🚀❤️ YOU WILL LOVE UIKIT MORE THAN EVER ❤️🚀
Nothing is impossible!
Build awesome responsive UIs even simpler than with SwiftUI cause you already know everything.
With. Live. Preview. iOS9+.
SWIFT.STREAM COMMUNITY IN DISCORD
Xcode 13.0+
Swift 5.2+
Good mood
With CocoaPods
Add the following line to your Podfile:
pod 'UIKit-Plus', '~> 1.28.0'In Xcode 11.4+ go to File -> Swift Packages -> Add Package Dependency and enter there URL of this repo
https://github.com/MihaelIsaev/UISwift
To support iOS lower than 13 you have to set -weak_framework SwiftUI in Other Linker Flags in Build Settings.
Without that your app gonna crash on iOS lower than 13 because it will try to load SwiftUI without luck.
To simplify life with UISwift you can download our template!
For that run the following commands in console
git clone https://github.com/MihaelIsaev/UISwift.git
cp -R UISwift/Templates ~/Library/Developer/Xcode/
rm -rf UISwiftAfter that you will be able to go to File -> New -> Project and choose UISwift app! 🚀
💡After project creation you have to install UISwift manually either with Swift Package Manager or with CocoaPods
Together with project template you will get the file template 👍
Declare all the constraints in advance before adding view to superview. Even by tags.
Button("Click me").width(300).centerInSuperview()Build everything declarative way. Any view. Any control. Even layers, gestures, colors, fonts, etc.
Text("Hello world").color(.red).alignment(.center).font(.sfProMedium, 15)Use @State for any property, react on any thing, map states to different types, etc.
@State var text = "Hello world"
Text($text)
@State var number = 5
Text($number.map { "\($0)" })
@State var bool = false
Text($bool.map { $0 ? "enabled" : "disabled" })Everything is pretty clear. Clean short code without magic.
Declare subviews like in SwiftUI
body {
View1()
View2()
View3()
// btw it is NOT limited to 10
}Declare views or its styles in extensions. Subclass views. Use all the power of OOP.
Diffable data-source (yes yes for iOS9+). Dynamic colors for light/dark mode. Stateable animations. Reactivity.
Built-in ImageLoader, no need in huge 3rd party libs. Just set URL to Image. Fully customizable and overridable.
Image(url: "")
Image(url: "", defaultImage: UIImage(named: "emptyImage")) // set default image to show it while loading
Image(url: "", loader: .defaultRelease) // release image before start loading
Image(url: "", loader: .defaultImmediate) // immediate replace image after loading
Image(url: "", loader: .defaultFade) // replace image with fade effect after loading
Image(url: "", loader: ImageLoader()) // subclass from `ImageLoader` and set you custom loader hereEasy device model and type detection and ability to set values based on that.
Button("Click me").width(400 !! iPhone6(300) !! .iPhone5(200))Localizable strings
Localization.default = .en // set any localization as default to use it with not covered languages
Localization.current = .en // override current locale
String(.en("Hello"), .fr("Bonjour"), .ru("Привет"))Custom trait collections.
Live preview provided by SwiftUI (available only since macOS Catalina).
The only problem we have is that since names of views are the same in
UISwiftandSwiftUIwe should use aliases likeUButtonforButtonorUViewforView, so everything withUprefix. It is only necessary if you want to use live previews, otherwise there is no need to importSwiftUI, so no name conflicts.
💡 You can create as many preview structs as you need
ViewController example
#if canImport(SwiftUI) && DEBUG
import SwiftUI
@available(iOS 13.0, *)
struct MyViewController_Preview: PreviewProvider, DeclarativePreview {
static var preview: Preview {
Preview {
MainViewController()
}
.colorScheme(.dark)
.device(.iPhoneX)
.language(.fr)
.rtl(true)
}
}
#endifView example
#if canImport(SwiftUI) && DEBUG
import SwiftUI
@available(iOS 13.0, *)
struct MyButton_Preview: PreviewProvider, DeclarativePreview {
static var preview: Preview {
Preview {
UButton(String(.en("Hello"), .fr("Bonjour"), .ru("Привет")))
.circle()
.background(.blackHole / .white)
.color(.white / .black)
.height(54)
.edgesToSuperview(h: 8)
.centerYInSuperview()
}
.colorScheme(.dark)
.layout(.fixed(width: 300, height: 64))
.language(.fr)
.rtl(true)
}
}
#endifIt is just convenient way to create multiple previews inside one struct
Limitations:
- only 10 previews inside group
rtlandlanguageproperties can be set only to group, not to previews directly
#if canImport(SwiftUI) && DEBUG
import SwiftUI
@available(iOS 13.0, *)
struct MyPreviewGroup_Preview: PreviewProvider, DeclarativePreviewGroup {
static var previewGroup: PreviewGroup {
PreviewGroup { // 1 to 10 previews inside
Preview {
MainViewController()
}
.colorScheme(.dark)
.device(.iPhoneX)
Preview {
MainViewController()
}
.colorScheme(.light)
.device(.iPhoneX)
Preview {
// in this group title will be shown in `fr` language
UButton(String(.en("Hello"), .fr("Bonjour"), .ru("Привет")))
.circle()
.background(.blackHole / .white)
.color(.white / .black)
.height(54)
.edgesToSuperview(h: 8)
.centerYInSuperview()
}
.colorScheme(.dark)
.layout(.fixed(width: 300, height: 64))
}
.language(.fr) // limited to group
.rtl(true) // limited to group
}
}

