Hello,

I attended WWDC this year, and overall it was a fantastic experience. I would, however, like to give some feedback on one particular aspect of the conference.

Before I begin, I understand that it would be easy to brush off my feedback as coming from just some grumpy English guy, but I genuinely believe this is important feedback. Please do read until the end.

I would like to ask that the cheering, whooping, clapping and hollering by conference staff is toned down.

I'm a person that would describe myself as "slightly introverted". I cannot begin to describe how deeply uncomfortable it was to walk into the registration room on Sunday to multiple employees cheering and clapping at me, trying to give me high fives. I understand the want to make people excited, but this needs to have its limits. During the conference, I got cheered and high-fived pretty much the entire week for things like:

In the process of evaluating the suitability of SFSafariViewController (SFSVC) for use within the Twitter iOS client, I encountered a number of bugs with differing severities, all of which I filed as Radars in Apple's bug reporting tool. Here is my attempt to holistically document their impact on our ability to adopt SFSafariViewController as a replacement for our existing WebViews.

Highest Severity

The fundamental blocker is Radar

	Strings:

	_NSCFString - a CFStringRef or CFMutableStringRef. This is the most common type of string object currently.
	- May have 8 bit (ASCII) or 16 bit (UTF-16) backing store
	_NSCFConstantString - a compile time constant CFStringRef, like you'd get with @"foo"
	- May also be generated by dynamic string creation if matches a string in a pre-baked table of common strings called the StringROM
	NSBigMutableString - an NSString backed by a CFStorage (https://github.com/opensource-apple/CF/blob/master/CFStorage.h) for faster handling of very large strings
	NSCheapMutableString - a very limited NSMutableString that allows for zero-copy initialization. Used in NSFileManager for temporarily wrapping stack buffers.
