How to retrieve required Apple Pay parameters for PayFort payment request in Swift?
I'm integrating Apple Pay with PayFort in a Swift iOS application, and I’m currently working on preparing a valid purchase request using Apple Pay, as described in PayFort’s documentation: 🔗 https://docsbeta.payfort.com/docs/api/build/index.html?shell#apple-pay-authorization-purchase-request The documentation outlines the following required parameters: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod apple_displayName apple_network apple_type Optional: apple_applicationData I understand these should be derived from the PKPayment object after Apple Pay authorization, but I’m having trouble mapping everything correctly. Here’s what I’m seeing in code: payment.token // Returns something like: <PKPaymentToken: 0x28080ae80; transactionIdentifier: "..."; paymentData: 3780 bytes> payment.token.paymentData // Contains 3780 bytes of encrypted data payment.token.paymentData.base64EncodedString() // Returns a long base64 string, which at first glance seems like it could be used for apple_data, // but PayFort doesn't accept it as-is — so this value appears to be incomplete or incorrectly formatted I can successfully retrieve the following values from payment.token.paymentMethod: apple_displayName apple_network apple_type However, I’m still unsure how to extract or build the following in the format accepted by PayFort: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod These may be contained within the paymentData JSON, but I’m not sure how to decode it or if Apple allows decrypting it in a way that matches PayFort’s expected format. How can I correctly extract or build apple_data, apple_signature, and apple_header from the Apple Pay token? Also, how should I handle the decryption or decoding (if necessary) of paymentData to retrieve values like apple_transactionId, apple_ephemeralPublicKey, and apple_publicKeyHash? If anyone has successfully set this up or has example code that bridges Apple Pay and PayFort’s expected request format, it would be super helpful! Thanks in advance 🙏

Deep link to a file in Xcode
Hi, is there documentation on how to write a deep link that will open Xcode on a given file, and optionally a line number? I know about xed, and I would like exactly that functionality, but in link form, so that I can link to a certain file from an app such as Obsidian or from a README.md file. I checked Xcode's Info.plist and it understands several URL schemes, the most promising of which is xcode://, which successfully launches the app, but no matter what I tried, I get an error dialog telling me that Xcode did not understand the URL. Any help on this topic would be greatly appreciated. Victor

Xcode inserts unexpected apostrophes into Markdown and XML files
In Xcode, when you type a word like "don't", a second apostrophe is automatically inserted after the word and you have to manually delete it. Repro steps: Create a new empty Markdown file or XML file. Open the file in Xcode. Type the word “don’t”. Expected behavior: The word “don’t” appears. Observed behavior: The word “don’t” appears, followed by an extra single quote.

I have a bone to pick with Xcode
Despite Xcode being the one and most used IDE for iOS, it is far from perfect. I have used many tools in my career and here are some features, that would make it much better or what I miss from other IDEs. I encourage others to chip in discussion and lets all hope, Apple starts to improve Xcode. Will put each issue in separate comment below. Slow debugger: not sure what bloat Xcode has or what it is doing, but sometimes it can take more than 10 seconds from breakpoint firing to actually see values. Moreover when debugging SwiftUI or something objC I have to drill down to see value of property or use po and p command and hope it works. SwiftUI views and states are a big pain to debug, to see what is changing a value I have to always use didSet trick or some other black magic. Is it too hard to make it easier? Breakpoints with condition can take up to 1 minute to load and I have M1 Max MBP. Just tried cursor IDE few days ago and breakpoints are much faster and without too much bloat in variable inspector.

WatchOS Xcode 16.4 to sample live RR intervals from the PPG sensor ERROR
Hi, I am getting an error stating "Argument passed to call that takes no arguments". I want this Apple Watch App to measure and store RR Intervals from the PPG sensor on the Apple Watch for Heart Rate Variability calculations. Please help me fix this, I can't figure it out. Here is my code: heartbeatQuery = HKHeartbeatSeriesQuery(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async }) // End query data handler // --- END OF PROBLEMATIC INITIALIZER --- // Execute the query if it was created successfully It recommends the fix as removing this part: '(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async })' But after I remove that it says "Cannot assign value of type 'HKHeartbeatSeriesQuery.Type' to type 'HKHeartbeatSeriesQuery'" PLEASE HELP ME Thanks

Is it possible to set the Derived Data location differently for different projects?
Within Xcode's settings location section is a drop down menu to switch between setting the derived data location to be default, relative or custom. However its a global setting. I work on more than one project simultaneously, and for one of them I want the location set to relative, but default for all the others. Is there any way of achieving that?

Xcode and Supabase Package
Hi All, I'll start by saying i am complete beginner when it comes to coding/ developing. So please be easy on me, im also using AI tools to help and learn so apologies if what im saying doesnt make sense. The error im getting is /Services/SupabaseManager.swift:47:29 Cannot find 'GlobalOptions' in scope From AI tells me 'GlobalOptions' is defined a types.swift file in the supabase package public struct GlobalOptions: Sendable { /// Optional headers for initializing the client, it will be passed down to all sub-clients. public let headers: [String: String] /// A session to use for making requests, defaults to `URLSession.shared`. public let session: URLSession /// The logger to use across all Supabase sub-packages. public let logger: (any SupabaseLogger)? public init( headers: [String: String] = [:], session: URLSession = .shared, logger: (any SupabaseLogger)? = nil ) { self.headers = headers self.session = session self.logger = logger } } From what i can see i have added the supabase package successfully, following this guide - https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app Here are some screenshots of my xcode to show the added package.

Xcode: Unknown Name
I wanted to see if anyone else is having this issue. We are trying to update our app, but on XCode, there is this error message showing: Team: Unknown Name (Code). There is a check in "Automatically Manage Signing". Normally, Apple provides this information to XCode automatically but this time it seems like it's either not sending it or not receiving it. If anyone knows what is happening here, any suggestion/advice would be greatly appreciated! Thank you!

The Xcode account often logs out automatically when I use fastlane.
I used fastlane to package and upload the test package to TestFlight. However, the account in Xcode is often logged out automatically without any prompts. In Xcode, I logged in with the developer account to automatically manage certificates, provisioning profiles, signatures, etc. For the fastlane upload, I used a Application-specific passwords. Does anyone know what could be the reason? I'm almost driven crazy.
