I've updated all articles on Cocoa with Love and projects on Github to Swift 3. Summary of the changes here: https://www.cocoawithlove.com/blog/2016/09/14/updating-cocoawithlove.html …

Values and errors, part 2: comparing a basic error handling example in Swift and 7 other languages. https://www.cocoawithlove.com/blog/2016/08/23/result-types-part-two.html … #swiftlang

A look at `Result` types and their history of rejection from the #Swift standard library. https://www.cocoawithlove.com/blog/2016/08/21/result-types-part-one.html … #swiftlang

Oh, I see why none of my code broke after updating to Xcode 8b5... it was saving itself for Xcode 8b6.

1. MS Basic-80 2. Turbo Pascal 3. Hypertalk 4. IBM Linkway 5. LightspeedC 6. Think C++ 7. Perl 4 #FirstSevenLanguages

Updated to the latest Xcode beta and... nothing broke? Definitely need more test cases.

Updated Dispatch code in latest article for Xcode 8 beta 4. The beta 3 version lasted 18 hours before needing update https://www.cocoawithlove.com/blog/2016/07/30/timer-problems.html …

Thanks @slava_pestov for fixing "parameters may not have the 'var' specifier" oddity. That one was driving me crazy.

"Expression was too complex": looking at problems resolving function overloads in the #Swift compiler. https://www.cocoawithlove.com/blog/2016/07/12/type-checker-issues.html … #swiftlang

func ssort(_ a:[Int])->[Int]{return a.enumerated().min{$0.1<$1.1}.map{m in [m.1]+ssort(a.enumerated().filter{$0.0 != m.0}.map{$0.1})} ?? []}

Started "Learn to Code" iPad #Swiftlang Playground with my 4 y.o. – *loves* it. Prior exp. with Robot Turtles boardgame by @danshapiro helps

New personal rule: no more impulsive article updates after midnight.

I've retracted suggestion to use dispatch_semaphore_t. Rationale in section labelled "Update 2: Maybe not". Sorry for confusion.

Replacing pthread_mutex_t with dispatch_semaphore_t yields 30% speed improvement. Article & code updated, thanks @s_tolksdorf, @davedelong
