Hi,

is you set “Behaviour In background” to “Exit” in Build Player Setting? May it will force close you app during app goes to Background mode (as you said crash at time of after screen goes to sleep mode)

I also advice to take copy and try that copy with latest version of Unity v5.5.1p4.

Looks like this is fixed in 5.5.1p3 and is slated for wide release in 5.6.0 currently targeting March 2017

Update 3/2/2017 - It looks like this fix has been published in release 5.5.2, not sure why the issue tracker says that it’s fixed in 5.6.0 rather than 5.5.2 though …

I changed my build setting in Xcode from IOS 8 to IOS 9. That did it for me. still don’t know why tho.
