Side by side.Not only, I would like to use the same function to create a matrix of NSImage (MAC OS X app, not iOS app).I am looking a way to create a page of images icons in X rows and Y columns (like a matrix) , but at the moment I do not have any idea from where to start (Swift beginner....)Any help is gold for me...

I am looking a way to create a page of images icons in X rows and Y columns (like a matrix) …It sounds like an NSCollectionView would be a good match here, using NSImageView for the cells.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com

The persistentContainer.viewContext is the managed context -while there are no problems with Objective-C, the same code crashes in Swift. For example, create a simple application - Entity User with firstName, lastName String,a table view with two corresponding columns, bind an array controller to App Delegate' persistentContainer.viewcontext, fetching entity User, and you will get the error. Try it it with Objective-C, it has no problems.

What you would want to do is use the fetchUserRecordID function on CKContainer which will give you an opaque record ID for the signed in user. It's not their email address, but it's a unique identifier you can use to identify a user. This is the same value that would show up in the CK dashboard under the User column. When you get the completion handler called, you can ask the CKRecordID for the recordName, and that's the string you'd want to have. Again, it's completely opaque to you, it's just an identifier. As a previous poster stated, you don't have programmatic access to the user's email address since that would be a privacy issue.

As with most things in programming, it pays to break down your problem into parts:Reading a fileBreaking it into linesBreaking the lines in columnsConverting a string to the appropriate data valueI’ll cover each in turn.If you’re just getting started, a good place to start is a command line tool. This avoids the need for dealing with file selection dialogs, the App Sandbox, and so on. Here’s a tiny shell command line tool that’ll get you going:import Foundation func process(string: String) throws { … your code here … } func processFile(at url: URL) throws { let s = try String(contentsOf: url) try process(string: s) } func main() { guard CommandLine.arguments.count > 1 else { print(usage: (CommandLine.arguments[0]) file...) return } for path in CommandLine.arguments[1...] { do { let u = URL(fileURLWithPath: path) try processFile(at: u) } catch { print(error processing: (path): (error)) } } } main() exit(EXIT_SUCCESS)Note I’ve made some shortcuts here (like assuming the file is UTF-8 and printing errors to s

Well, I was reading you updated your IAPs and assumed they had been approved before.If those IAPs have never been approved before, then the game is different: I guess these are also the first IAPs of your app; for the first IAPs of one app those have to be submitted together with an app binary. After you prepared your actual in-app purchases for review (which I read you did), you have to upload a new app binary and then from iTunes Connect select that binary and add the new IAPs to that new app binary and finally send the app binary into review. Here more about that:Submit an in-app purchase for the first timeFrom the homepage, click My Apps, then select your app. The App Store page opens with App Information selected.In the left column, click the app version you want to submit.On the right, scroll down to the In-App Purchases section, then click the Add button ➕ next to In-App Purchases.And about IAP issues in general: yes, there are some IAP review issues once in a while, especially early after new
