Pattern Matching in Swift Pattern Matching is one of the flagships of the Functional Programming paradigm, and Swift has you covered....

Strings + Integers This demo shows one way of implementing a mix of types in a Set. Code Sample enum StringOrInt: Hashable, CustomStringConvertible { case string(String) case int(Int) var description: String { switch self { case .int(let int): return String(int) case .string(let string): return string } } } var mixedSet: Set<StringOrInt> = Set([.string("@lintuxt"), .int(0), .string("@lintuxt"), .int(1)]) print(mixedSet) /* Output: [0, 1, @lintuxt] */

Code Sample import SwiftUI struct ContentView: View { @State private var checkAmount = 0.0 @State private var peopleQuantityIndex = 0 @State private var tipPercentage = 18 @FocusState private var shouldShowKeyboard: Bool static let currencyCode = Locale....

SwiftUI Cheatsheet A friendly way to remember some SwiftUI snippets. SwiftUI Children Limits SwiftUI by default limits its children to 10. However, this doesn’t mean that we can’t have more than ten elements in the same view. We just need to add the Group {...} directive.
