QUESTION
Before iOS 15, I used UIImagePickerController to capture images and video, and I got mediaType from [UIImagePickerController.InfoKey : Any], then I used kUTTypeImage (in the MobileCoreServices library) to identify the mediaType.
However, When it comes to iOS 15, Xcode complains that kUTTypeImage was deprecated in iOS 15.0. Use UTTypeImage instead. So, I replaced kUTTypeImage with UTTypeImage, but Xcode didn't know it.
Tried searching for some information, but didn't get any clue. I guess I should import the right library, but what is it?
Here is part of the codeοΌ
...ANSWER
Answered 2021-Sep-26 at 06:40It's a bit confusing. First, you'll need to import UniformTypeIdentifiers. Then, replace kUTTypeImage with UTType.image (the Swift version of UTTypeImage).
QUESTION
I am trying to solve a problem without success and am hoping someone could help.
I have looked for similar posts but haven't been able to find anything which solves my problem.
My Scenario is as follows:
I have a UIView on which a number of other UIViews can be placed. These can be moved, scaled and rotated using gesture recognisers (There is no issue here).
The User is able to change the Aspect Ratio of the Main View (the Canvas) and my problem is trying to scale the content of the Canvas to fit into the new destination size.
There are a number of posts with a similar theme e.g:
calculate new size and location on a CGRect
How to create an image of specific size from UIView
But these don't address the changing of ratios multiple times.
My Approach:
When I change the aspect ratio of the canvas, I make use of AVFoundation to calculate an aspect fitted rectangle which the subviews of the canvas should fit:
ANSWER
Answered 2022-Feb-06 at 10:03Here are a few thoughts and findings while playing around with this
1. Is the right scale factor being used?
The scaling you use is a bit custom and cannot be compared directly to the examples which has just 1 scale factor like 2 or 3. However, your scale factor has 2 dimensions but I see you compensate for this to get the minimum of the width and height scaling:
QUESTION
I'm trying to implement a PHPickerViewController using SwiftUI and The Composable Architecture. (Not that I think that's particularly relevant but it might explain why some of my code is like it is).
I've been playing around with this to try and work it out. I created a little sample Project on GitHub which removes The Composable Architecture and keeps the UI super simple.
https://github.com/oliverfoggin/BrokenImagePickers/tree/main
It looks like iOS 15 is breaking on both the UIImagePickerViewController and the PHPickerViewController. (Which makes sense as they both use the same UI under the hood).
I guess the nest step is to determine if the same error occurs when using them in a UIKit app.
My codeMy code is fairly straight forward. It's pretty much just a reimplementation of the same feature that uses UIImagePickerViewController but I wanted to try with the newer APIs.
My code looks like this...
...ANSWER
Answered 2021-Sep-26 at 14:32Well.. this seems to be an iOS bug.
I have cerated a sample project here that shows the bug... https://github.com/oliverfoggin/BrokenImagePickers
And a replica project here written with UIKit that does not... https://github.com/oliverfoggin/UIKit-Image-Pickers
I tried to take a screen recording of this happening but it appears that if any screen recording is happening (whether on device or via QuickTime on the Mac) this suppresses the bug from happening.
I have filed a radar with Apple and sent them both projects to have a look at and LOTS of detail around what's happening. I'll keep this updated with any progress on that.
Hacky workaroundAfter a bit of further investigation I found that you can start with SwiftUI and then present a PHPickerViewController without this crash happening.
From SwiftUI if you present a UIViewControllerRepresentable... and then from there if you present the PHPickerViewController it will not crash.
So I came up with a (very tacky) workaround that avoids this crash.
I first create a UIViewController subclass that I use like a wrapper.
QUESTION
I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).
Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.
I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.
As far I was trying for example changing all places with hasher->check part like here:
ANSWER
Answered 2021-Dec-29 at 02:54Here is a possible solution.
To use a master password, you can use the loginUsingId function
Search the user by username, then check if the password matches the master password, and if so, log in with the user ID that it found

I am working on an application in which I am implementing custom permission. There is subscription-based permission that I can't check in auth guard which will be static and I have implemented helper for permission which checks for route and then check it in user subscription for that route and then redirected to any of the pages on role permission. It is working fine but I need a better approach to implement it with clean code. Here is my implementation

ANSWER
Answered 2021-Dec-31 at 09:25You could try following approach. I did not test it now and have written it off the top of my head but it is based on an approach I used in one project.
Basically you would still use a Guard for this but load the permissions from your service dynamically and based on them either let the user activate the page or redirect to the Unauthorized page. CanActivate subscribes to the Observable for you so you don't have to manage any subscription manually.
QUESTION
I am trying to display rich links in a SwiftUI List and no matter what I try, I can't seem to be able to change the size of the link view (UIViewRepresentable) on screen.
Is there a minimum size for a particular link? And how can I get it. Adding .aspectRatio and clipped() will respect size but the link is heavily clipped. Not sure why the link will not adjust aspectRatio to fit view.
Some of the following code is sourced from the following tutorial: https://www.appcoda.com/linkpresentation-framework/
I am using the following UIViewRepresentable for the LinkView:
...ANSWER
Answered 2021-Dec-29 at 13:24The solution that worked for me was subclassing the linkView overriding the intrinsic content size. Thanks to user1046037's comment, using super.intrinsicContentSize.height will enable it to work dynamically.
QUESTION
Imagine a service ABService with a method isAResponsible: () => boolean and two modules: AModule and BModule.
The question is: Is it possible to switch between AModule and BModule depending on what isAResponsible returns? And how do we 'reroute' and rerender if the value of isAResponsible changes? ABService may have several dependencies to other services so it would be preferable to make use of the DI system somehow.
Example:
If the route of interest is /aorb and ABService.isAResponsible returns true, than we would like to route AModule. If ABService.isAResponsible returns false however we want BModule to manage further routing. Note that everything should happen on a shared route.
I tried it with guards and canActivate/canLoad but didn't succeed:

