I take no credit for this post, just happened to have it saved in a document and thought I'd be doing an injustice by not sharing this information once I saw the original post was missing! All credit goes to the original author, and without further ado...

Student Loan Default: A Guide

I’ve been wanting to write this for a long time, and seeing that person be in $500,000 of debt and no one really helping him on r/studentloans, I felt it was time to summarize everything I’ve learned. While there is great information on this sub, it is not centralized. It requires some digging. I hope now to bring all of it to the surface.

Build settings reference

Active Build Action (ACTION)

A string identifying the build system action being performed.

Additional SDKs (ADDITIONAL_SDKS)

The locations of any sparse SDKs that should be layered on top of the one specified by Base SDK (SDKROOT). If more than one SDK is listed, the first one has highest precedence. Every SDK specified in this setting should be a "sparse" SDK, for example, not an SDK for an entire macOS release.

Alternate Install Group (ALTERNATE_GROUP)

iOS Shared Cache Extraction

Having fallen off the iOS-exploration train due to completing my Masters and other commitments, I have finally climbed back aboard in pursuit of understanding the telephony stack.

Like most things in iOS that are used frequently, the vast majority of the frameworks and libraries used in the telephony stack reside in the DYLD shared cache located at /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7.

In this post I am going to explain how to go about extracting this cache file so that you can then work with each library individually.

Get The Cache

The first step in all of this is to copy the cache over to your local machine. I did this using a program called iExplorer, but you can just as easily do it over SSH. As a side note, you can connect to your iDevice using SSH over USB if you install a tool called iProxy.

Edit Feb 4 5:16 PM: Skip to the bottom if you just want the article

It has been brought to my attention that rehosting someone else's content without asking them — even if you link to the original content — is not exactly polite. I did not ask the author before I rehosted his article, and while I feel I should have known better than to that, it just didn't occurr to me. It's not exactly plagarism, but it's still wrong on some level. I have reached out to him now about hosting it here publically, and if he says it's alright, I'll put it back.

You can find the original article here, on his site, and on his Medium page.

#Simple Theos Setup Instructions

Add the following to ~/.bash_profile (create the file if it does not exist by typing touch ~/.bash_profile into terminal. The touch command simply creates a file if it does not exist):

export THEOS=/opt/theos
export PATH=$THEOS/bin:$PATH
export THEOS_DEVICE_IP=your_idevice_ip THEOS_DEVICE_PORT=22

Using private Objective-C classes from Swift

In Objective-C, if you want to make use of one of Apple's internal classes, all you have to do is declare the class's interface with the methods you want to use. From there you can create instances of the class by using the NSClassFromString function to obtain a reference to the class object, like so:

[[NSClassFromString(@"_NSSomeClass") alloc] initWithFoo:5]

In Swift, this is not so easy. Referencing the type of the "hollow" Objective-C class interface anywhere in Swift code makes the compiler query the class for type information that is not known at compile time. This presents a huge problem. You cannot dynamically initialize a type either. Though, it seems the following code used to work at one point:

    'use strict';
    
    function copyMarkdown() {
        ...
        navigator.clipboard.writeText(markdown);
    }
    
    function addEventsToCopyElements() {
        // Get all elements with tag name clipboard-copy and class js-copy-branch
