closure property declaration

SomeView.swift

class SomeView {
    
    // Declare property as a closure that's lazily executed on evaluation
    let label: UILabel = {
        // Create view within closure
        let view = UILabel()
        
        // Do whatever kind of configuration you want on it
        view.font = .systemFont(ofSize: 14)
        view.textColor = .blue
        
        // return the view at the end of the closure
        return view
    }() // <-- these parenthesis are important! If you don't include them, you'll get an "accurate" but cryptic compiler error
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // You can access the property by name without performing any sort of special initialization or anything
        addSubview(label)
        /* blah blah do auto layout */
        label.text = "This all should work"
