我是第一次使用 Swift的步伐.然而,由于我无法使其工作,因此第一次即将成为最后一次： let boundingBox = createdShape.frame //=SKShapeNodestride(from: Int(boundingBox.minX), to: Int(boundingBox.maxX), by: 10) { 结
let boundingBox = createdShape.frame //=SKShapeNode
stride(from: Int(boundingBox.minX), to: Int(boundingBox.maxX), by: 10) {
结果是：
Cannot invoke ‘stride’ with an argument list of type ‘(from: Int, to: Int, by: Int, () -> ())’
我究竟做错了什么？
语法应该是：let boundingBox = createdShape.frame //=SKShapeNode
for x in stride(from: Int(boundingBox.minX), to: Int(boundingBox.maxX), by: 10) {
// TODO: Use x here.
}
