[iOS] DatePicker | Remove unnecessary UpdateDate() call in UpdateTextColor() #27811

bhavanesh2001 · 2025-02-14T19:41:47Z

Description of Change

This change removes an unnecessary call to UpdateDate() from UpdateTextColor() for iOS.

Root Cause

UpdateTextColor() was incorrectly triggering UpdateDate(), which overrode the expected locale-based date format with the virtual view's default format
As a result, the DatePicker initially displayed the wrong format instead of following the device's locale settings
However, text color updates do not require a date update, and this call was redundant.

Fix

Removed the unnecessary UpdateDate() invocation inside UpdateTextColor().
Verified that text color changes are still applied correctly without triggering UpdateDate().

Issues Fixed

Fixes #27803

rmarinho

The comment does say it was needed. Can you add a test where changing the color will still update on the UI?

bhavanesh2001 · 2025-02-15T05:11:16Z

@rmarinho I added a test. However , text color is a styling property, and Appium does not provide a way to verify it directly. The current test confirms that the binding updates correctly, but it does not guarantee that the UI visually reflects the color change.
If i'm missing something here please let me know. That said, the UI is updating as expected.

Edit: Never mind I figured it's need to be verified comparing snapshots.

@jfversluis Could you run pipelines?

The DatePicker seems inconsistent on Mac. The TextColor property definitely isn't working. Check #20904

Are you able to wrap the whole file with a #if TEST_FAILS_ON_CATALYST?

See

maui/src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue9794.cs

Line 1 in 0dde841

#if TEST_FAILS_ON_CATALYST // This test fails on catalyst, unable to click the back button as its does not have an identifier.

I am not sure if we have something that is watching files for these lines to give us stats or something. AI or someting maybe.

Code looks good. Nice test.

I think there may be some tech involved with the way to exclue failing tests on some platforms. Added a comment.
