Here is a code snippet that shows a simple List with an onDelete modifier. This modifier expects a closure with one parameter that contains an IndexSet, indicating which rows to delete. To add swipe-to-delete to a Listview, all you need to do is apply the onDelete modifier to a ForEach loop inside a List view. It is pretty straight-forward to use, but also pretty basic (or rather inflexible). This feature was available in SwiftUI right from the beginning. A HStack which stacks views horizontally across the screen, a VStack which stacks views vertically, and a ZStack which layers stacks on top of each other going in to. Using Swipe Actions (this is the most flexible approach, which also gives us a wealth of styling options) The compiler will get confused and see that two views are trying to be returned when only one is expected.Not only does that act as a useful escape hatch for whenever a given use case is not yet natively supported by SwiftUI itself, it also enables us to incrementally migrate an existing UIKit or AppKit. One of SwiftUI’s major strengths is just how well it integrates with both UIKit and AppKit. A VStack is a free-form StackView that contains arbitrary combinations of other views and manages their layout and organization. Deleting and moving items using EditButton and the. SwiftUI and UIKit interoperability - Part 1. It does lazy loading of cells but brings with it a lot of baggage and limitations that stem from the TableView need for delegates, and from the underlying cell-based table view structure.Swipe-to-delete using the onDelete modifier.In this post, we will look at the following features:
UIKit has supported Swipe Actions since iOS 11, but SwiftUI didn’t support Swipe Actions until WWDC 2021.
They provide a well-known and easy-to-use UI affordance to allow users to perform actions on list items. Swipe Actions are used in many apps, most prominently in Apple’s own Mail app. (BTW, another time I had an issue, I had already erased the running IOS image THEN I discovered the system wouldn't load any IOS.In this part of The Ultimate Guide to List Views, we will look at Swipe Actions. Often such was cured by reloading the device even with its existing IOS. Lastly, I have encountered "sick" Cisco devices, those that wouldn't load using tftp. (NB: I once had a new image reload fail because I didn't check.)
Of course, before reloading, insure your newly loaded image is a "good" copy (by doing a image verification check). Sometimes I've found "old" minimal IOS images will fit on flash with the newer image - useful, again, if a new IOS image fails for some reason.īTW, I've very rarely had an issue loading an IOS image after erasing the existing image from flash. (NB: don't forget other Cisco devices, including 3750s, can be tftp servers.) If you get "stuck" with a non-bootable 3750, as Seb mentions, you can then use XMODEM to load a new image.īesides falling back to XMODEM, if you have any other host, that can support tftp, on a shared network that the 3750s is on, you can use it to deal with a botched load. (NB: some of the early 3750s also don't have enough flash to run a 15.x image.) That's not uncommon, the need to remove an existing IOS image, before loading a newer image (at least on earlier devices that often didn't have sufficient flash to contain more than one IOS image.

With the frame modifier, the height of the image is constrained to 100, and content mode is set to fit.

To fix recent vulnerability with smart install ( ) we have been disabling vstack on all our switches as we dont use this feature. The stack is 'lazy,' in that the stack view doesn't create items until it needs to render them onscreen. We have this C3750 switches on our network with IOS version - 12.2(55)SE1.
