behavior. This reduces user control and can lead to unintended text changes.

On iOS and Maccatalyst:

• Toggling IsSpellCheckEnabled and IsTextPredictionEnabled has no observable effect.
• No spell check underlines or predictive suggestions appear.

• Set up the Switch to toggle both IsSpellCheckEnabled and IsTextPredictionEnabled on the Entry.
• Run the app on the following platforms: Android, Windows, iOS, and MacCatalyst.

Test input behavior:

• Type misspelled words into the Entry control.
• Observe if spell check squiggly underlines appear for misspelled words
• Observe if text prediction suggestions are provided.
