# Steps to reproduce

Set the text color property of a UITextView to any other color than the default black, either via a storyboard or programmatically:

    NotesText.TextColor = UIColor.White;
    NotesText.Text = "Foo";

# Expected behavior

Text color should be white.

# Actual behavior

Text color remains unchanged, or so it seems. If you switch the statements by settings the text first, and color second, it somehow works!

    NotesText.Text = notes;
    NotesText.TextColor = UIColor.White;

I think that when loading the view from a storyboard, text color is always set first, so the bug manifests.

Tested on iPhone 4s, iOS 9.3 (13E233), I've had reports of this happening on iPhone 5 as well.

Hello I remember this happening because the selectable property in UITextView has to be set to true before doing changes on the Font/Color and then if you'd like set it back to false after doing these changes. This also was reproducible on an ObjC app.

Also another thing to take into account is that if your text is detected to be a phone number/address/etc. you want to change TintColor instead.

Please give this a try and if the problem persists please reopen the bug report and attach a test case showing the exact steps you took.
