You should have mentioned the solutions you tried and it did not work for you.

By the way, there are few steps that you can follow:

Step 1. Create your document type in info.plist

  • Give the name of your file type such as xyz
  • Define the type identifier such as com.app.xyz
  • Define the file icon against the key CFBundleTypeIconFiles

enter image description here

Step 2: Define the exported type identifier in info.plist

  • Add the same identifier that we added while defining document type, i.e. com.app.xyz

  • define your extension xyz, XYZ

enter image description here

Step 3: Now while initialising UIDocumentPickerViewController, use the UTtype with identifier you declared in first two steps:

let xyzUTType = UTType("com.app.xyz")
let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: [xyzUTType], asCopy: true)
