How to detect iPod and iPhone device with Swift 3? - iphone

I would like to detect test device is iPod or iPhone. Now, I'm using this code.
if (UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.pad)
{ debugPrint("ipad show")
}
else
{
debugPrint("ipod show")
}
When I test with iPhone 7, it shows iPod. So, I would like to detect whether it is iPod or iPhone.
I don't want to install any additional pod to achieve this. I would like to implement this with simply and short code.
Can anyone help me please?


You can get it better by making an extension for UIDevice like:
public extension UIDevice {
var modelName: String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"
case "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"
case "iPhone8,1": return "iPhone 6s"
case "iPhone9,1", "iPhone9,3": return "iPhone 7"
case "iPhone9,2", "iPhone9,4": return "iPhone 7 Plus"
case "i386", "x86_64": return "Simulator"
case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
case "iPad3,1", "iPad3,2", "iPad3,3": return "iPad 3"
case "iPad3,4", "iPad3,5", "iPad3,6": return "iPad 4"
case "iPad4,1", "iPad4,2", "iPad4,3": return "iPad Air"
case "iPad5,3", "iPad5,4": return "iPad Air 2"
case "iPad2,5", "iPad2,6", "iPad2,7": return "iPad Mini"
case "iPad4,4", "iPad4,5", "iPad4,6": return "iPad Mini 2"
case "iPad4,7", "iPad4,8", "iPad4,9": return "iPad Mini 3"
case "iPad5,1", "iPad5,2": return "iPad Mini 4"
case "iPad6,7", "iPad6,8": return "iPad Pro"
case "AppleTV5,3": return "Apple TV"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
Usage: UIDevice.current.modelName
This will return the device model in string.
Try to use it like:
if UIDevice.current.modelName == "Simulator" {
print("Simulator")
}
else {
print("Real Device")
}

Function declares an opaque return type 'some View', but the return statements in its body do not have matching underlying types

I am getting the error where var view: some View{.
enum HomeButtons: Int, Hashable, CaseIterable{
case registerSignal = 1
case setAlarm = 2
case tV = 3
case test = 4
var image: String{
switch self{
case .registerSignal:
return "wave.3.backward"
case .setAlarm:
return "alarm.fill"
case .tV:
return "tv.fill"
case .test:
return "av.remote.fill"
}
}
var text: String{
switch self{
case .registerSignal:
return "Register Signal for TV"
case .setAlarm:
return "Set up Alarm"
case .tV:
return "TV and Sequences"
case .test:
return "Test Device"
}
}
var view: some View{ <------- Error is displayed here
switch self{
case .registerSignal:
return RegisterView(title: self.text)
case .setAlarm:
return Text("Set up Alarm")
case .tV:
return Text("TV and Sequences")
case .test:
return Text("Test Device")
}
}
}
struct RegisterView: View{
var title: String
var body: some View{
ScrollView{
ForEach(getTVList(), id: \.TVID){ TV in
NavigationLink(value: TV.TVID){
Text(TV.name)
}
}
}
.background(Color("ToledoGolden"))
.foregroundColor(.accentColor)
.navigationTitle(title)
}
}
I tried changing var view: some View to var view: any View the error went away but where I was calling HomeButtons.view I got this error message: Type 'any View' cannot conform to 'View'

You have to make the variable an #ViewBuilder and remove the return
enum HomeButtons: Int, Hashable, CaseIterable{
case registerSignal = 1
case setAlarm = 2
case tV = 3
case test = 4
var image: String{
switch self{
case .registerSignal:
return "wave.3.backward"
case .setAlarm:
return "alarm.fill"
case .tV:
return "tv.fill"
case .test:
return "av.remote.fill"
}
}
var text: String{
switch self{
case .registerSignal:
return "Register Signal for TV"
case .setAlarm:
return "Set up Alarm"
case .tV:
return "TV and Sequences"
case .test:
return "Test Device"
}
}
#ViewBuilder var view: some View{
switch self{
case .registerSignal:
RegisterView(title: self.text)
case .setAlarm:
Text("Set up Alarm")
case .tV:
Text("TV and Sequences")
case .test:
Text("Test Device")
}
}
}

Need help converting the following constants.h file to Swift

I am responsible for converting an iOS application written in Objective C to Swift. One file is the Constant.h has the following code written in it...
#define IS_IPHONE_4_OR_LESS (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)
#define IS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
#define IS_IPHONE_6 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
#define IS_IPHONE_6P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
I cannot import this file in the Objective-C bridging header.What is the Swift equivalent? Thanks in advance.

