WatchOS app NavigationView/Title

I’m working on my apple watch extension and I have problem with navigation. I added navigationView and navigationTitle to the code like in the Dad Jokes app tutorial but the title is invisible. It is there for sure since it pushes my View a little bit down, but I can see only a a black background on the top, nothing else. It is the same with navigationLink, it navigates to the next View and if I tap the top left corner on my watch it navigates back, but the back arrow icon is also invisible somehow.
Anyone has idea what can be the problem?

Can you paste your code?

Paste your code in as text, rather than providing a screenshot.

To format the code nicely, place 3 back-ticks ``` on the line above your code and 3 back-ticks ``` on the line below your code. The 3 back-ticks must be the ONLY characters on the line. The back-tick character is located on the same keyboard key as the tilde character ~ (which is located below the Esc key on a US English keyboard). You can also highlight an entire code block and click the </> button on the toolbar to wrap the block for you.

This also makes it easier for anyone assisting as they can copy the code and carry out some testing.
