    Hello everyone,

    i have issue, i've tested my app on iPad & iPhone on real devices all works fine without crashes, but when i trying to run it in simulator i've got errors (App Store Testers also have crash on launch on iPad 13.3.1, i think that they check all apps in simulators):

    Code (csharp):

    Thanks for answer.
    But if i make build with "Target Simulator SDK"(Unity), it should be launched on real device? it will throw error?
    Or i have to make xcode build with "Target Device SDK" anyway? (here is no crashes, but when AppStore checking app they have crashes :confused:)

    Did you ever get this sorted out? My app got rejected from the store and it looks like this is why. Works fine on real devices, but I guess they test in a simulator
