How can you check a collision of two nodes without changing their position?

I'd like to test when one node touches another. For this I use the following code:



struct physicBodyCharacters {
static let cardNumber = 1
static let anotherCardNumber = 2
static let nobodyNumber = 0
}


First Node:



card = SKSpriteNode(texture: cardTexture)
card.position = CGPoint(x: gameScene2.size.width / 2 + 150, y: 95)
card.zPosition = 3
card.setScale(1)
card.physicsBody = SKPhysicsBody(texture: cardTexture, size: card.size)
card.physicsBody?.affectedByGravity = false
card.physicsBody?.categoryBitMask = UInt32(physicBodyCharacters.cardNumber)
card.physicsBody?.collisionBitMask = UInt32(physicBodyCharacters.nobodyNumber)
card.physicsBody?.contactTestBitMask = UInt32(physicBodyCharacters.anotherCardNumber)


Second Node:



anotherCard = SKSpriteNode(texture: anotherCardTexture)
anotherCard.position = CGPoint(x: 31 , y: 532)
anotherCard.zPosition = 2
anotherCard.setScale(1)
anotherCard.physicsBody = SKPhysicsBody(texture: anotherCardTexture, size: anotherCard.size)
anotherCard.physicsBody?.affectedByGravity = false
anotherCard.physicsBody?.categoryBitMask = UInt32(physicBodyCharacters.anotherCardNumber)
anotherCard.physicsBody?.collisionBitMask = UInt32(physicBodyCharacters.nobodyNumber)
anotherCard.physicsBody?.contactTestBitMask = UInt32(physicBodyCharacters.cardNumber)


didBegin Function:



func didBegin(_ contact: SKPhysicsContact) {
print("contact")
let contanctMask = contact.bodyA.categoryBitMask | contact.bodyB.categoryBitMask

switch contanctMask
{
case UInt32(physicBodyCharacters.cardNumber) | UInt32(physicBodyCharacters.anotherCardNumber):
print("hit")
default:
break
}
}


My goal is that "hit" will be output, but without changing the positions of card and anotherCard. They should touch each other, but not move.



Thank you in advance
