Get image height from x point in swift

I'm making another Swift game. The floor is the desert. This floor is a physicsbody (sprite kit) based on it's image texture. I want to know the height of the floor based on a specific x point (by instance the middle of the screen). If i use floor.size.height it gets the height like it is a rectangle (in other words, the maximum height possible). I want to get this Y point to make the player move upon it with physicsbody.

can anyone help with it?

You have no need. Just because you are using the physics, it's simply stating the floor with isDynamic = false and players with isDynamic = true and the other parameters as for example:

enum CollisionTypes: UInt32 {
    case player1 = 1
    case player2 = 2
    case floor = 4
}

floor.physicsBody?.categoryBitMask = CollisionTypes.floor.rawValue
floor.physicsBody?.contactTestBitMask = CollisionTypes.player.rawValue
floor.physicsBody?.collisionBitMask = 0

player1.physicsBody?.categoryBitMask = CollisionTypes.player1.rawValue
player1.physicsBody?.contactTestBitMask = CollisionTypes.floor.rawValue
player1.physicsBody?.collisionBitMask = CollisionTypes.floor.rawValue

This is only a point to start so hope it helps you.
