Have you considered using Operations, and an OperationQueue? Setting maxConcurrentOperationCount = 1 will execute your operations sequentially.

Apple say: For all distribution methods except TestFlight, choose the following options to enhance your chances of discovering a bug that manifests only in the release build: Set App Thinning to “All compatible device variants”. Check “Rebuild from Bitcode”.

From Xcode: Window > Devices and Simulators > Simulators This gives you a list of Simulators, where you can add or remove.

The key line is: let decodedData = try JSONDecoder().decode(DetailResponse.self, from: recepieData) ...where you try to decode a DetailResponse from json. struct DetailResponse:Codable {     let yields:String     let name:String } If you can share some sample json (that is failing to decode), then it will be possible to comment on what might be going wrong.

You may have got a bit confused, between Operations and OperationQueue. Start simple: let operation1 = BlockOperation {     Thread.sleep(forTimeInterval: 5) print("Operation 1 completed") } let operation2 = BlockOperation { print("Operation 2 completed") } operation2.addDependency(operation1) let queue = OperationQueue() queue.addOperation(operation1) queue.addOperation(operation2)

As I said earlier, setting maxConcurrentOperationCount = 1 will execute your operations sequentially. So they will execute in the order you add them to the queue. In that case, you don't need to set the dependencies.

I think it's worse than Scott suggests, your JSON seems to be very badly formed. It's missing separators between items, and some of the items are ambiguous. This works: { "name":"Vegan ****** Cashew Mac", "yields":"Servings: 6" } Maybe you have chopped up your JSON, and posted something quite different to the original data?

Use git, with a remote repository, then you get all the benefits of source control. e.g. you can review your remote worker's changes, before merging them into the main project. I use git for even the smallest Xcode project now, but for a team, it's a no-brainer. Lots of help is available online.

It looks like you have turned on "split keyboard". To put it back to normal: Tap and hold the "keyboard" key (at the bottom right), and select "Merge" or "Dock and Merge"

Your cell is of type UITableViewCell. UITableViewCell has no property called nameLabel. Perhaps you expect cell to be an ItemTableViewCell? You don't show your code, so I'm guessing, but perhaps ItemTableViewCell has a property called nameLabel? If so, when you dequeue your cell, you would have to cast it to the correct type.

Put the comment above the function declaration! /// this is just an example of markdown. /// /// - Parameters: ///     - someString: A simple string. ///     - someInteger: A simple integer func myFunction(someString: String, someInteger: Int) {

As I see it: On launch, there is no path status So when we get the path status, it is considered to have changed You can always check if it has really changed in pathUpdateHandler, by comparing the new status with the previous status (which you save at the end of pathUpdateHandler).

To enable the ShazamKit service for an app... On the Apple Developer website In Certificates, Identifiers & Profiles, choose your app's Identifier Select "App Services", then tick "ShazamKit"