Really often we have to create some views with constraints related to each other 😃
The classic way is to create a variable with view somewhere outside, like this
let someView = UView()then we used it with other views to make relative constraints
UView {
someView.size(200).background(.red).centerInSuperview()
UView().size(100).background(.cyan).centerXInSuperview().top(to: someView)
UView().size(100).background(.purple).centerXInSuperview().bottom(to: someView)
UView().size(100).background(.yellow).centerYInSuperview().right(to: someView)
UView().size(100).background(.green).centerYInSuperview().left(to: someView)
}But if it's not necessary to declare view outside the you can use tag! And easily rely to it from other views!
UView {
UView().size(200).background(.red).centerInSuperview().tag(7)
UView().size(100).background(.cyan).centerXInSuperview().top(to: 7)
UView().size(100).background(.purple).centerXInSuperview().bottom(to: 7)
UView().size(100).background(.yellow).centerYInSuperview().right(to: 7)
UView().size(100).background(.green).centerYInSuperview().left(to: 7)
}Even order doesn't matter 🤗
UView {
UView().size(100).background(.cyan).centerXInSuperview().top(to: 7)
UView().size(100).background(.purple).centerXInSuperview().bottom(to: 7)
UView().size(100).background(.yellow).centerYInSuperview().right(to: 7)
UView().size(100).background(.green).centerYInSuperview().left(to: 7)
UView().size(200).background(.red).centerInSuperview().tag(7)
}You even can add view later and all related views will immediately stick to it once it's added 🚀
let v = UView {
UView().size(100).background(.cyan).centerXInSuperview().top(to: 7)
UView().size(100).background(.purple).centerXInSuperview().bottom(to: 7)
UView().size(100).background(.yellow).centerYInSuperview().right(to: 7)
UView().size(100).background(.green).centerYInSuperview().left(to: 7)
}
DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
UIView.animate(withDuration: 1) {
v.body {
UView().size(200).background(.red).centerInSuperview().tag(7)
}
}
}Any constraint value may be set as CGFloat or with Relation and even Multiplier
// just equal to 10
View().leading(to: .trailing, of: anotherView, 10)
// greaterThanOrEqual to 10
View().leading(to: .trailing, of: anotherView, >=10)
// lessThanOrEqual to 10
View().leading(to: .trailing, of: anotherView, <=10)
// equal to 10 with 1.5 multiplier
View().leading(to: .trailing, of: anotherView, 10 ~ 1.5)
// equal to 10 with 1.5 multiplier and 999 priority
View().leading(to: .trailing, of: anotherView, 10 ~ 1.5 ! 999)
// equal to 10 with 1.5 multiplier and `.defaultLow` priority
View().leading(to: .trailing, of: anotherView, 10 ~ 1.5 ! .defaultLow)
// equal to 10 with 999 priority
View().leading(to: .trailing, of: anotherView, 10 ! 999)Ok, let's imagine that you have a view which is sticked to its superview
let view = View().edgesToSuperview()now your view have top, leading, trailing and bottom constraints to its superview and e.g. you want to change top constraint so you could do it like this
view.top = 16or
view.declarativeConstraints.top?.constant = 16the same way works with all view's constraints, so you can change them or even delete them just by setting them nil.
Another situation if you have a view which have a constrain to another relative view
let centerView = View().background(.black).size(100).centerInSuperview()
let secondView = View().background(.green).size(100).centerXInSuperview().top(to: .bottom, of: centerView, 16)and for example you want to reach bottom constraint of centerView related to secondView, do it like this
// short way
centerView.outer[.bottom, secondView] = 32 // changes their vertical spacing from 16 to 32
// long way
centerView.declarativeConstraints.outer[.bottom, secondView]?.constant = 32 // changes their vertical spacing from 16 to 32Root View Controller 🍀
View
alias is
UView
View may be created with empty initializer
View()or you can put subviews into it right while initialization
View {
View()
View()
}or you can wrap some view using inline keyword so that inner view will stick all edges to superview
View(inline: MKMapView())also you can add subviews to that superview by calling .body { ... } method. even multiple times.
View().body {
View()
View()
}.body {
View()
}.body {
View()
View()
View()
}VerificationCodeView
// implemented. to be described more
This is really bonus view! :D Almost every app now uses verification codes for login and now you can easily implement that code view with UISwift! :)
VerificationCodeField().digitWidth(64)
.digitsMargin(25)
.digitBorder(.bottom, 1, 0xC6CBD3)
.digitColor(0x171A1D)
.font(.sfProRegular, 32)
.entered(verify)
func verify(_ code: String) {
print("entered code: " + code)
}VisualEffectView
// implemented. to be described more
VisualEffectView(.darkBlur)
VisualEffectView(.lightBlur)
VisualEffectView(.extraLightBlur)
// iOS10+
VisualEffectView(.prominent)
VisualEffectView(.regular)
// iOS13+ (but can be used since iOS9+)
// automatic dynamic effect for light and dark modes
VisualEffectView(.darkBlur, .lightBlur) // effect will be switched automatically. darkBlur is for light mode.Create your own extension for your custom effects to use them easily like in example above
extension UIVisualEffect {
public static var darkBlur: UIVisualEffect { return UIBlurEffect(style: .dark) }
}WrapperView
It is simple View but with ability to initialize with inner view
WrapperView {
View().background(.red).shadow()
}.background(.green).shadow()and you could specify innerView`s padding right here
// to the same padding for all sides
WrapperView {
View()
}.padding(10)
// or to specific padding for each side
WrapperView {
View()
}.padding(top: 10, left: 5, right: 10, bottom: 5)
// or even like this
WrapperView {
View()
}.padding(top: 10, right: 10)LayerView

