Reply to Xcode Build Failure
@darkpaw: I have included snippet of my code below as reference. The 'width' parameter can be changed later ... However, same error would still show up: The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions ... struct ViewShelter: View { // TH: helps safely update UI. @State private var rowEven: Bool = true @State private var pathBlocked: Bool = true @State private var borderColorBackEnd: Color = Color.black @State private var borderColorBackEndOperation: Color = Color.black var body: some View { VStack (alignment: .leading){ ForEach(0...(ViewConstants.TARGET_STRING_BACK_0_DIMENSION-1), id:.self) { row in if let row_x = shelterViewModel.getShelter(row: row) as [RecommendationEntity]? { if let row_x_count = row_x.count as Int? { if row_x_count > 0 { let row_x_columns = Array(0...row_x_count-1) GeometryReader { geometry in HStack(alignment: .center) { ForEach(row_x_columns, id:.self){ column in self.rowEven = (row%2==0)

May be because image is upside down 😉 When you post a message, make it easy to use: image in correct orientation complete code so that one can test, in text, not only screenshot full error message Seems it is a problem to type check shelterViewModel.getShelter (row: row, column: column).productId == ViewConstants.LAYOUT_DUMMY_ what is productId type ? How are ViewConstants defined ? What is .LAYOUT_DUMMY_ ? Which type ? If it is not exactly the same as productId, then the error. Note: tests as shelterViewModel.getShelterOperationFormat() != true may be written !shelterViewModel.getShelterOperationFormat()

The error: The compiler is unable to type-check the expression in real-time generally means you're trying to do too many things in one place, and you should break it down a little. Firstly, to make it more readable, I'd put brackets around each ternary expression, for example: (row %2 == 0 ? Color.blue : Color.orange) so you can see which bits are enclosed. Then I'd split it out like this, creating a let for the various bits so they're individually evaluated prior to the larger expression. Also, I'd indent the code so it's more readable, putting the positive on the first line, and the negative on the next line, indented: let borderColor1 = (row %2 == 0 ? Color.blue : Color.orange) let borderColor2 = (shelterViewModel.getShelter(row: row, column: column).productId = ViewConstants.LAYOUT_DUMMY_ID ? Color.yellow : Color.green) .border( (shelterViewModel.getShelter0perationFormat() ? borderColor1 : (locationViewModel.getLocation(row: row, column: column) ? Color.red : borderCol

What is the first reliable position of the apple vision pro device?
In several visionOS apps, we readjust our scenes to the user's eye level (their heads). But, we have encountered issues whereby the WorldTrackingProvider returns bad/incorrect positions for the first x number of frames. See below code which you can copy paste in any Immersive Space. Relaunch the space and observe the numberOfBadWorldInfos value is inconsistent. a. what is the most reliable way to get the devices's position? b. is this indeed a bug? c. are we using worldInfo improperly? d. as a workaround, in our apps we set to 10 the number of frames to let pass before using worldInfo, should we set our threshold differently? import ARKit import Combine import OSLog import SwiftUI import RealityKit import RealityKitContent let SUBSYSTEM = Bundle.main.bundleIdentifier! struct ImmersiveView: View { let logger = Logger(subsystem: SUBSYSTEM, category: ImmersiveView) let session = ARKitSession() let worldInfo = WorldTrackingProvider() @State var sceneUpdateSubscription: EventSubscription? = nil @State var deviceTr

Zspeedaccuracy question
Hello everyone, I'm doing some work on validating some data to do with the zpseed functionality around corelocations, i've read up on the speedaccuracy field but the wording doesn't make sense to me. It says if its a positive number it is plus or minus the value in the zspeed column so would this be for example zspeed of 35 mps with an accuracy of 3 mps would it be 32 mps 38 mps or is it a range? so would it be anywhere between 32-38 mps. Or is it just plus or minus the 3mps and if this is the case how would it be worked out if its plus or minus when all the numbers will be a positive numbers as any negative numbers are deemed inaccurate ?

