Description

Steps to Reproduce

  1. Access DeviceDisplay.MainDisplayInfo on iOS 10.2

Expected Behavior

Display info is returned.

Actual Behavior

App crashes.

Basic Information

  • Version with issue: 1.6.1
  • Last known good version: 1.5.3.2
  • IDE:
  • Platform Target Frameworks:
    • iOS: 10.2
  • Affected Devices: iPhone/iPad with iOS 10.2 or lower

The feature merged with #1443 accesses property maximumFramesPerSecond which was added with iOS 10.3 but is not supported/known on earlier iOS versions. Thus the app crashes with the following error:
