// Description:
// Creating Unique Accessibility Identifiers of every object at Runtime
//
// This is big for Native Automated Testing in conjunction with the XCTest Framework
// If you call this file the test recording software no longer has to grab the relative identifier because it
// can grab the absolute identifier making the test cases less difficult to write

// Use:
// In the viewDidLayoutSubviews() method in each ViewController put "self.setEachIDInViewController()"
// In the viewWillDisappear() method in each ViewController put "self.removeEachIDInViewController()"
// and this file will do the rest for you
//
// Tools:
// We make use of class extensions, mirroring, and the built in view hierarchy
//
// Note:
// If you see an issue anywhere please open a merge request and we will get to it as soon as possible.
// If you would like to make an improvement anywhere open a merge request.
// If you liked anything or are curious about anything reach out to one of us.
// We like trying to improve the iOS Community :)
// If you or your company decides to take it and implement it we would LOVE to know that please!!

/// UTF8View Elements Match Encoded C Strings
/// =========================================
///
/// Swift streamlines interoperation with C string APIs by letting you pass a
/// `String` instance to a function as an `Int8` or `UInt8` pointer. When you
/// call a C function using a `String`, Swift automatically creates a buffer
/// of UTF-8 code units and passes a pointer to that buffer. The code units
/// of that buffer match the code units in the string's `utf8` view.
///
/// The following example uses the C `strncmp` function to compare the
/// beginning of two Swift strings. The `strncmp` function takes two
/// `const char*` pointers and an integer specifying the number of characters
/// to compare. Because the strings are identical up to the 14th character,
/// comparing only those characters results in a return value of `0`.
///
/// let s1 = "They call me 'Bell'"
/// let s2 = "They call me 'Stacey'"
///
/// print(strncmp(s1, s2, 14))
/// // Prints "0"
/// print(String(s1.utf8.prefix(14)))
/// // Prints "They call me '"
///
/// Extending the compared character count to 15 includes the differing
/// characters, so a nonzero result is returned.
///
/// print(strncmp(s1, s2, 15))
/// // Prints "-17"
/// print(String(s1.utf8.prefix(15)))
/// // Prints "They call me 'B"

/**
A view that stacks its subviews along a single axis.
It is similar to UIStackView except that it uses StackLayout instead of Auto Layout, which means layout is much faster.
Although StackView is faster than UIStackView, it still does layout on the main thread.
If you want to get the full benefit of LayoutKit, use StackLayout directly.
Unlike UIStackView, if you position StackView with Auto Layout, you must call invalidateIntrinsicContentSize on that StackView
whenever any of its subviews' intrinsic content sizes change (e.g. changing the text of a UILabel that is positioned by the StackView).
Otherwise, Auto Layout won't recompute the layout of the StackView.
Subviews MUST implement sizeThatFits so StackView can allocate space correctly.
If a subview uses Auto Layout, then the subview may implement sizeThatFits by calling systemLayoutSizeFittingSize.

// MARK: - Subscripting a.k.a Resolving

// TL:DR;

/// var now: Date {
/// return resolve[\.now]
/// }
/// }
///

/// This subscript can be seen as an eqivalent to extend on a Coreader
/// This will be called when the Type D implements HasInstanceContext,
/// which will result in passing on the context.
/// Example usage:
///
/// extension HasInstanceAppContext {
///
/// /// Api itself implements HasInstanceAppContext
/// var api: Api {
/// return resolve[\.api]
/// }
/// }
///