Since you want to figure out what device you are using, I think I would go about it this way:
import UIKit
public extension UIDevice {
var modelName: String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8 where value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"
case "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"
case "iPhone8,1": return "iPhone 6s"
case "iPhone8,2": return "iPhone 6s Plus"
case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
case "iPad3,1", "iPad3,2", "iPad3,3": return "iPad 3"
case "iPad3,4", "iPad3,5", "iPad3,6": return "iPad 4"
case "iPad4,1", "iPad4,2", "iPad4,3": return "iPad Air"
case "iPad5,3", "iPad5,4": return "iPad Air 2"
case "iPad2,5", "iPad2,6", "iPad2,7": return "iPad Mini"
case "iPad4,4", "iPad4,5", "iPad4,6": return "iPad Mini 2"
case "iPad4,7", "iPad4,8", "iPad4,9": return "iPad Mini 3"
case "iPad5,1", "iPad5,2": return "iPad Mini 4"
case "iPad6,7", "iPad6,8": return "iPad Pro"
case "AppleTV5,3": return "Apple TV"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
You call it like this:
let modelName = UIDevice.currentDevice().modelName

How to detect what device the user is using?

I know there was a thread about this already, but I'm asking this because it isn't working for me.
I put this code outside of my class, and it has no closures around it.
public extension UIDevice {
var modelName: String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8 where value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"
case "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"
case "iPhone8,1": return "iPhone 6s"
case "iPhone8,2": return "iPhone 6s Plus"
case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
case "iPad3,1", "iPad3,2", "iPad3,3": return "iPad 3"
case "iPad3,4", "iPad3,5", "iPad3,6": return "iPad 4"
case "iPad4,1", "iPad4,2", "iPad4,3": return "iPad Air"
case "iPad5,1", "iPad5,3", "iPad5,4": return "iPad Air 2"
case "iPad2,5", "iPad2,6", "iPad2,7": return "iPad Mini"
case "iPad4,4", "iPad4,5", "iPad4,6": return "iPad Mini 2"
case "iPad4,7", "iPad4,8", "iPad4,9": return "iPad Mini 3"
case "iPad5,1", "iPad5,2": return "iPad Mini 4"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
So, up in my didMoveToView, I ran this code:
if UIDevice.currentDevice().modelName == "iPhone4,1" {
print("yes")
repeatObstaclesOnPhone()
}
I ran the app then on the iPhone 4S simulator and nothing happened. Can someone help me figure this out?

Swift Sprite Kit In App Purchase

I have a button in an SKScene (using Swift) -- "Add Puzzles"
When the user clicks this button, I want to go to a UIView Controller or UI Scene so that I can implement In App Purchase code... (SkScenes are subsets of UIViews and cannot run the code...)
Does anyone have a basic idea how to do this...
I am a little inexperienced at this... I have used cocos2d and now Sprite Kit and have always set everything up manually and have very little experience with .xib files and view Controllers...
Does anyone know the basic idea of how to do this? Thanks for any help!
ANDY

