(iOS): Invariant Violation: requireComponent: 'RCTGuidanceView' was not found in the UIManager

[bmainz]

Description

Hello,

I get the following error message when I try to open the view in the simulator in iOS. In android everything works properly.
I have created a native module that works for android and iOS. However, the UI component RCTGuidanceView does not work for iOS yet.

Invariant Violation: requireNativeComponent: "RCTGuidanceView" was not found in the UIManager.

I am trying to integrate a HereMaps view with the latest Here Maps SDK (3.15.2). In the pods file the minimum iOS platform version is set to 12.0.

This is my Manager class:

#import <React/RCTViewManager.h>
#import <React/RCTUIManager.h>
#import <React/RCTLog.h>
#import "RCTGuidanceView.h"

@interface RCTGuidanceViewManager : RCTViewManager
@end

@implementation RCTGuidanceViewManager

RCT_EXPORT_MODULE(RCTGuidanceView) // also tried to leave it empty

- (UIView *)view
{
  return [[RCTGuidanceView alloc] init];
}
RCT_EXPORT_VIEW_PROPERTY(lat, double);
// more properties and methods

This is my custom view:

// RCTGuidanceView.h
#import <MapKit/MapKit.h>
#import <NMAKit/NMAMapScheme.h>
#import "React/RCTView.h"
@import NMAKit;
@interface RCTGuidanceView : RCTView <NMANavigationManagerDelegate> // also tried UIView here
 @property double lat;
...

// RCTGuidanceView.m
#import "RCTGuidanceView.h"
@import NMAKit;

@implementation RCTGuidanceView
//...

The JS embedding the native component:

import { requireNativeComponent, ViewPropTypes } from 'react-native'
import PropTypes from 'prop-types'

const RCTGuidanceView = requireNativeComponent('RCTGuidanceView', {
  name: 'RCTGuidanceView',
  propTypes: {
    lat: PropTypes.number,
    //...
    ...ViewPropTypes,
  },
})

export default RCTGuidanceView

Seems like it was an Xcode problem. Moved the files to another folder, working now.
