my custom framework crashing 'Could not load NIB in bundle

问题

I have a custom framework which includes one xib and a UIView class for the same.

when I connect my test app with the framework, it got crashed

 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </private/var/containers/Bundle/Application/10A66571-E4BA-4C82-BDCE-82DA8018CA1C/cam.app> (loaded)' with name 'scanner''

libc++abi.dylib: terminating with uncaught exception of type NSException

my framework code

import UIKit
import QKMRZScanner
public class scanner: UIView,QKMRZScannerViewDelegate {

    @IBOutlet var mrzScannerView: QKMRZScannerView!

    public func mrzScannerView(_ mrzScannerView: QKMRZScannerView, didFind scanResult: QKMRZScanResult) {
        print(scanResult.documentType)
    }

    override  init(frame: CGRect) {
        super.init(frame: frame)
        commitinit()
        mrzScannerView.delegate = self
    }


    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    private func commitinit(){
        Bundle.main.loadNibNamed("scanner", owner: self, options: nil)
        addSubview(mrzScannerView)
        mrzScannerView.frame = self.bounds
        mrzScannerView.autoresizingMask = [.flexibleHeight, .flexibleWidth]
    }

    public func capture(){
        mrzScannerView.startScanning()
    }


}

my test app code below

import UIKit

import testfrme
class ViewController: UIViewController {

    @IBOutlet weak var tt: scanner!
    override func viewDidLoad() {
        super.viewDidLoad()
        let d = scanner()
        d.capture()

    }


}

can anyone help me to understand why its crashing ?? full source code of both available here testapp code framework code

new crash screenshot

UPDATED :

When i tried

        mrzScannerView = Bundle(for: QKMRZScannerView.self).loadNibNamed("QKMRZScannerView", owner: self, options: nil)

am getting below error !enter image description here]3

My xib connections look like this

回答1:

Make sure, that your scanner views Nib is exactly called "scanner".
Don't set your nibs TopView to type "scanner". Instead set filesOwner to "scanner".
Add a subview to your nib, set this views class to "QKMRZScannerView".
Connect this view to your @IBOutlet var mrzScannerView

Load your views nib like this:

func commitinit() {  
    let nib = UINib(nibName: String(describing: self), bundle: Bundle(for: type(of: self))) 

    guard let view = nib.instantiate(withOwner: self, options: nil).first as? UIView else {
        fatalError("Failed to instantiate nib \(nib)")
    }
    self.addSubview(view)
    view.frame = self.bounds
    view.autoresizingMask = [.flexibleHeight, .flexibleWidth]
}

回答2:

in your commitinit func add these codes

let bundle = Bundle(identifier:"your Bundle ID") 
bundle?.loadNibNamed("your XIB file name", owner: self,options: nil)