You can set-up In-App-Purchases inside of an SKScene, You may need to tweak some code but it will work. Here's an example
import Spritekit
import Storekit
class Store:SKScene, SKProductsRequestDelegate, SKPaymentTransactionObserver {
override func didMoveToView {
// Set IAPS
if(SKPaymentQueue.canMakePayments()) {
println("IAP is enabled, loading")
var productID:NSSet = NSSet(objects: "bundle id", "bundle id")
var request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID)
request.delegate = self
request.start()
} else {
println("please enable IAPS")
}
}
// 2
func btnRemoveAds() {
for product in list {
var prodID = product.productIdentifier
if(prodID == "bundle id") {
p = product
buyProduct()
break;
}
}
}
// 3
func btnAddCoins() {
for product in list {
var prodID = product.productIdentifier
if(prodID == "bundle id") {
p = product
buyProduct()
break;
}
}
}
// 4
func removeAds() {
println("ads removed")
}
// 5
func addCoins() {
println("added 50 coins")
}
// 6
func RestorePurchases() {
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
var list = [SKProduct]()
var p = SKProduct()
// 2
func buyProduct() {
println("buy " + p.productIdentifier)
var pay = SKPayment(product: p)
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().addPayment(pay as SKPayment)
}
//3
func productsRequest(request: SKProductsRequest!, didReceiveResponse response: SKProductsResponse!) {
println("product request")
var myProduct = response.products
for product in myProduct {
println("product added")
println(product.productIdentifier)
println(product.localizedTitle)
println(product.localizedDescription)
println(product.price)
list.append(product as SKProduct)
}
}
// 4
func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue!) {
println("transactions restored")
var purchasedItemIDS = []
for transaction in queue.transactions {
var t: SKPaymentTransaction = transaction as SKPaymentTransaction
let prodID = t.payment.productIdentifier as String
switch prodID {
case "bundle id":
println("remove ads")
removeAds()
case "bundleid":
println("add coins to account")
addCoins()
default:
println("IAP not setup")
}
}
}
// 5
func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) {
println("add paymnet")
for transaction:AnyObject in transactions {
var trans = transaction as SKPaymentTransaction
println(trans.error)
switch trans.transactionState {
case .Purchased:
println("buy, ok unlock iap here")
println(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID {
case "bundle id":
println("remove ads")
removeAds()
case "bundle id":
println("add coins to account")
addCoins()
default:
println("IAP not setup")
}
queue.finishTransaction(trans)
break;
case .Failed:
println("buy error")
queue.finishTransaction(trans)
break;
default:
println("default")
break;
}
}
}
// 6
func finishTransaction(trans:SKPaymentTransaction)
{
println("finish trans")
}
//7
func paymentQueue(queue: SKPaymentQueue!, removedTransactions transactions: [AnyObject]!)
{
println("remove trans");
}
You would call the removeAdsButton() or whatever when you want to make a purchase.

I can confirm the bug goes away when you set a Launch Screen.
I kept my launch images, and added MainStoryboard to Launch Screen and the simulator recognized the devices correctly.

It's better not to bind your code with device types. This will lead to inflexible convoluted one. Apple wants you to think about sizes not devices. In case you need to have special sizes for devices larger than iPhone 5 such as image or font sizes, I would recommend to create a normalize class with a multiplier that grows your base size by a certain percent based on the relation between the iPhone 5 screen width and the current device size.
let BaseWidth : CGFloat = 320
class Normalizer: NSObject {
//scale value proportional to the screen width
class func normalize(value:CGFloat,multiplier : CGFloat = 1,maxDelta:CGFloat = 1024) -> CGFloat{
let screenWidth = UIScreen.mainScreen().bounds.size.width
let percent = (screenWidth - BaseWidth)/screenWidth
let normalizedValue = value * (1 + percent) * multiplier
return min(normalizedValue, value + maxDelta)//capped by a max value if needed
}
}
So in your code you will do something like that:
value = Normalizer.normalize(30)

UIDeivce extension with Swift 3+ syntax.
public extension UIDevice {
var iPhone: Bool {
return UIDevice().userInterfaceIdiom == .phone
}
enum ScreenType: String {
case iPhone4
case iPhone5
case iPhone6
case iPhone6Plus
case iPhoneX
case Unknown
}
var screenType: ScreenType {
guard iPhone else { return .Unknown}
switch UIScreen.main.nativeBounds.height {
case 960:
return .iPhone4
case 1136:
return .iPhone5
case 1334:
return .iPhone6
case 2208, 1920:
return .iPhone6Plus
case 2436:
return .iPhoneX
default:
return .Unknown
}
}
}
Sample usage:
switch UIDevice().screenType {
case .iPhone4, .iPhone5:
// Code for iPhone 4 & iPhone 5
break
case .iPhone6:
// Code for iPhone 6 & iPhone 7
break
case .iPhone6Plus:
// Code for iPhone 6 Plus & iPhone 7 Plus
break
case .iPhoneX:
// Code for iPhone X
break
default:
break

I encountered the problem while migrating from an iOS 7 project to a iOS 8 project, since I didn't add a launch screen scene to my project.
In this case the screen size for iPhone 6 and 6+ are as iPhone 5.
See from apple documentation; You use a launch XIB or storyboard file to indicate that your app runs on iPhone 6 Plus or iPhone 6.
