静态成员＆＃39; isSupported＆＃39;不能在类型＆＃39; ARConfiguration＆＃39;的实例上使用

Question

获得＆＃39;静态成员＆＃39; isSupported＆＃39;不能在类型＆＃39; ARConfiguration＆＃39;的实例上使用＆＃39;

import ARKit
    // Display Agumented button only if device supports it
    let session = ARSession()
    var sessionConfig: ARConfiguration = ARWorldTrackingConfiguration()
    if sessionConfig.isSupported {
        bottomBarView.leadingBarButtonItems = [ hButton, fButton, agumentedButton ] }
    else { bottomBarView.leadingBarButtonItems = [ hButton, fButton ] }

    bottomBarView.trailingBarButtonItems = [ aButton, bhButton, cButton ]
  }

我在这里做错了什么？

Answer 1

正如错误消息清楚地告诉您，您必须说

if ARWorldTrackingConfiguration.isSupported {
