A Boolean value that indicates whether the guide is focusable.
- iOS 9.1+
- tvOS 9.0+
If the value of this property is
true (the default), then the guide may be focusable. Some conditions, defined by the system, may prevent the guide from being focusable even if it is enabled, such as when the guide’s frame overlaps with the currently focused view. However, if this property is set to
false, then the guide isn't focusable.
