swizzle | An esoteric programming language | Interpreter library

Problem:

After successfully building with no errors logged, the app opens to the standard LaunchScreen.storyboard but right after comes a black screen. The Metro Bundler still loads and the app's code goes through to the login screen but the black screen persists and the app is irresponsive to input.

What I Use:

• Hardware: iMac (Retina 5K, 27-inch, Late 2015)
• OS: macOS BigSur 11.2.3
• Simulator: iOS Simulator iPhone 12 (14.4)
• Test Phone: iPhone 7 (14.4)
• XCode Version 12.4 (12D4e)

Relevant Packages:

I’m attempting to swizzle the init methods of UIView and anything that subclasses it. Thus far my attempts only lead to crashes or simply do nothing noticeable.

The outcome in trying to achieve is being able to override the value of the views border colour and width in an attempt to visualise view frames without needing a debugger attached.

Is there any easy way to hook (swizzle) methods in Swift?

i am making app in flutter/firebase and i am experiencing the following error on my visual studio code terminal:-

To my delight, I found that clang will let you write explicit vector code, without resorting to intrinsics, using extended vectors.

For instance, this code:

I'm trying to set up push notifications via Azure NotificationHub (using these guides). Android went fine, but iOS...

No matter what I do, I do not receive any callbacks from RegisterNative / RegisterTemplate methods of SBNotificationHub, and no registrations appear in the hub.

My code (pretty straightforward):

Often for blender scripts have to calculate an encompassing bounding box from a collection of 3D points, for example sake the default blender cube bounding box as input,

I'm using a custom font and somehow the rendering screws up the line height, potentially because of misconfigured descent or leading (?), so that g's and j's are cut off in the last line of the rendered text. I think it might be a problem with this particular font, because Sketch is also exposing similar issues with the font in question, but I feel like I don't understand quite enough about typographic measurements or fonts. I found this Apple documentation page on Typographic Concepts quite insightful.

I looked into the font itself with the test version of FontLab, which I have used for the first time btw - so I've little clue really what I'm looking at. It does seem like the g is going below the configured descent, which seems to be what the last line is. (?) (See: Character view in FontLab, showing the descend of the g)

Via lineSpacing I could adjust the distance between just the lines itself to fix this in the first few lines. I know iOS 14 is going to bring a way to modify the leading of a Text in SwiftUI. But I need to target iOS 13, so that doesn't help.

I've also tried SwiftUI's Text, a normal UILabel.text and UILabel.attributedText with a customized paragraph style, but nothing I adjust there seems to mitigate the problem. The view is not even clipping. Just adding padding to the frame does not help at all. It increases the distance, but the g's and j's are still cut.

What can I do? Subclass UILabel and overwrite the intrinsicContentSize to add some extra space, when there is a g and j in the last line? That feels a) dirty and b) given that padding didn't help, it might not fix the problem?

Is the font itself the problem here? Can I patch the font somehow without making it worse?

Is there any way to modify the leading or the descend height of the font, when I use lower level APIs? Seems like I could go down to CoreText, as CTFontCreateCopyWithAttributes(_:_:_:_:) is a candidate, if I could just modify via attributes the leading, line space or the descend? Can or monkey-patch / swizzle things without shooting myself in the knee? Should I just file a radar a feedback?

Hey i am developing a ios app in flutter and firebase, when i run my app in visual studio code it shows the following in the terminal:-
