Can you help me out in resolving this issue? You should better show all the relevant code if you really think you want to be helped. When the issue is easily reproducible, readers would try to solve the issue.

What sort of project are you using? Xamarin? Unity? Or something else?

but I can't import AVFoundation.framework in my ViewController.swift. You usually write import AVFoundation. No .framework is needed.

Just found out that you have to check both width and height against 0. Looks like either one can be zero too, that's what I just found out Thanks for sharing the info.

Write a Swift program to test whether a value presents sequentially three times in an array of integers or not Without using in-built function. Is this a homework for you? You would get better responses sooner if you could show what you had done till now.

So is there any elegant way to find out if it's being evaluated the second time?  Always be ready for being evaluated multiple times. It crashes the view because of those 0s. You may need to make your method 0-size-tolerant. (Your code looks like an old C-code and very hard to read. I strongly recommend you to follow the modern coding rules. You are writing code in Swift, not C.) var body: some View { NavigationView { GeometryReader { geometryProxy in VStack { ZStack { if geometryProxy.size != .zero { draw_lines_of_quadrant(screen_width: geometryProxy.size.width, screen_height: geometryProxy.size.height) } } } } } }

As far as I tried, GeometryReader gives size 0 at the first time when body is evaluated, but gives the right screen size at the second time. All such things may depend on the inner views. Can you show the definition of draw_lines_of_quadrant(screen_width:screen_height:)? By the way, snake_case_identifiers are not popular in Swift apps. You should better follow the standard coding styles of Swift.

when I click the button nothing happens,  Then your storyboard is broken, and the action of the button is not connected to the IBAction method. Have you connected the action properly on the storyboard? No edit has made after you connected? Are you sure you are instantiating the view controller through the storyboard?

I cannot reproduce the same error with your code, but get Value of type '[ITLibMediaItem]' has no member 'group'. Are you using any sort of extensions providing group(by:)? Please show more context.

As far as I tried your code, crash occurs before keyboard shown: Tap show second view Tap Change state Tap tab 2 Can you clarify how to reproduce your issue?

When I struct my SwiftUI View named Recipe and I assign Hashable, Codable, and Identifiable to it, You usually do not make a View Hashable, Codable nor Identifiable. You make a model type as Hashable, Codable and Identifiable, and construct the view to represent the model. Anyway, please show your code.

10 and x Int and String (or String and String)? You once said: i want to make a function with array  Please clarify: All the parameters, with the types of them and how they affect the result Result type, Array of String? Or Array of Array of String (often used as a 2-D array)? Or something else?

 get this result  Please clarify what are the input to get the result.

Can you show the complete code to reproduce the issue?

i want to make a function with array  So, you want to define a function taking Array and Int. OK? And you have not answered to my other questions. Do you just want to write? No need to create an Array? What will be the values of the Array and Int for the example output: Please clarify all the things needed to write a function.
