Things to commit just before leaving your job
// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

Combine multiple .a static libraries, which may each have multiple architectures, into a single static library
#!/bin/sh
# Combined all static libaries in the current directory into a single static library
# It is hardcoded to use the i386, armv7, and armv7s architectures; this can easily be changed via the 'archs' variable at the top
# The script takes a single argument, which is the name of the final, combined library to be created.
#
# For example:
# => combine_static_libraries.sh combined-library
#
# Script by Evan Schoenberg, Regular Rate and Rhythm Software
// Props to the fine folks on this thread http://bbs.iosre.com/forum.php?mod=viewthread&tid=694

// Example output of a call to dailyUsageStasticsForBundleIdentifier or weeklyUsageStasticsForBundleIdentifier
// Inline comments are educated guesses at meaning
// {
// Airdrop = 0; // Has App used Airdrop
// Airplay = 0; // Has App used Airplay
// BBCondition = 0; // ?? BB = Backboard? This number is a float (ie 24.8766038700895)
//
// // No idea what the below units are, or what BLD means

iOS 9 Enable Splitscreen Jailbreak Tweak (Theos)
/* How to Hook with Logos
Hooks are written with syntax similar to that of an Objective-C @implementation.
You don't need to #include <substrate.h>, it will be done automatically, as will
the generation of a class list and an automatic constructor.
%hook ClassName
// Hooking a class method

Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)
# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions
# (A similar approach works for older versions too, just change the version number after DeviceSupport)
