Tutorials - Using Navigation View does not work in iOS simulator or iPhone
Got Tutorials - Using Navigation View to work on Mac with Safari browser.
When run on iOS Simulator "crashes" (no error messages) when enter any number on first screen
When run on iPhone gets to third screen ("Step 3") but display is wrong -- looks like:
Step 3 (just text no back arrow)
Step 2 (just text no back arrow)
Choose an operation
Keyboard is diplayed here -- when press "Done" Keyboard disappears
But, nothing happens when touch the Calculate! (just stays on same screen)
Also, how should I try to debug this kind of scenario in the future (works in browser, does not on device)?
