I need to implement following layout using IB

Alright, the culprit was following code, constraint and everything was set correctly, but when I update the constant of height constraint in viewWillLayoutSubviews, although the constant value gets updated, collection view scrolling stops working. And here I was searching the issue in IB thinking it is a constraint issue.
I know that
(Int) -> Void can't be typecasted to
(Any) -> Void:

It's all about variance and Swift closures.
Swift is covariant in respect to closure return type, and contra-variant in respect to its arguments. This makes closures having the same return type or a more specific one, and same arguments or less specific, to be compatible.
(Arg1) -> Res1 can be assigned to
(Arg2) -> Res2 if
Res1: Res2 and
To express this, let's tweak a little bit the first closure:
I have been working with sorting algorithm and I found out that quicksort doesn't work correctly with swap function without a temporary variable. I have attached the code below. You can execute this code in swift playground, its written in swift. This is the link to execute this code online. Please let me know any other info you require to sort this out. I would really appreciate if somebody can explain this.
Note - I have commented the two kinda code in swap functions. one without temporary variable and other is a temporary variable. This code perfectly works with swap function with a temporary variable....

Your "swap without temporary variable" does not work if both arguments point to the same array element:
I am stuck in a very weird situation.When i create an IPA and install it in to any device, its crashing at one fixed point.But when i install directly from xcode to device, it works perfectly fine and no crashes.Tried almost every possible solution available, deleting the build folder, cleaning, removing files and adding them again etc.. Below is the crash log for refernce. Any help would be appreciated THanks...

if everythink is perfect then edit your scheme from debug to release mode.
I would like to remove duplicates of lines in a string with Swift 3. I got to do it but unfortunately at the end of the process the lines lost the order. Here is my code:...

Tweaking @LeoDabus' comment…
When defining a class in Swift, you can have
var properties which are like normal fields in other OOP languages, but also
let properties which are both read-only and immutable (like
T const * const in C++).
However is there a Swift equivalent of C++'s
T * const? (That is, the field itself is immutable, but the object it points to is mutable)?
Here's a representation of my scenario:...

By default, protocol typed objects have value value semantics. As a consequence, they're not mutable if the variable is a
To introduce reference semantics (and by extension, the mutability of objects referred to be a
let constant), you need to make your protocol into a class protocol:

Follow this script to install the libzmq on your machine.
Build the project.
Currently, in order to run swift kernel locally, you need to create a file named kernel.json. Put the following content to the file and replace the Path/to/iSwift with your local clone path.
Install Jupyter kernel: (replace the Folder/that/has/kernel/json with the path of the folder that contains the kernel.json file)
Run Jupyter Notebook (token needs to be empty):
Install Swift 3.0.
Check if you have libzmq installed.
Continue from step 2 in the section above.
Simply clone this repo and run docker build -t iswift .. It will build the docker image.
