I am running into a similar issues, which strangely enough only happens on physical devices and not the simulator. @apsakash were you ever able to find a solution?

I am running into a similar problem - @alexiOSxCODE were you ever able to solve this?

I also just ran into this issue with using a bundle ID that began with "to" (the website for my product ends with a ".to" top level domain). I had to change the bundle ID to fix it. Is there any official reasoning or policy from Apple about why this is disallowed or for some other reason disables the keyboard being visible in settings?
