I'm trying to create a frosted glass background effect. I've seen many tutorials and the way to go seems to be using something like .foregroundStyle(.thickMaterial) or .background(.thickMaterial).
However, Xcode just does not recognise any of those. I get the error: Cannot infer contextual base in reference to member 'thickMaterial'.
I don't think this is a problem with my code because I could start a completely new project and copy the example from the Hacking With Swift website, but I still get that error.
What could be the issue?
I'm using Xcode version 12.4.

Having an iOS 12 model rending issue.
My app loads OBJ models with associated MTLs and textures.
On iOS 11 we were able to load up the models and they looked good:
On iOS 12, they look completely different:
We are able to make some changes after the model loads initially to make it look good, but it takes time for the iPhone to load the better looking version.
Has anyone heard about/experienced this issue and know what has changed in iOS 12 (and potentially MacOS Mojave) that is causing it?
There might be two issues: 1- texture issue (as seen in chair on left) and 2- Material/MTL issue as seen in the ‘delivery drone’ on the right
I don't have any code at this moment as I am not one of the developers on the project - I have been tasked with reaching out here. If you have any questions regarding the specific code I could definitely try to get some to show here. It seems to me like this might not be a code issue or bug, but rather some settings that have to changed due to changes made in iOS 12, but I can't find documentation for something that matches this.
I know this is not an answer, but I was asked for a screenshot. For the moment I use the OpenGL renderer instead of Metal as a workaround.
I solve the same issue by convert .obj file to .scn files in Xcode, and use this scenes as nodes. Editor -> Convert to SceneKit file format (.scn)

Do anyone know the workaround for the build error on Xcode?
All suggestions are welcomed.
E.G: Impossible in that way, Possible with Objective-C, not Swift
Environment:
Swift:3.2, Xcode:9.2, Unity:2017.3.0f1, iOS:11.2.1
Condition:
I’m trying to make Native Plugin for Unity using Swift like this.
Unity C# -> Objective-C -> Swift
For now, I could access the iPhone camera roll from Unity.
The Project Name is GetDepthSample here.
Error Detail:
As soon as I add ARSessionDelegate on the class definition, I got the following error.
CameraRollSample.swift
Other Information:
GetDepthSample-Swift.h (generated automatically on Xcode) shows the following error.
GetDepthSample-Swift.h
It’s possible to jump to Definition of the protocol ARSessionDelegate.
Not only ARSessionDelegate but also MetalKit shows the similar error.
The original Unity Project

Many thanks!
Looking at the header that you posted in the comment, it seems to me that maybe you need to include the ARKit framework in the project settings in Xcode. Although this generally tends to work automatically clearly something in your setup has that missing.
I have been working on my first iOS/Swift application for the past month or so, and have created all of my class declaration files (i.e. my .Swift files) in my main project folder. I would really like to use live views in my app, because as of right now I cannot build/run the app at all due to errors I don't know how to fix (I'll be posting about those later today in hope of finding someone who can help me fix them).
What would be the best way to go about converting all of my views into embedded frameworks so that I could use the Live Views feature of Xcode ? I am running Xcode 7 and wrote my app in Swift 2.0
Thanks
You apparently don't need to use frameworks for that anymore. At least it works just fine in Xcode 7 for me - for classes that are part of the main project. Just mark your class as #IBDesignable.
But in order to show the preview, your code needs to be able compile, so you will need to resolve your issues first.
After I installed the latest version of xcode i'm having a very annoying issue.
While I'm coding, xcode goes nuts. Without me doing anything weird, just typing code, xcode stop recognizing classes.
For example: I want to add UITableViewDelegate to my class, but it doesnt recognize it. After i type it manually sometimes it recognize it and it is shown in purple, some other time it doesnt. But both times it won't really consider it, so if I try to write down a method of that delegate, it won't show it.
Other times if I try to call a variable of a certain class, while trying to autocompleting it, it shows <>.
Other times if I try to call any class, let's say I try to type var test = UIActionSheet, it just shows a few elements in the autocomplete list (raw types, primitives, the classes of my main project, but it doesn't show the majority of classes).
It's like it's missing the documentation and the link with the main frameworks...
I'm working on a simple tabbed app from yesterday and it's the 3rd time i started all over because of this issue, thinking that starting over would fix the issue, but it's not working.
If i open a different project while the issue is going on, the other project works ( but i recoded all over my app so it's not that one the issue, and i also have the same issue on other project... it just doesn't affect 2 project at the same time )
i tried deleting derived data
i tried restarting both xcode and the comp
What's going on?
Here are two screenshoots where you can see what's happening:
I had the same problem earlier.
Exit Xcode and delete Derived Data folder here ~/Library/Developer/Xcode
Restart Xcode and you should see the autocomplete working again.
You have to learn how to take it apart and put back together.
Either reinstall Xcode, if it doesn't help, create a new project.
Then copy source files one by one and see when it breaks.
Freshly install the XCode IDE version 6.1
Use CMD + F to find all _element.
Check that if you named one variable _element
The following code may reproduce the error:
class _element:NSObject {
}
let _element:UIImage = UIImage()
// type _element under this line
I'm not sure if I am the only one experiencing this program, but I have tried searching and have not been able to find anyone in my current situation. I downloaded Xcode 6 beta and was interested in Extension programming for iOS 8. However, I have been unable to locate the extensions in my project templates when creating a new project in Xcode, I saw a YouTube video (unrelated to extension programming) but I did notice that the option was not there for the said video. Now, I have had a look through the contents of the Xcode 6 beta package and have been able to locate the actual templates themselves, so I have no doubt they are present, it just seems that they are not actually being loaded.
For the record, I also downloaded some example custom keyboard code from GitHub in order to see whether Xcode will recognise it and it does, going as far as actually displaying the 'E' icon beside the build target. I should also mention that I do have a build of Xcode 5 also present on my machine.
Is anyone else experiencing this issue, or does anyone know how to overcome it?
Thanks
You create a extension by creating a new target in an existing project.
Check this link for more information
I had the same problem. The solution was to not try to add the extension in File/new/File... menu but in File/new/Target... menu.
You can add extension to any existing project.
