the latest iso. Do you mean the latest iOS ?

If it says it is installing iOS update, YES, let it finish (and put on a charger, that may be required to proceed).

Note that if you have a space before the = sign, you must have one after.

Could you show TestViewController func ?

You could also change your TestViewController to return a String. This name TestViewController is really confusing. Do you create a ViewController here as the name suggests. A name like testScore would be more appropriate (starting with lowerCase).

AFAIK, that's not possible. You risk a refusal as a spam app. Appstore is not a platform for testing. You should publish (even in TestFlight), an operational app, maybe lacking some features. If the first publication is for TestFlight, why would you need to change the name and appID ? If it is a confidentiality of the name, you can change the app name only, not its ID.

How would you make the difference between ambience noise and someone speaking in a call ?    Did you see this ?     https://stackoverflow.com/questions/66947908/how-to-detect-external-microphone-by-swift-5-in-simulator

You should show more. We need to know what SomeValue are. Please show the real code. But probably: You have defined and Array of Double Then you try to give it a value of Double, not array.

Yes it is possible. Just don't forget to name it with a different name, such as Xcode 12.5 It is better to have Xcode on the main drive.

Did you give up ? You did not provide the needed information.

Does it work now ? If so, please close the thread.

Do you try to install Xcode 13 ? 42 GB may be just a bit too limited. Usually, 50 GB may be needed (because there are a lot of large temporary files in the process). 31.58 GB for the app itself 12 GB for the zipped file some more may be needed during installation. You could try to download directly here : https://developer.apple.com/download/more/

When you post code, please post real code (this is not) and use code formatter tool. extension DateFormatter { convenience init(dateFormat: String) { self.init() self.locale = Locale.current self.timeZone = TimeZone.current self.dateFormat = dateFormat } } extension Date { func getCurrentTimestamp()->String{ let formatter = DateFormatter() formatter.timeZone = TimeZone.current formatter.dateFormat = "yyyy-MM-dd HH:mm:ss" return(String(describing:formatter.string(from: self))) } } let dateFormatter = DateFormatter(dateFormat: "HH:mm") let myDate = dateFormatter.date(from: "10:30") print(myDate) // 2000-01-01 08:55:00 +0000 print(TimeZone.current)// "Europe/Berlin" print(Locale.current.description)// "de_DE (current)" print (Date().getCurrentTimestamp())// 2018-10-14 03:56:23" Explain also clearly the problem. With this code I get: Optional(2000-01-01 09:30:00 +0000) Europe/Paris (fixed (equal to current)) en_US (current) 2021-10-13 17:43:40 not 2018 year

I want to study how to create my first URL Could you explain ? What did you try so far ?

Please show the complete code. What is the use to redefine each value, such as let NewHour = newHour instead of using only newHour ? Note also that Swift var should begin with lowercase. If the problem is you need Double, maybe you have to:         let calculatePace = Double(NewTime[0]*3600 + NewTime[1]*60 + NewTime[2]) / Double(3600 * NewDistance) or         let calculatePace = Double(newHour*3600 + newMinute*60 + newSeconds) / Double(3600 * NewDistance) This will give hour/km, is it what you want ? If you want km/h, it should be the reverse:         let calculatePace = Double(3600 * NewDistance) / Double(NewTime[0]*3600 + NewTime[1]*60 + NewTime[2]) or         let calculatePace = Double(3600 * NewDistance) / Double(newHour*3600 + newMinute*60 + newSeconds) But once again, tell what you expect, what you get, where is eventual crash and show comprehensive code. And don't forget to close the thread on the correct answer once you got it.
