CGRect.maxX — gameArea.maxX
0
I am trying to keep the object in the screen/gameArea and i simply can't.
I use these if statement and it prevents the object from moveing to the right side
if player.position.x > gameArea.maxX - player.size.width/2 {
player.position.x = gameArea.maxX - player.size.width/2
}
but i can't apply to the other side because it crashes
if player.position.x < gameArea.maxX - player.size.width/2 {
player.position.x = gameArea.maxX - player.size.width/2
}

What is the error message from the crash? That should provide some useful information, or at least indicate what line the crash is on.

Your second example usesgameArea.maxXas well, when it probably should usegameArea.minX. This shouldn't necessarily be the source of the crash, but if there was a floating point error then both of them might fire in the same loop.

if player.position.x > gameArea.maxX - player.size.width { player.position.x = gameArea.maxX - player.size.width } if player.position.x < gameArea.minX + player.size.width { player.position.x = gameArea.minX + player.size.width }
