check 1st arg of UINib#nibWithNibName

Did match nib name to xib file name?

+ (instancetype)create {
  UINib *nib = [UINib nibWithNibName:@"DID_NIB_NAME_MATCHE_TO_XIB_FILE_NAME?" bundle:nil]; // <<<<
  TenKeyViewController *view = [nib instantiateWithOwner:self options:nil][0];
  return view;
}

check xib file has trash reference

  • open xib file you're editing
  • click 'View'
  • If exist grayed item (transmitted item)
    • re-create xib because 'trash reference' is rest in the xib file
