A list of methods and properties conforming to `UIAppearance` as of iOS 12 Beta 3

Generate the list yourself:

$ grep UI_APPEARANCE_SELECTOR ./*     | \

Detect a tap on a URL inside a UITextView. Note: the rs_links method isn't included -- you'll need something that takes text and returns an array of detected links. This gist just demonstrates walking through the UITextView characters.
@implementation UITextView (RSExtras)
static BOOL stringCharacterIsAllowedAsPartOfLink(NSString *s) {
/*[s length] is assumed to be 0 or 1. s may be nil.
Totally not a strict check.*/
if (s == nil || [s length] < 1)
return NO;

A simple way to detect at runtime if we're running in UIKit legacy mode or the new "flat" variant. Written for our PDF iOS SDK (http://pspdfkit.com), where the precompiled binary needs to detect at runtime in what variant it's running. Want more stuff like that? Follow me on Twitter: http://twitter.com/steipete
// Taken from http://PSPDFKit.com. This snippet is under public domain.
#define UIKitVersionNumber_iOS_7_0 0xB57
BOOL PSPDFIsUIKitFlatMode(void) {
static BOOL isUIKitFlatMode = NO;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
// We get the modern UIKit if system is running >= iOS 7 and we were linked with >= SDK 7.
if (kCFCoreFoundationVersionNumber >= kCFCoreFoundationVersionNumber_iOS_7_0) {
isUIKitFlatMode = (NSVersionOfLinkTimeLibrary("UIKit") >> 16) >= UIKitVersionNumber_iOS_7_0;
}

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

App Store Review Guidelines
Introduction
Apps are changing the world, enriching people’s lives, and enabling developers like you to innovate like never before. As a result, the App Store has grown into an exciting and vibrant ecosystem for millions of developers and more than a billion users. Whether you are a first time developer or a large team of experienced programmers, we are excited that you are creating apps for the App Store and want to help you understand our guidelines so you can be confident your app will get through the review process quickly.
The guiding principle of the App Store is simple - we want to provide a safe experience for users to get apps and a great opportunity for all developers to be successful. We do this by offering a highly curated App Store where every app is reviewed by experts and an editorial team helps users discover new apps every day.

Lots of books, here's a way to enjoy them! Just my suggestion, I found this to be a great way to get into the overall Cosmere.

Cosmere

  1. Mistborn Era 1
    1. The Final Empire
    2. The Well of Ascension
    3. The Hero of Ages
  2. Elantris (This is one of his first books, it has a noticabley different style, but the story is fun and has some Cosmere stuff for later)
  3. The Emporer's Soul: Elantris Novella
  4. Stormlight Archive #1 : The Way of Kings

Execute lldb command and open its output in Kaleidoscope diff

Diff output of two lldb commands

Setup

  1. Copy the contents of the last snippet (lldbinit) from the gist page, and paste into your .lldbinit file. This makes the ksdiff macro known inside lldb.
  2. Put file ksdiff.py in ~/.lldb/
  3. sudo pip install temp
  4. Restart Xcode debug session

Example

(lldb) ksdiff ;
