[fahd9567]

in this page i have7 issues
1- Cannot convert value of type 'SessionSettings.Type' to expected argument type 'SessionSettings'
2- Value of type 'ARViewContainer' has no member 'placementSettings'
3- Value of type 'ARViewContainer' has no member 'placementSettings'
4-Type of expression is ambiguous without more context
5- Type of expression is ambiguous without more context
6 and 7 - 'nil' requires a contextual type
