Jump to UICollectionViewController and report cocould not load NIB in bundle solution. uicollectionview

The error code is as follows: 'Could not load NIB in bundle: 'nsundle </Users/mac/Library/Developer/CoreSimulator/Devices/A0182119-C6AC-4732-BF37-3E6D35B102E1/data/Containers/Bundle/Application/E5F586ED-526F-4D52-9C7C-9335E772F666/00-ItcastLottery.app> (loaded) 'with name 'product''

The custom cell of collectionViewController in the project is created by xib. However, this error is reported every time you run it, so that the xib file named "product" cannot be loaded. None of the methods found on the Internet can be used. The reason is not found until the second night of troubleshooting, but it is easy to ignore. If you do not know, you may fall behind here in the future.

Static NSString * const reuseIdentifier = @ "product"; this line is used to set the identifier code in the UICollectionViewController. m file. The problem lies in the "product" string. The identifier string must be the same as the name of the custom cell file loaded by the UICollectionViewController.

This note is not mentioned in the MJ course video. The self-taught children's shoes should be solved according to the above methods.
