18e5140k is just the iOS build number. What is the complete message you get. Did you try reboot both iPhone and Mac ? Note: in the documentation for beta, it is stated that you do it at your own risks… It is not a very good idea to do thins on a device you need, you should do it on a scapegoat iPhone…

Did you solve your issue ?

When do you get this ? What is the problem if they refer to iOS 14.4. Is it what you have ?

Did you do an option-clean build folder ? Then close XCode and reopen. Or even remove all Derived data ?

Ok, let close it. It does not print the segue.identifier it prints the delegate is nil and then it just crashes again. It does not matter what I change my segue.identifier too. But you did not show (unless I missed something), where is this print statement.

Without viewing the details of your setup, very hard to say. You have certainly something ill defined, as I used what I described in many cases and it worked perfectly. If you want to post an email for sharing files, we can do it.

You should move your question to MacOS tag. iOS is not the right tag. You should not restart during system update, even if it seems to be very long. You risk to corrupt badly the installation.

What I would do : create UIViews (not stackView) in each, add a label and a stepper set the constraints as needed add these UIViews in the stackView Note: You could subclass UIView, (call it LabelStepperView for instance) to have a label and a stepper, and have code to update label when stepper changes. That would give a more structured code.

SDK are included in Xcode, AFAIK, they are not available separately. What is your precise problem ?

Did you try creating a new project, just empty. If no crash, that means problem is in your code (unlikely though to cause such a crash) If it crashes, that probably mean you have an Xcode install problem. Reinstall.

Where exactly is it listed as english app ? On which country appstore do you look at it ? Italian appstore ? What is the development language of your app ? Maybe english by default. To see this: select the Project (blue icon on the top of Xcode file browser) Select Project (not Targets) Select Info tab Look in Localization part

NSDatePicker, but it only seems to come in a single size What size or format do you want to change ?

What you can probably do is create a window which is full screen size, give it a semi transparent background and declare it as non sizeable. You will have then to keep your other windows on top. That would give the impression that desktop is blurred (until you quit your app or switch to another one of course). But I don't think it is possible to blur the screen background itself. May I ask: why do you want such an intrusive and, at first sight, not user friendly, feature ?

Did you try the workaround I proposed ?

What are those installation files ? Are they user documentation ? If so, you can include a pdf file in your app resources (or may be leave it available on your web site). If it is a configuration file, why not include a json ? I think this would not cause any problem. And it would be easy to use it directly in the app. Note: I advise you to explain clearly in the app submission (in the reviewer information section) what those files are, what they are used for… That will create trust on reviewer's side.
