AutoLayout helper methods

[mdb1]

👋 Intro

Add a couple of lightweight classes with helper methods for programmatic AutoLayout

🤔 What changed?

• Added convenience methods to add constrained views
• Added convenience methods to pin views using constraints
• Moved Spacing out of Constants to an enum
• Use the new methods for everything UI related in the project
• Added unit tests

Example

Before

stackView.translatesAutoresizingMaskIntoConstraints = false
addSubview(stackView)
NSLayoutConstraint.activate([
    stackView.topAnchor.constraint(equalTo: topAnchor),
    stackView.leadingAnchor.constraint(equalTo: leadingAnchor),
    stackView.trailingAnchor.constraint(equalTo: trailingAnchor),
    stackView.bottomAnchor.constraint(equalTo: bottomAnchor)
])

After

addSubview(stackView, insets: .none)

Using different spacings / relationships

addSubview(
    hexaLabel,
    constrainedBy: [
        .top: .medium,
        .bottom: .medium,
        .trailing: .medium
    ]
)
hexaLabel.pin(
    .leading,
    to: .trailing,
    of: nameLabel,
    relatedBy: .greaterThanOrEqual,
    constant: Spacing.large.rawValue
)
