I have a simple ViewController with a WKWebView, the page renders ok and there is no problem at first.
This is the code:
import WebKit
class SignIWkWebViewViewController: UIViewController {
var wkWebView: WKWebView!
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
wkWebView = WKWebView(frame: .zero, configuration: webConfiguration)
view = wkWebView
}
override func viewDidLoad() {
super.viewDidLoad()
startLoad()
}
// Receive Transfer Details and Results with a Delegate
private lazy var session: URLSession = {
let configuration = URLSessionConfiguration.default
configuration.waitsForConnectivity = true
return URLSession(configuration: configuration, delegate: self, delegateQueue: nil)
}()
var receivedData: Data?
private func startLoad(){
print("\(type(of: self)) \(#function)")
guard let url = URL(string:"https://itunesconnect.apple.com/login") else { fatalError("Can not get url") }
receivedData = Data()
let task = session.dataTask(with: url)
task.resume()
}
private func handleClientError(_ error: Error){
print("Error: \(error)")
}
}
extension SignIWkWebViewViewController : URLSessionDataDelegate{
func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: @escaping (URLSession.ResponseDisposition) -> Void) {
print("\(type(of: self)) \(#function)")
guard let response = response as? HTTPURLResponse,
(200...299).contains(response.statusCode),
let mimeType = response.mimeType,
mimeType == "text/html" else {
completionHandler(.cancel)
return
}
completionHandler(.allow)
}
func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive data: Data) {
print("\(type(of: self)) \(#function)")
self.receivedData?.append(data)
}
func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {
print("\(type(of: self)) \(#function)")
DispatchQueue.main.async {
//self.loadButton.isEnabled = true
if let error = error {
self.handleClientError(error)
} else if let receivedData = self.receivedData,
let string = String(data: receivedData, encoding: .utf8) {
self.wkWebView.loadHTMLString(string, baseURL: task.currentRequest?.url)
}
}
}
}
The issue start when I tap in the form field in the web page.
I set a breakpoint for UIViewAlertForUnsatisfiableConstraints
expr -l objc++ -O -- [[UIWindow keyWindow] autolayoutTrace]
And I got this error:

What is wrong in the code?

In https://appstoreconnect.apple.com I found the following message:

The updated Apple Developer Program License Agreement needs to be reviewed. In order to update your existing apps and submit new apps to the App Store, the Account Holder must review and accept the updated agreement by signing in to their account on the Apple Developer website.
I went to:

But I can not find the updated Apple Developer Program License Agreement needs to be reviewed.

(XXXXXXXXX) is my account ID at the bottom I can see Agreements (2), but If I click in any of then it just download a pdf file.
Where I need to go to accept it?

I am having issues with renewing subscriptions.From Session 705 Engineering Subscriptions WWDC 2018 - Does the User Have an Active Subscription?, I know that the way to answer to these questions is:
- Filter transactions by original_transaction_id
- Find transaction with the latest expires_date - Date in past shows user is not subscribed Subscription Period ---------------------------------------------------------> Time ---> USER HAS NO AN Active Subscription expires_date Today Subscription Period ---------------------------------------------------------> Time ---> USER HAS AN Active Subscription Today expires_date But I get the following data:
6 elements
▿ 0 : InApp ▿ expiresDate : 2020-05-02 21:31:29 +0000 ▿ 1 : InApp ▿ expiresDate : 2020-05-02 21:36:29 +0000 ▿ 2 : InApp ▿ expiresDate : 2020-05-02 21:41:29 +0000 ▿ 3 : InApp ▿ expiresDate : 2020-05-02 21:46:29 +0000 ▿ 4 : InApp ▿ expiresDate : 2020-05-02 21:51:51 +0000 ▿ 5 : InApp ▿ expiresDate : 2020-05-02 21:56:51 +0000 <====== transaction with the latest expires_datelet today = Date()2020-05-03 21:48:29 +0000Transaction with the latest expires_date is before Today.Why is this happening?
I have been doing some tests with the code to DownSampling / Scaling Image an Image from WWDC18 Session 416 iOS Memory Deep Dive.In this session they said that: - "Memory use if related the DIMENSION of the image, NOT file size.” - UIImage is expensive for sizing and resizing (will decompress memory first, internal coordinate space transforms are expensive) - Use ImageIO, it will work with out dirty memory (also API is faster)For my tests I used High Resolution Images with dimensions:1920 × 1080, 2560 × 1600, 3840 × 2160, 2560 × 1600, 4712 × 3133, 2560 × 1600 and 3072 × 2048.The following is the code that I used.import UIKit
struct ImageConverter{
static func resize(image: UIImage)-> UIImage{
let size = CGSize(width: 300, height: 300)
let renderer = UIGraphicsImageRenderer(size: size)
let resizedImage = renderer.image { context in
image.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
}
return resizedImage
}
}import UIKit
import ImageIO
struct ImageIOConverter{
static func resize(url: URL)-> UIImage{
guard let imageSource = CGImageSourceCreateWithURL(url as CFURL, nil) else {
fatalError("Can not get imageSource")
}
let options: [NSString: Any] = [
kCGImageSourceThumbnailMaxPixelSize: 300,
kCGImageSourceCreateThumbnailFromImageAlways: true
]
guard let scaledImage = CGImageSourceCreateThumbnailAtIndex(imageSource, 0, options as CFDictionary) else {
fatalError("Can not get scaledImage")
}
return UIImage(cgImage: scaledImage)
}
}import UIKit
class ViewController: UIViewController {
@IBOutlet weak var imageView: UIImageView! // Constraints Width: 300, Height: 300
let resource = "1"
let ext = ".jpg"
var imageNamed : String {
return resource + ext
}
@IBAction func uploadOriginalImage(_ sender: Any) {
guard let image = UIImage(named: imageNamed) else {
fatalError("Can not get image")
}
imageView.image = image
}
@IBAction func uploadImageScaledUsingUIImage(_ sender: Any) {
guard let image = UIImage(named: imageNamed) else {
fatalError("Can not get image")
}
imageView.image = ImageConverter.resize(image: image)
}
@IBAction func uploadImageUsingImageIO(_ sender: Any) {
guard let url = Bundle.main.url(forResource:resource, withExtension: ext) else {
fatalError("Can not get image url")
}
imageView.image = ImageIOConverter.resize(url: url)
}
}Effectively, I found that with ImageIO, the amount of memory is smaller, but at the same time I also noticed that using ImageIO the final image look to have lower quality than using UIImage.I mean, using UIImage the final image looks more to the original image than using ImageIO.I wonder if, Is this the expected result? (Lower image quality but also lower memory).
