[iOS] Crash in libobjc.A.dylib`objc_msgSend during AssetBundle download

iOS

-

Steps to reproduce:
1. Download & Open the project
2. Build the project to iOS using BuildInfoList.asset (found in Assets folder)
3. Throttle your iOS device's internet connection.
I used "Network Link Conditioner" from Xcode tools (and then shared the Ethernet connection to the phone via Wi-Fi) with these settings:
Downlink: Bandwidth - 2 Mbps, Packets dropped 0%, Delay 10ms
Uplink: Bandwidth - 1 Mbps, Packets dropped 0%, Delay 10ms
4. Deploy the game to iOS device
5. Select "Dev QA" in the initial scene
6. After the game loads, follow the instructions onscreen (go through the tutorial)

The game constantly downloads data from the background, at some point (usually ~1 minute into tutorial) it crashes.

Result: Crash in libobjc.A.dylib`objc_msgSend + 16

Reproduced on: 5.6.3f1

Fixed in 5.6/2017.1/2/3 and 2018
