How to solve NSInternalInconsistencyException: reason: 'Invalid parameter not satisfying: (name != nil) && ([name length] > 0)'

Question

I get an NSInternalInconsistencyException when I use the OPPWAMobile payment library. I need to pass name somehow to OPPPaymentSchemeViewController so it passes it to initWithNibName. But I'm not sure how to do that in Xcode.

I've checked this stack overflow solution but it didn't help because I don't have direct access to the view controller.

I'm sure that the nib name is part of a property file somewhere but I'm not able to locate it.

Any ideas on how to do that?

Answer 1

I found the problem. I needed to mark OPPWAMobile.xcframework as "Embed & Sign" under Target->General->Frameworks, Libraries and Embedded Content.

I suspected that this may be the problem when I read the Apple documentation on how initWithNibName:bundle: behaves when nibName is nil.

If you specify nil for the nibName parameter and you do not override the loadView method, the view controller searches for a nib file as described in the nibName property.

Which means that I was getting an exception because the framework couldn't find the necessary nib file.

Answer 2

You have add OPPWAMobile-Resources.bundle on project.

Answer 3

In addition for adding the resource files and checking Embed & Sign in the general settings, Also make sure the order of the build phases are correct.

Answer 4

For anyone else coming here later... this can also be caused if you call super.init in a custom initialiser of a UIViewController and enter "" as the nibName:

❌

    init(foo: Foo) {
    self.foo = foo
    super.init(nibName: "", bundle: nil)
}

Instead, set the nibName to nil:

✅

    init(foo: Foo) {
    self.foo = foo
    super.init(nibName: nil, bundle: nil)
}