Reply to Xcode 16.3, an error is occurring in the String Catalog.
You are right that this situation can occur when migrating a .stringsdict to a .xcstrings. Specifically, the migrator only populates substitution argument numbers when they were previously explicitly-specified in the specifier. For example, if the original .stringsdict format string contained %1$#@VARIABLE@ instead of %#@VARIABLE@, the argNum would have been automatically set upon migration. The migrator does this as a safeguard to ensure that the built .stringsdict behaves identically at runtime to the original .stringsdict with regard to implicit argument numbers (which have complex rules at runtime). The String Catalog Editor does indeed hide the argument number and format specifier columns from the variable inspector when they are missing in the file. As you mentioned, editing the JSON or re-creating the string (or deleting it and letting it be extracted again) can get you out of this conundrum. I see that you filed a Feedback report about this. Thank you! That will help us evaluate whether we sh

Reply to Value column missing for Info.plist
open the Info.plist in its editor, by selecting Info.plist in the Navigator on the left. You'll find that the width of the Key field has been made very wide, and this is tied to the width of the Key field in the Info panel. If you can't see the column width handles in the Info.plist editor, you can scroll the whole display to the left to bring them into view. The Target's Info tab editor can't do that.

Value column missing for Info.plist
Here's what my Info.plist looks like: The problem here is that there is no value column. No where for me to edit the values. It's driving me insane. I can edit in a vanilla text editor, but it's annoying to use the auto complete feature here and then open a text editor to change the value. Anyone know why this could be happening? Am I just missing a setting toggle somewhere?

App Store Connect API discrepancies
In the Apple Summary Sales Report using App Store Connect API, you can get a daily count of downloads and re-downloads by using the 1F and 3F values in the Product Type Identifier column. You can then cross check the download numbers against the downloads reported in the Analytics section of App Store Connect. When looking at a month of data, the first time download numbers seem to line up exactly (1F in the API versus First-Time Downloads in Appstore Store Connect). There is a discrepancy though between reported re-downloads. The total units for 3F does not line up with the Redownloads numbers reported in the Analytics section of App Store Connect. The 3F redownloads from the API appear to be 60% higher for a month compared to the App Store Connect reporting interface. What could be going on here? Is there some type of de-duplication process run on the App Store Connect web report data that is not run on the data coming out of the App Store Connect API? Any insight would be greatly appreciated.

Debugging memory consumption in an Endpoint Security process
I have a launch daemon that's using the Endpoint Security framework which also is causing high memory usage (in Activity Monitor memory column shows for example 2GB and Real Memory 11MB) when building a big project in Xcode. Is it some kind of memory caching by the system? leaks -forkCorpse seems to not show any leaks. How can I attach with heap or Instruments without the process being killed with ENDPOINTSECURITY, Code 2 EndpointSecurity client terminated because it failed to respond to a message before its deadline?

Reply to Important item in Keychain seems to have disappeared (after years)
I don’t have a lot of expertise in keychain recovery. That’s not really an API issue, which is my focus, but more of a user-level issue, which is something for the folks over on Apple Support Community. However, I can answer some of this: [quote='829522022, rnikander, /thread/776581?answerId=829522022#829522022, /profile/rnikander'] Can I see every item name in login_renamed_1, without unlocking? [/quote] I’d ignore Keychain Access here and instead use the security tool. It’s very focused on file-based keychain. [quote='829522022, rnikander, /thread/776581?answerId=829522022#829522022, /profile/rnikander'] Is the entire data protection keychain in the file keychain-2.db? [/quote] Yes. Well, the entire data protection keychain for this specific user. Each user has their own data protection keychain. [quote='829522022, rnikander, /thread/776581?answerId=829522022#829522022, /profile/rnikander'] This is confusing me, since this looks to be file based as well [/quote] Sure. But all persistent storage on the Mac h
