Hey, I have a problem in Multithreading.<br />
To describe this, I have two threads.<br />
On main thread I have some logic<br />
And on another thread, I have a logic and some logic to UI which will update UI.<br />
What I want to do is that I want to call some method after the UI on another thread is updated.<br />
I think I am supposed to use NSOperationQueue or something. or background queue.<br />
but I have read the concurrency programming and threading guide and I still have no idea how to do it.<br />
<br />
So how to do it so that I can call a method after a thread is finished?<br />
thanks!

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

Swift is a compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program. A second free implementation of Swift targets Microsoft's Common Language Infrastructure (a.k.a. .NET) and the Java/Android platform.