ImpactFeedback.bzz()Localization 🇮🇸🇩🇪🇯🇵🇲🇽
// set any localization as default
Localization.default = .en
// override current locale
Localization.current = .en
// create string relative to current language
let myString = String(
.en("Hello"),
.fr("Bonjour"),
.ru("Привет"),
.es("Hola"),
.zh_Hans("你好"),
.ja("こんにちは"))
print(myString)By default current language is equal to Locale.current but you can change it by setting Localizer.current = .en.
Also localizer have default language in case if user's language doesn't match any in your string, and you could set it just by calling Localizer.default = .en.
Also you can use localizable strings directly in Button, Text, TextView, TextField and AttributedString
Text(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
TextView(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
.placeholder(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
TextField(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
.placeholder(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
Button(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))
Button().title(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"), state: .highlighted)
AttrStr(.en("Hello"), .ru("Привет"), .fr("Bonjour"), .es("Hola"))Just create a dedicated localization file (e.g. Localization.swift) like this
extension String {
static func transferTo(_ wallet: String) -> String {
String(.en("Transfer to #\(wallet)"),
.ru("Перевод на #\(wallet)"),
.zh("转移到 #\(wallet)"),
.ja("＃\(wallet)に転送"),

.it("Copia il link negli appunti"),
.cs("Zkopírujte odkaz do schránky"),
.he("העתק קישור ללוח"),
.ar("نسخ الرابط إلى الحافظة"))
}
static var copyLinkSucceeded: String {
String(.en("Link has been copied to clipboard"),
.ru("Ссылка успешно скопирована в буфер обмена"),
.zh("链接已复制到剪贴板"),
.ja("リンクがクリップボードにコピーされました"),
.es("El enlace ha sido copiado al portapapeles"),
.fr("Le lien a été copié dans le presse-papiers"),
.sv("Länken har kopierats till Urklipp"),
.de("Der Link wurde in die Zwischenablage kopiert"),
.tr("Bağlantı panoya kopyalandı"),
.it("Il link è stato copiato negli appunti"),
.cs("Odkaz byl zkopírován do schránky"),
.he("הקישור הועתק ללוח"),
.ar("تم نسخ الرابط إلى الحافظة"))
}
static var shareNumber: String {
String(.en("Share number"),
.ru("Поделиться номером"),
.zh("分享号码"),
.ja("共有番号"),
.es("Compartir número"),
.fr("Numéro de partage"),
.sv("Aktienummer"),
.de("Teilenummer"),
.tr("Numarayı paylaş"),

