Dependencies: If application uses third party libraries or cocoa pods, then those libraries or pods are needed to be install for test as well. Test class (Test Suit) extends XCTestCase. Get brushed up before starting: All test classes have two methods in common setUp & tearDown. ...

Integrated PDF signatures are explained quite graphically and in more detail in the Adobe document Digital Signatures in a PDF. They furthermore are specified in the PDF specification ISO 32000-1:2008 made available here by Adobe in section 12.8 Digital Signatures. Depending on your programming c...

ParameterDescriptionDecodePixelWidthWill load the BitmapImage with the specified width. Helps with memory usage and speed when loading large images that are meant to be displayed smaller on the screen.

What is Template Haskell? Template Haskell refers to the template meta-programming facilities built into GHC Haskell. The paper describing the original implementation can be found here. What are stages? (Or, what is the stage restriction?) Stages refer to when code is executed. Normally, co...

Fresco is a powerful system for displaying images in Android applications. In Android 4.x and lower, Fresco puts images in a special region of Android memory (called ashmem). This lets your application run faster - and suffer the dreaded OutOfMemoryError much less often. Fresco also supports strea...

Practical examples of using Roslyn for source code transformations. Roslyn syntax trees are immutable. By calling a method like ReplaceNodes we generate a new node rather than modifying the existing one. This requires you to always change the object you have been working on.

This section provides an overview of what responsive-design is, and why a developer might want to use it.
