Swift5.7的正确语法(转义闭包捕获非转义参数“块”)

Question

在"let runBlock = SCNAction.run {(节点) -> Void块(节点) }“行中得到”转义闭包捕获非转义参数‘块’错误“，这似乎是由旧语法引起的，不知道这里的正确用法是什么。

extension SCNAction {

class func waitForDurationThenRemoveFromParent(duration:TimeInterval) -> SCNAction {
    let wait = SCNAction.wait(duration: duration)
    let remove = SCNAction.removeFromParentNode()
    return SCNAction.sequence([wait,remove])
}

class func waitForDurationThenRunBlock(duration:TimeInterval, block: ((SCNNode?) -> Void) ) -> SCNAction {
    let wait = SCNAction.wait(duration: duration)
    let runBlock = SCNAction.run { (node) -> Void in
        block(node)
    }
    return SCNAction.sequence([wait,runBlock])
}

class func rotateByXForever(x:CGFloat, y:CGFloat, z:CGFloat, duration:TimeInterval) -> SCNAction {
    let rotate = SCNAction.rotateBy(x: x, y: y, z: z, duration: duration)
    return SCNAction.repeatForever(rotate)
}

}

让这个块逃跑

class func waitForDurationThenRunBlock(duration:TimeInterval,  block: @escaping((SCNNode?) -> Void) ) -> SCNAction {
    let wait = SCNAction.wait(duration: duration)
    let runBlock = SCNAction.run { (node) -> Void in
        block(node)
    }
    return SCNAction.sequence([wait,runBlock])
}
