The attached lldb command pblock command lets you peek inside an Objective-C block. It tries to tell you where to find the source code for the block, and the values captured by the block when it was created.

Consider this example program:

#import <Foundation/Foundation.h>

@interface Foo: NSObject
@end

@implementation Foo

	private let linkDetector = try! NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)

	struct LinkColoredText: View {
	enum Component {
	case text(String)
	case link(String, URL)
	}
