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

import Foundation
import NIO
import NIOHTTP1

// Inspired/parts copied from http://www.alwaysrightinstitute.com/microexpress-nio/

final class HelloHandler: ChannelInboundHandler {
    typealias InboundIn = HTTPServerRequestPart
    
    func channelRead(ctx: ChannelHandlerContext, data: NIOAny) {

chriseidhof

import Foundation

struct Handler {
    let handleJSON: (Data) throws -> Void
    
    init<T: Decodable>(handler: @escaping (T) -> Void) {
        handleJSON = { data in
            let object = try JSONDecoder().decode(T.self, from: data)
            handler(object)
        }
