Hi, I've written a SpriteKit game but am finding it hard to know how to add inappropriate purchases functionality within this, I know you can add a spritekit game above a swiftUI but unsure if can add swiftUI to spritekit game so can add purchase code, all info from within SpriteKit seems to not function. Or even better as code I know and love, can you add purchase functionality from within SpriteKit. would love to hear from you, Ruth
