I know it's fun to play around with Core Image filters and you've only seen some of them! This method does exactly what its name says: give it a UIImage and it will write the image to the photo album.
This method takes four parameters: the image to write, who to tell when writing has finished, what method to call, and any context. The context is just like the context value you can use with KVO, as seen in project 4, and again we're not going to use it here.
The first two parameters are quite simple: we know what image we want to save the processed one in the image viewand we also know that we want self the current view controller to be notified when writing has finished.
How to Use Camera and Library to Take Photos in SwiftUI
The third parameter can be provided in two ways: vague and clean, or specific and ugly. It needs to be a selector that lists the method in our view controller that will be called, and it's specified using selector. The method it will call will look like this:.
Previously we've had very simple selectors, like selector shareTapped. Yes, that approach is nice and easy to read, but it's also very vague: it doesn't say what is actually going to happen. The alternative is to be very specific about the method we want called, so you can write this:. This second option is longer, but provides much more information both to Xcode and to other people reading your code, so it's generally preferred.
To be honest, this particular callback is a bit of a wart in iOS, but the fact that it stands out so much is testament to the fact that there are so few warts around!
From here on it's easy, because we just need to write the didFinishSavingWithError method. This must show one of two messages depending on whether we get an error sent to us. The error might be, for example, that the user denied us permission to write to the photo album. This will be sent as an Error?
This parameter is important because if an error has occurred i. And that's it: your app now imports pictures, manipulates them with a Core Image filter and a UISliderthen saves the result back to the photo library.

International Enterprises.Hello, welcome back to our SwiftUI tutorials series. In this article, we are going to learn how to use the photo camera and library picker in SwiftUI to take photos within our iOS apps — a feature that nearly every mobile application needs nowadays, especially with the latest iPhone release, that has 3 cameras!
In Info. If these keys do not give the purpose or the reason is not appropriate, your app will get rejected when you are thinking about submitting it. See the following example. As you can see, we have two methods here: imagePickerController and imagePickerControllerDidCancel corresponding to the two tasks of making a selection and canceling.
We will also declare two parameters:. So we have completed the Image Gallery photo picking section. To take photos with the camera we need to make a small change. In practice, we are going to need a variable to keep track of what kind of source users have chosen to display accordingly.
If you do not declare that line of code, it will show the photo gallery by default. Hope you enjoyed the this SwiftUI tutorial. Happy Coding! Nice tutorial! Simple and effective. That makes this easier to understand. Now that my user has picked the image I would like save it in folder reserved area for images.

Hello everyone, welcome back to our SwiftUI tutorial series. This time, we are going to learn one of the important features of iOS in particular and mobile in general: MapView. While working on the SwiftUI Chat tutorial, we ran into the issue of handling the keyboard animations by adjusting the layout of all the views visible on the screen, depending on whether the keyboard is Read more….
With every release of Xcode, Apple provides us with extremely useful improvements and new features. An image — display the image when the user has made a selection.
We just add some visual effects to make the image more beautiful. Notes: We use the extension with the purpose of showing the code clearly instead of conforming directly. We will also declare two parameters: isShown — keep track of the status of our view is it open or closed? Image — an instance is used to save the selected image.UIImage Swift - Save UIImage

SwiftUI Handling the Keyboard Animations in SwiftUI with ObservedObject While working on the SwiftUI Chat tutorial, we ran into the issue of handling the keyboard animations by adjusting the layout of all the views visible on the screen, depending on whether the keyboard is Read more….Interacting with System directories in your device is often a common task and comes in handy when you need to store some type of data for later use, without the need to fetch from the server or elsewhere.
In this tutorial, you gonna build a quick app that takes pictures using the UIImagePickerController class and saves them inside a folder that you will create in the Document directory of your device. The app will later load those images and populate them in a table view. So head over to the Main. Also, select the ViewController. Now, change the class declaration to the following:. Select the newly added bar button, switch to the Attributes inspector and choose the Camera attribute for System Item property.
Switch to the Assistant editor and make sure the ViewController. Next, ctrl click on the camera bar button and drag a line to the code. Switch back to the Standard editor and select the ViewController. The app will fetch some pictures using the UIImagePickerControllerit will then save those images, precisely ,in a folder inside the Document directory.
The imagesDirectoryPath variable will handle a reference to the images folder inside the Document directory. The images and titles arrays are just where will all images be saved along with their corresponding names. Great, now locate the choosePhoto action method and implement the following code inside:. This will just initialise a UIImagePickerController instance and present it modally to the screen in order to pick an image from the photo library in your device.
The image picker source type is set to photo library by default, good for you as you only want to deal with images here. Remember, this folder will be created inside the Document directory.
The best place and time to create this folder is when the screen first load. The code above will first initialise the images array, then it will create a new path for the new folder under the Document directory. On my simulator, the new path is something like this:.
Before you create the folder, the code above will check whether it does already exist on that path. If not, it will create a new folder with the same path. So far so good, now, once you choose a picture, you want to save it to the ImagePicker directory.
This is the method that will be called on the delegate and provide the selected image to be saved. The code above will simply use the current date and time as the image name, I think this is the best way to prevent redundant images and to avoid conflicting names inside the ImagePicker folder.
