Getting 64bit architecture error for Private Api

[AnkitPanchal10]

I need to toggle AirPlane mode programmatically using the Private API RadiosPreferences, but I am getting a compile error that RadioPreferences does not support 64-bit architecture arm64.
I have import below header file in my project.

#import <Foundation/Foundation.h>

@protocol RadiosPreferencesDelegate
-(void)airplaneModeChanged;
@end


@interface RadiosPreferences : NSObject {
    
    struct __SCPreferences *_prefs;
    int _applySkipCount;
    id <RadiosPreferencesDelegate> _delegate;
    BOOL _isCachedAirplaneModeValid;
    BOOL _cachedAirplaneMode;
    BOOL notifyForExternalChangeOnly;
}

- (id)init;
- (void)dealloc;
@property(nonatomic) BOOL airplaneMode;
- (void)refresh;
- (void)initializeSCPrefs:(id)arg1;
- (void)notifyTarget:(unsigned int)arg1;
- (void)synchronize;
- (void *)getValueForKey:(id)arg1;
- (void)setValue:(void *)arg1 forKey:(id)arg2;
@property(nonatomic) BOOL notifyForExternalChangeOnly; // @synthesize notifyForExternalChangeOnly;
@property(nonatomic) id <RadiosPreferencesDelegate> delegate; // @synthesize delegate=_delegate;

@end

Here is the Xcode compile error.
Can you please update the header file or give a proper solution to use this.

Thanks in advance.

Undefined symbols for architecture arm64:

I think you don't need to compile this code, it's already there.
Try this https://github.com/nst/iOS-Runtime-Headers#sample-usage for your purpose without adding anything.
