Logically, this should be inserted once user has accepted tracking from your app. Have a look here: https://developer.apple.com/documentation/apptrackingtransparency

Is it possible from a localized french VALUE, to get corresponding VALUE in base language? You may have another way (I do not recommend, but it will require less change to your code). When you get the answer (in French or whatever language), build the array of localized strings from original array let localizedStrings = originalArray.map() { NSLocalizedString($0, comment: "") } Search for the answer and get the base string var baseAnswer = "" if let index = localizedStrings.firstIndex(of: answer) { baseAnswer = originalArray[index] } Do what you need with baseAnswer

So, does it work now ? I hope so. If so, please don't forget to close the thread.

Could you show the code ? Difficult to say anything without looking at it.

Here is what I get from a working project (Xcode 12.4) ?xml version="1.0" encoding="UTF-8"? document type="com.apple.InterfaceBuilder3.CocoaTouch.Storyboard.XIB" version="3.0" toolsVersion="17701" targetRuntime="iOS.CocoaTouch" propertyAccessControl="none" useAutolayout="YES" useTraitCollections="YES" useSafeAreas="YES" colorMatched="YES" initialViewController="BYZ-38-t0r" device id="retina6_5" orientation="portrait" appearance="light"/ dependencies deployment identifier="iOS"/ plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="17703"/ capability name="Safe area layout guides" minToolsVersion="9.0"/ capability name="System colors in document resources" minToolsVersion="11.0"/ capability name="documents saved in the Xcode 8 format" minToolsVersion="8.0"/ /dependencies scenes !--First View Controller-- scene sceneID="tne-QT-ifu" objects viewController storyboardIdentifier="FirstView" id="BYZ-38-t0r" customClass="FirstViewController" customModule="simpleTest" customModuleProvider="target" sceneMemberID="viewController" I note the following differences: toolsVersion="17701" vs "18122" for you But in your first post, with 12.0 it was: Plugin Version = 17156, which is anterior to mine. In my case I also have:         deployment identifier="iOS"/ May be you have included Mac in deployment info ? In my case:         plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="17703"/ In yours     plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="18093"/ So I would (on a test project): do an option-clean build folder remove Mac deployment (if you did set it) change useAutolayout="YES" to "NO" You should file a bug report with all this information.

That seems to be a frequent bug. https://developer.apple.com/forums/thread/663465 This video (no sound!) which shows how it works on 13 and no way on 14. https ://www.youtube. com/watch?v=F2ojC6TNwws You should contact Developers Support or even burn a DTS ticket if critical.

It is normally not possible, as maximum target with Xcode 10.1 is iOS 12. haven't you an iPhone with iOS 12 ? have a look here, you may find some advice: https://developer.apple.com/forums/thread/115043 In any case, if you want to publish some day on the AppStore, you'll need Xcode 12 at least.

In fact, SKPaymentQueue.default().storefront itself is nil.

What is the complete error message you get ? Do you query query a MatrixMixer AudioUnit ? If so, may have a look here: https://stackoverflow.com/questions/38315905/kaudiounitproperty-matrixlevels-in-swift Note: line 1, you don't need all the cast. In addition, if not url, it will cause compiler error. So, useless. if url is effectively a URL, just write let avasset = AVAsset(url: url)

Did you try the usual clear PRAM ? https://support.apple.com/en-us/HT204063 or Resetting the system management controller (SMC) https://support.apple.com/en-us/HT201295

I found this older thread where exact same problem showed (with the same cache directory). Solution proposed was: https://developer.apple.com/forums/thread/123204 having the same crash on XCode 11.2.1 . I went on to "Show package contents" of the ".xcworkspace" workspace directory and deleted "xcuserdata" folder. This resolved the crash for me.

I reached my limits… Hope this can help, or at least give some hints: https://stackoverflow.com/questions/50756907/how-to-convert-ecdsa-der-encoded-signature-data-to-microsoft-cng-supported-forma

Seems you are using an old beta. Download Xcode 12.4 (or 12.5 if you run BigSur) Can download 12.4 here: https://developer.apple.com/download/more/ And try open the project. You should also test that a new project works. If that's not OK for your project: First make a copy of your project and work on this copy. Can you identify the object : MCj-i5-HUl ? You could open the storyboard in an editor to search for 'MCj-i5-HUl' Try to remove completely this object, which should remove all constraints Then try to reopen the project And recreate the deleted object.

In the test I did, it did work with : @ObservedObject var locationManager = LocationManager()

To be more precise. I copied your exact code, except for line @EnvironmentObject var sessionManager: SessionManager that I commented out.