QUESTION
So, straight to the problem:
I've created a custom UIViewControllerTransitioningDelegate that I use to animate a view from one view controller, to full-screen in another view controller. Im doing this by creating UIViewControllerAnimatedTransitioning-objects that animate the presented view's frame. And it works great! Except when I try to adjust the additionalSafeAreaInsets of the view controller owning the view during dismissal...
It looks like this property is not accounted for when I'm trying to animate the dismissal of the view controller and its view. It works fine during presentation.
The gif below shows how it looks. The red box is the safe area (plus some padding) of the presented view - which I'm trying to compensate for during animation, using the additionalSafeAreaInsets property of the view controller owning the view.
As the gif shows, the safe area is properly adjusted during presentation but not during dismissal.
So, what I want is: use additionalSafeAreaInsets to diminish the effect of the safe area during animation, by setting additionalSafeAreaInsets to the "inverted" values of the safe area. So that the effective safe area starts at 0 and "animates" to the expected value during presentation, and starts at expected value and "animates" to 0 during dismissal. (I'm quoting "animates", since its actually the view's frame that is animated. But UIKit/Auto Layout use these properties when calculating the frames)
Any thoughts on how to battle this issue is great welcome!
The code for the custom UIViewControllerTransitioningDelegate is provided below.
...ANSWER
Answered 2021-Dec-19 at 18:12After some debugging I managed to find a workaround to this problem.
In short, it looks like the safe area is not updated after UIViewController.viewWillDisappear is called, and hence any changes to .additionalSafeAreaInsets is ignored (since these insets modifies the safe area of the view controller's view).
My current workaround is somewhat hacky, but it gets the job done. Since UIViewControllerTransitioningDelegate.animationController(forDismissed...) is called right before UIViewController.viewWillDisappear and UIViewControllerAnimatedTransitioning.animateTransition(using transitionContext...), I start the dismiss animation already in that method. That way the layout calculations for the animation get correct, and the correct safe area is set.
Below is the code for my custom UIViewControllerTransitioningDelegate with the workaround. Note: I've removed the use of .additionalSafeAreaInsets since its not necessary at all! And I've no idea why I thought I needed it in the first place...
QUESTION
We are working on a project which allows us to record some sounds from a microphone with a 5k Hz sample rate with some Low-Pass filter & HighPass filter.
What we are using
We are using AvaudioEngine for this purpose.
We are using AVAudioConverter for downgrading the sample rate.
We are using AVAudioUnitEQ for the LowPass & HighPass filter.
Code
...ANSWER
Answered 2021-Dec-17 at 10:50I think the main problem with this code was that the AVAudioConverter was being created before calling engine.prepare() which can and will change the mainMixerNode output format. Aside from that, there was a redundant connection of mainMixerNode to outputNode, along with a probably incorrect format - mainMixerNode is documented to be automatically created and connected to the output node "on demand". The tap also did not need a format.
QUESTION
It seems that the rules for the compile-time keywords: constexpr, consteval and constinit are defined well enough for compilers to warn if you misapply the label.
It would make sense that (much like inline) the compiler can, in all places, apply rules to determine if, in fact, code could have one of the compile-time keywords applied and, be forced, per language specification, to compile as much as possible as if the compile-time keywords had been applied.
Or, at a minimum, if a compile-time keyword is applied to a function and the code would have qualified with had the correct compile-time keywords been applied. Compile that function, as if all the functions called had the correct compile-time keywords.
Here is a simple example:
...ANSWER
Answered 2021-Nov-08 at 16:30Or, at a minimum, if a compile-time keyword is applied to a function and the code would have qualified with had the correct compile-time keywords been applied.
The basis of your question is the assumption that these keywords are just variations on a theme, that a function which could have some of them ought to have a specific one based on the properties within the function alone.
That's not reasonable.
For functions, any function which could be constexpr could also be consteval. The difference is that one can be called during constant expression evaluation, and the other must be called only during constant expression evaluation. This is not an intrinsic property of the function definition; it is about how the function is to be used.
The compiler should not override the decision of a programmer to be able to use a function at runtime just because the function definition just so happens to also be legit for consteval.
It should also be noted that there is the requirements of a function definition for a consteval function are the same as for a constexpr function.
It is also not possible to know if a function definition ought to be constexpr or not. Remember: while a constexpr function explicitly forbids certain constructs from appearing in the definition, it also permits you to have certain constructs in the definition that aren't allowed to be evaluated during constant evaluation... so long as you never actually allow those code paths to be evaluated during constant evaluation. So there are many function definitions that just so happen to be valid for constexpr even if the programmer didn't intend for them to be evaluated at compile-time.
Lambdas get implicit constexpr definitions only because space in a lambda expression is at a premium.
For variables, implicit constexpr makes even less sense. A variable ought to be constexpr if you intend to use it in a constant expression later on. This requires it to have an initializer that is a constant expression. Implicit constexpr is a problem because you might start relying on the implicit constexpr rule, then change the initializer to no longer be a constant expression and get a strange error in the place where you used its constexpr properties.
It's better to make the user be explicit up-front than to misjudge what the user was trying to do and make a user think something is supposed to be valid when it wasn't intended.
And constinit is solely about ensuring that a user never accidentally uses a non-constant expression to initialize the variable. Making it implicit would make absolutely no sense, as changing the expression to no longer be a constant expression wouldn't cause compilation to fail. Compilers are smart enough to know when a variable is initialized with a constant expression and can decide how to handle that on its own.