Status bar style
In any ViewController you can set statusBarStyle and all its values are iOS9+.
override var statusBarStyle: StatusBarStyle { .default }
override var statusBarStyle: StatusBarStyle { .dark }
override var statusBarStyle: StatusBarStyle { .light }Colors
/// Simple color
UIColor.red
/// Automatic dynamic color: black for light mode, white for dark mode
UIColor.black / UIColor.white
/// color in hex, represented as int and supported by all color properties
0xFF0000
/// hex color converted to UIColor
0xFF0000.color
/// hex colors as dynamic UIColor
0x000.color / 0xfff.color
/// color with alpha
UIColor.white.alpha(0.5)
/// hex color with alpha
0xFFFFFF.color.alpha(0.5)Declare custom colors like this
import UIKit
import UISwift
extension UIColor {
static var mainBlack: UIColor { return .black }
static var otherGreen: UIColor { return 0x3D7227.color } // 61 114 39
}and then use them just like
Label("Hello world").color(.otherGreen).background(.mainBlack)Fonts
// implemented. to be described
/// helper to print all the fonts in console (debug only)
UIFont.printAll()Add your custom fonts to the project and then declare them like this
import UISwift
extension FontIdentifier {
public static var sfProBold = FontIdentifier("SFProDisplay-Bold")
public static var sfProRegular = FontIdentifier("SFProDisplay-Regular")
public static var sfProMedium = FontIdentifier("SFProDisplay-Medium")
}and then use them just like

You can shake any view just by calling
View().shake()And you could customize shake effect
View().shake(values: [-20, 20, -20, 20, -10, 10, -5, 5, 0],
duration: 0.6,
axis: .horizontal,
timing: .easeInEaseOut)
View().shake(-20, 20, -20, 20, -10, 10, -5, 5, 0,
duration: 0.6,
axis: .horizontal,
timing: .easeInEaseOut)or even create an extension
import UISwift
extension DeclarativeProtocol {
func myShake() {
View().shake(-20, 20, -20, 20, -10, 10, -5, 5, 0,
duration: 0.6,

timing: .easeInEaseOut)
}

// implemented. to be describedimport UISwift
class MyViewController: ViewController {
lazy var view1 = View()
override func buildUI() {
super.buildUI()
body {

View().background(.red).size(30, 20).centerXInSuperview().top(to: .bottom, of: view1, 16)
}
}
}import UISwift
// Just feel how easy you could build & declare your views
// with all needed constraints, properties and actions
// even before adding them to superview!
class LoginViewController: ViewController {
@State var email = ""
@State var password = ""
override func buildUI() {
super.buildUI()
view.backgroundColor = .black

}.edgesToSuperview(top: 120, leading: 16, trailing: -16)
}
}
func signIn() {
// do an API call to your server with awesome CodyFire lib 😉
}
}And you just need a few extensions to make it work
// PRO-TIP:
// To avoid mess declare reusable views in extensions like this
extension FontIdentifier {
static var sfProRegular = FontIdentifier("SFProDisplay-Regular")
static var sfProMedium = FontIdentifier("SFProDisplay-Medium")
}
extension Text {
static var title: Text { Text().color(.white).font(.sfProMedium, 18) }
}
extension TextField {
static var welcome: TextField {
TextField()
.height(40)
.background(.clear)
.color(.black)
.tint(.mainGreen)
.border(.bottom, 1, .gray)
.font(.sfProRegular, 16)
}
}
extension Button {
static var back: Button { return Button("backIcon").topToSuperview(64).leadingToSuperview(24) }
static var bigBottomGreen: Button {
Button()
.color(.white)
.font(.sfProMedium, 15)
.background(.green)
.height(50)
.circle()
.shadow(.gray, opacity: 1, offset: .init(width: 0, height: -1), radius: 10)
}
}
// PRO-TIP2:
// I'd suggest you to use extensions for everything: fonts, images, labels, buttons, colors, etc.
