Hey Batigol,
If you could, would you be able to test this issue on the 4.6.1 version of UE4 to see if this issue is still occurring for you? I have been able to launch on and package and deploy from a Mac to an iOS device via the 4.6.1 build. There have been many mobile fixes implemented since 4.4.3. It may be possible that this issue has been resolved in a newer build.
If the issue has not been resolved, please be sure to provide an updated build log so that I may be able to compare them to the previous log that you have provided.
Thanks and have a great day!
