Previous worlds before update will not open to play with the new update 16.0 when the building terrain screen opens the game shuts down and the screen returns to the home screen with the app. New worlds generated will open to play but as you start to play the game quickly shuts down and goes to the home screen with the app on it.

Thank you for your report. This issue was, however, submitted earlier as MCPE-17695. Please perform a search next time to make sure your bug hasn't already been reported. The parent issue can easily be found by searching for "mcpe unresolved ios crash".
Could this be because there is not enough RAM? I also have this problem on my iPad 2. On the Windows 10 edition, worlds load without the game crashing.
