iOSTextField Xojo v2019r3.1 Simulator problem


With Xojo 2019r3.1 all iOSTextField render with a white text on white background … not usable.
This problem appears for both the initial text and when typing.

AFAIK it concerns the Simulator only, running on physical device seems correct.
iOSTextArea seems ok.

Easy to reproduce:

From Xojo IDE, new project, select Examples/iOS/Apps/XojoNotes
Just changed the DetailView / Title label to reflect the Xojo version

With 2019r2.1:

With 2019r3.1:

Config tested:
iMacPro - macOS 10.15.14 (Catalina)
Xcode/Simulator 11.4.1
MacBook Pro - macOS 10.14.6 (Mojave)
Xcode/Simulator 11.2

With the Apple requirements to use Xojo 2019r3.1 as from June, it’s more than annoying.
It’s hard to test apps on physical devices only.

I hope some people can reproduce and confirm this ??

Tanks !

I don’t see that behavior on my setup of:

  • macOS 10.14.6
  • Xcode/Simulator 11.2.1
  • iOS 13.2

Hi Paul,

Would you mind trying with other iOS versions ?

I confirm it’s working with 13.4
Not with 10.3, 11.3, 12.0, 12.1, 12.2 or 12.4


On iOS.System.Version < 13 you get this behavior. Workaround is to assign a ColorGroup to the TextField TextColor:


And it looks like this case is fixed in the 2020r1 test builds, so if you’re a tester be sure to give it a try.

Thanks, I’ll give it a try.

I confirm this seems to be fixed in 2020r1 test build 49128.

So when 2020r1 comes out with the fix, will the assigned ColorGroup be a problem? Curious if I need to remove those. Speaking of which, it’s not obvious in the IDE how to remove a ColorGroup (assign a color?).

Curious on this too. In my last update last month or so, I had the problem of some “invisible “ text fields. Assigning the color group fixed this nicely, but what happens in 2020r1? Unassigned them and go back to the pre 19r3 way, or will they both work and no need to revert back?
