Chartboost is causing a runtime error for me on iOS 9 devices. It works fine on iOS 14 and iOS 12, but consistently gives the following error on iOS 9:
NSInvalidArgumentException: - [_NCSFLocale usesMetricSystem]: unrecognized selector sent to instance 0x165a0b00
The error message goes on and on but does mention Chartboost specifically:
_ZN16ChartboostPlugin4initEP9lua_Stat + 2410
Fortunately, you can include the plugin without causing iOS 9 devices to crash. The problem doesn’t occur until Charboost is initialized, so you can still use Chartboost on iOS builds if you do something like put Chartboost inside an if-then statement along the lines of:
if ( system.getInfo( "targetAppStore" ) == "apple" and tonumber( string.sub( system.getInfo( "platformVersion" ), 1, 1 ) ~= 9 ) then
-- All your Chartboost stuff here
I don’t know if the root problem is worth fixing/can be fixed, but I bring this up for folks who use Chartboost and aren’t in the habit of testing on iOS 9 devices.
