method scanFloat was deprecated in iOS 13.0,
func scanFloat(_ result: UnsafeMutablePointer<Float>?) -> Bool
Scans for a float value, returning a found value by reference.
I can use for loop to solve it.
any other advice?
Please read the documentation.
There is an improved replacement
func scanFloat(representation: Scanner.NumberRepresentation = .decimal) -> Float?

i have implemented XCTest case for each module and i'm looking for how to know that launch Image is added in xcasset using xctest case.
Not entirely sure what you're going for here.
You could check if LaunchImage is available by checking the bundle images for the name.
func checkIfLaunchImageAvailable() -> Bool {
for imageName in Bundle.main.paths(forResourcesOfType: "png", inDirectory: nil) {
if imageName.contains("LaunchImage"), UIImage(named: imageName) != nil {
print("Launch image is available!")
return true
}
}
return false
}
And could check using XCTAssertTrue:
XCTAssertTrue(checkIfLaunchImageAvailable)

I'm loading around 500 rows of data into a List. It was okay when I had 10 rows but now that I have 500 it's extremely slow. Is there anything I can do to help it's performance?
List {
SegmentedControl(selection: $feedType) {
ForEach(FeedType.allCases.identified(by: \.self)) { type in
Text(type.rawValue)
}
}
ForEach(store.stories) { story in
NavigationButton(destination: Text("")) {
StoryRow(story: story)
}
}
}

I have a video inside my device but I want to extract the following details of the video(In flutter/dart)-
1.When the video was taken.
2.Duration of the video
3.Type of the Video
4.When the video was taken
Currently i am using Ff-mpeg plugin but it is taking too long time before it returns metadata information.
You may need to use FFMPEG as follows
import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';
class VideoDetail {
final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();
VideoDetail() {
_flutterFFmpeg
.getMediaInformation("<file path or uri>")
.then((info) => print(info));
}
}
Do not forget to add dependency
flutter_ffmpeg: ^0.1.1

Just as the title says, do you know any alternative of AGPushNote for Swift ?
In order to better understand what I was searching for when I found out on SO about this, I would like to .. "detect" when push notifications are incoming and app is active so I can prevent the notifications from showing up and do some of my own stuff instead.
I just published a pod that does exactly that.
Example usage:
import CWNotificationBanner
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
let message = Message(text: "You have an alert")
NotificationBanner.showMessage(message)
let message = Message("You have an alert", displayDuration: 2)
NotificationBanner.showMessage(message)
}
override func viewWillDisappear() {
super.viewWillDisappear()
NotificationBanner.cancelMessage(message, animated: false)
NotificationBanner.cancelAllMessages()
}

In Objective C we used
if([names count]>1){
// array count is greater than one
}
The same way i tried to check in swift. But the complier shouts.
Any idea??
The correct way to write it should be:
if name.count > 1 {
// Your code here
}
Your syntax is incorrect. Brackets are used in Objective-C, not Swift.
Try this:
var shoppingList = ["Eggs", "Milk"]
if(1 < shoppingList.count) {
println( "Greater than one")
}
