Detect assign instance function.
-
x = self.func
- Check function is
instance function
. - Check self is
struct
- Check function is
-
y(self.func)
- Check function is
instance function
. - Check parameter is
escaping closure
- Check function is
func escape(block: @escaping () -> Void) {}
class Temp {
func instanceFunction() {}
func leak() {
let x = self.instanceFunction
escape(block: self.instanceFunction)
}
}
Detect instance captured by blocks(closure/function).
