通过cocopods 集成没显示扫描线

[CNDEVE]

lazy var scanView: SGScanView = {
    let configure = SGScanViewConfigure()
    configure.isShowBorder = true
    configure.borderColor = .clear
    configure.cornerColor = .white
    configure.cornerWidth = 3
    configure.cornerLength = 15
    configure.isFromTop = true
    configure.scanline = "SGQRCode.bundle/scan_scanline_qq"
    configure.color = .clear
    let x = 0.0 // 明确指定为CGFloat
    let y = 0.0 // 明确指定为CGFloat
    let w = self.view.frame.size.width
    let h = self.view.frame.size.height
    let scanView = SGScanView(frame: CGRect(x: x, y: y, width: w, height: h), configure: configure)
    scanView?.startScanning()
    scanView?.scanFrame = CGRect(x: 0, y: 0, width: w, height: h)
    return scanView ?? SGScanView()
}()  通过cocopods 集成没显示扫描线 能看看初始化有什么问题吗
