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 Gzip // using https://github.com/1024jp/GzipSwift

public struct GZIPEncoding: ParameterEncoding {
    
    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        
        var request = try urlRequest.asURLRequest()
        
        guard let parameters = parameters else { return request }

127.0.0.1、localhost、0.0.0.0、本机IP地址

localhost

首先，localhost 就是一个域名，域名指向 127.0.0.1，两者是一样的，如果是 mac，可以在 /etc/hosts 文件中看到这一行。

127.0.0.1     localhost

// Swift enums cannot be declared with a rawValue if they have associated values
// like good ol' Amargasaurus has. Using String(describing: dino) on a case with
// associated also includes the values, but works fine on unassociated cases.
// Mirror(reflecting: dino) can extract the name of an associated case, but is
// nil for unassociated cases. Our hero ?? swoops in to save the day!

enum Sauropoda {
    case Amargasaurus(things: Int64, hasOtherThing: Bool?)

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
