I have realised that the keyboard which appears on my application doesn't have the same layout/appearance than others on the same device.
Keyboard that appears on my app:
Keyboard that appears on Safari:
Both screenshots has been taken on the same device with iOS 10.2. The second keyboard has like a modern style with more keys but using less space on the screen.
I think it could be related to some configuration on the project. I have tried the same textview but on a new empty project and I'm getting the new keyboard layout.
This is the current textview configuration (yes, it's an old project that uses xib files)
Do you know what I need to get the new keyboard style on my app?
